This application contains a Sequence Listing in computer readable form, which is incorporated herein by reference.
The present invention relates to cleaning or detergent compositions comprising polypeptides exhibiting beta-glucanase activity and one or more amylases and/or one or more proteases and uses thereof in cleaning or detergent applications and processes such as cleaning hard-surfaces, dish wash and laundering. The present invention further relates to polypeptides having beta-glucanase activity and polynucleotides encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides, e.g. in cleaning or detergent applications and processes such as cleaning hard-surfaces, dish wash and laundering.
Beta-glucans are polysaccharides consisting of glucose units linked by beta-glycosidic bonds. Cellulose is one type of beta-glucan, in which all of the glucose units are linked by beta-1,4-glucosidic bonds. This feature results in the formation of insoluble cellulose micro-fibrils. Enzymatic hydrolysis of cellulose to glucose requires the use of endo beta-glucanases (e.g. EC 3.2.1.4), cellobiohydrolases (e.g. EC 3.2.1.91) and beta-glucosidases (e.g. EC 3.2.1.21).
Beta-glucans can also be linked by beta-1,3-glucosidic bonds (e.g., as found in the cell walls of baker's yeast, Saccharomyces cerevisiae), beta-1,6-glucosidic bonds as well as combinations of beta-1,3-, beta-1,4- and beta-1,6-glucosidic bonds. The combination of beta-1,3- and beta-1,4-glucosidic bonds can be found, e.g. in the soluble fibre from cereals such as oats and barley. In addition, storage polysaccharides found in algae contain 1,3-linked beta-D-glucose residues with various degrees of 1,6-branching. A subgroup of beta-glucanases, also known as laminarinases, can be classified as endo-1,3-beta-glucanases (EC 3.2.1.6 and EC 3.2.1.39) or exo-1,3-beta-glucanases (EC 3.2.1.58). Laminarinases can be used to catalyse the hydrolysis of the beta-1,3-glucosidic bonds, or beta-1,4-glucosidic bonds when the glucose residue whose reducing group is involved in the linkage to be hydrolysed is substituted at C3 to release glucose or oligosaccharides. These enzymes can act on laminarin, lichenin and cereal beta-D-glucans, but not on substrates containing only 1,4-bonds.
Other beta-glucanases (e.g. EC 3.2.1.4) can, for example, perform endohydrolysis of (1,4)-beta-D-glucosidic linkages in cellulose, lichenin and cereal beta-D-glucans and will also hydrolyze 1,4-linkages in beta-D-glucans containing 1,3-linkages. Still other beta-glucanases (e.g., licheninases EC 3.2.1.73)) can hydrolyze (1,4)-beta-D-glucosidic linkages in beta-D-glucans containing (1,3)- and (1,4)-bonds, but not on substrates containing only 1,3- or only 1,4-bonds.
The removal of cereal stains as oat and barley containing stains in dish wash and laundry is a recognised problem, and there is a considerable interest in finding enzymes that can degrade the beta-glucans found therein.
The present invention provides polypeptides of glycoside hydrolyase family 16 (GH16) having beta-glucanase activity (e.g. comprising or consisting of laminarinase (EC 3.2.1.6, EC 3.2.1.39, and/or EC 3.2.1.58) activity) and polynucleotides encoding said polypeptides, which are highly active in degrading different types of beta-glucans (e.g. linear or branched beta-1,3-glucans), and therefore could be used in the aforementioned applications, e.g. in cleaning or detergent applications and processes such as cleaning hard-surfaces, dish wash and laundering. The existing products comprising beta-glucanases have very low effect on this type of beta-glucan as their main enzymatic substrate is cellulose. Therefore, the present invention provides novel beta-glucanases with improved properties (e.g. with significant improvement of performance and/or stability under alkaline conditions; and optionally, beta-glucanases without cellulase activity (e.g. not having endo-cellulase activity on β-1,4 linkages between D-glucose units) (e.g. EC 3.2.1.6, EC 3.2.1.39, and/or EC 3.2.1.58 activity). A difference between use of cellulases and laminarinases on textile in laundry is that the laminarinases do not degrade the fibers of the textile.
Furthermore, some particular solid detergents have pH above 10. The known beta-glucanases are not suitable for these very high pH detergents. The present invention provides novel beta-glucanases with improved properties (e.g. with significant improvement of performance and/or stability under alkaline conditions).

Anti-redeposition: The term “anti-redeposition” or “anti-redeposition effect” means the reduction or prevention of soil from depositing back onto the textile, fabric or hard surface. The anti-redeposition effect can be determined using the Mini-LOM or Mini-TOM wash assay as described in the examples herein (e.g., as in example 14).
Synergistic effect: The term “synergistic effect” means a cooperative action of polypeptides such that a total combined effect of said polypeptides is greater than the sum of the individual enzymatic effects of said polypeptides. Non-limiting examples of synergistic effect include REM synergistic effect of a beta-glucanase polypeptide of the invention and one or more alpha-amylase (and/or one or more proteases).
REM synergistic effect: REM synergistic effect of polypeptides as used herein can be measured based on the analysis of stain removal carried out by using any suitable wash performance methodology (e.g. Wascator bottle wash method). A preferred method for determining the REM synergistic effect is disclosed in Examples disclosed herein, e.g., Example 7.
Beta-glucanase: The term “beta-glucanase” as used herein means an endo-acting enzyme that catalyzes the hydrolysis of a beta-1,3-, beta-1,6- and/or beta-1,4-bonds connecting two glucosyl residues in a beta-glucan. Non-limiting examples of beta-glucanases as defined herein include cellulases (e.g. EC 3.2.1.4, e.g. having endo-cellulase activity on β-1,4 linkages between D-glucose units and laminarinases (e.g. EC 3.2.1.6, EC 3.2.1.39, and/or EC 3.2.1.58), as described below. For purposes of the present invention, beta-glucanase activity is determined according to the procedure described in the Examples. In one aspect of the invention, the polypeptides of the present invention have at least 20%, e.g., at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, or at least 100% of the beta-glucanase activity of the polypeptide having the sequence selected from the group consisting of: SEQ ID NO: 3, SEQ ID NO: 6, SEQ ID NO: 9, SEQ ID NO: 12, SEQ ID NO: 15, SEQ ID NO: 18. Beta-glucanase activity can suitably be measured using beta-glucan as substrate. A preferred assay for determining beta-glucanase activity is disclosed in Example 1 (AZCL-curdlan or pachyman beta-glucan assay). A further subgroup of beta-glucanases as defined herein, also known as a laminarinases (e.g. EC 3.2.1.6, EC 3.2.1.39, and/or EC 3.2.1.58), can also be used to catalyse the hydrolysis of the beta-1,3-glucosidic bonds, or beta-1,4-glucosidic bonds when the glucose residue whose reducing group is involved in the linkage to be hydrolysed is substituted at C3 to release glucose or oligosaccharides. As used herein the term “beta-glucanase activity” comprises laminarinase (e.g. EC 3.2.1.6, EC 3.2.1.39, and/or EC 3.2.1.58) activity.
Beta-glucan: The term “beta-glucan” as used herein means a polysaccharide that only contain glucose as structural components, and in which the glucose units are linked by beta-glycosidic bonds. Non-limiting examples of beta-glucans include beta-D-glucans, beta-1,3-1,4-glucans, mix-linkage beta-glucans, barley beta-glucans, oatmeal beta-glucans, beta-1,3-glucans and beta-1,3-1,6-glucans.
Allelic variant: The term “allelic variant” means any of two or more alternative forms of a gene occupying the same chromosomal locus. Allelic variation arises naturally through mutation, and may result in polymorphism within populations. Gene mutations can be silent (no change in the encoded polypeptide) or may encode polypeptides having altered amino acid sequences. An allelic variant of a polypeptide is a polypeptide encoded by an allelic variant of a gene.
Amylase: The term “amylase” (EC 3.2.1) refers to enzymes which catalyze the hydrolysis of starch, glycogen, and related polysaccharides to oligosaccharides, maltose, or glucose. Amylases are glycoside hydrolases and act on α-1,4-glycosidic bonds. The amylases suitable in the cleaning compositions of the invention are preferably alpha amylases. Alpha-amylases (EC 3.2.1.1) includes 1,4-α-D-glucan glucanohydrolase and glycogenase and are calcium metalloenzymes. By acting at random locations along the starch chain, alpha-amylase breaks down long-chain carbohydrates, ultimately yielding maltotriose and maltose from amylose, or maltose, glucose and “limit dextrin” from amylopectin. Suitable amylases of the present invention are preferably microbial e.g. obtained from bacterial or fungal sources. The term “alpha-amylase activity” means the activity of alpha 1,4-glucan 4 glucanohydrolases, E.C. 3.2.1.1, which constitute a group of enzymes, which catalyze hydrolysis of starch and other linear and branched 1,4 alpha-glucosidic oligo and poly-saccharides. Alpha-amylase activity may be determined by Assay II as described in the Examples herein
Biofilm: The term “biofilm” means any group of microorganisms in which cells stick to each other on a surface, such as a textile, dishware or hard surface. These adherent cells are frequently embedded within a self-produced matrix of extracellular polymeric substance (EPS). Biofilm EPS is a polymeric conglomeration generally composed of extracellular DNA, proteins, and polysaccharides. Biofilms may form on living or non-living surfaces. The microbial cells growing in a biofilm are physiologically distinct from planktonic cells of the same organism, which, by contrast, are single-cells that may float or swim in a liquid medium.
Bacteria living in a biofilm usually have significantly different properties from free-floating bacteria of the same species, as the dense and protected environment of the film allows them to cooperate and interact in various ways. One effect of this environment is increased resistance to detergents and antibiotics, as the dense extracellular matrix and the outer layer of cells protect the interior of the community.
On laundry biofilm producing bacteria can be found among the following species: Acinetobacter sp., Aeromicrobium sp., Brevundimonas sp., Microbacterium sp., Micrococcus luteus, Pseudomonas sp., Staphylococcus epidermidis, and Stenotrophomonas sp.
Carbohydrate binding module: The term “carbohydrate binding module” means the region within a carbohydrate-active enzyme that provides carbohydrate-binding activity (Boraston et al., 2004, Biochem. J. 383: 769-781). A majority of known carbohydrate binding modules (CBMs) are contiguous amino acid sequences with a discrete fold. The carbohydrate binding module (CBM) is typically found either at the N-terminal or at the C-terminal extremity of an enzyme. Some CBMs are known to have specificity for cellulose.
Catalytic domain: The term “catalytic domain” means the region of an enzyme containing the catalytic machinery of the enzyme.
cDNA: The term “cDNA” means a DNA molecule that can be prepared by reverse transcription from a mature, spliced, mRNA molecule obtained from a eukaryotic or prokaryotic cell. cDNA lacks intron sequences that may be present in the corresponding genomic DNA. The initial, primary RNA transcript is a precursor to mRNA that is processed through a series of steps, including splicing, before appearing as mature spliced mRNA.
Cellulolytic enzyme or cellulase: The term “cellulolytic enzyme” or “cellulase” means one or more (e.g., several) enzymes that hydrolyze a cellulosic material. Such enzymes include endoglucanase(s) (e.g. EC 3.2.1.4), cellobiohydrolase(s), beta-glucosidase(s), or combinations thereof. The two basic approaches for measuring cellulolytic enzyme activity include: (1) measuring the total cellulolytic enzyme activity, and (2) measuring the individual cellulolytic enzyme activities (endoglucanases, cellobiohydrolases, and beta-glucosidases) as reviewed in Zhang et al., 2006, Biotechnology Advances 24: 452-481. Total cellulolytic enzyme activity can be measured using insoluble substrates, including Whatman N21 filter paper, microcrystalline cellulose, bacterial cellulose, algal cellulose, cotton, pretreated lignocellulose, etc. The most common total cellulolytic activity assay is the filter paper assay using Whatman N21 filter paper as the substrate. The assay was established by the International Union of Pure and Applied Chemistry (IUPAC) (Ghose, 1987, Pure Appl. Chem. 59: 257-68). Cellulase activity may be determined by Assay III as described in the Examples herein
Cellulosic material: The term “cellulosic material” means any material containing cellulose. The predominant polysaccharide in the primary cell wall of biomass is cellulose, the second most abundant is hemicellulose, and the third is pectin. The secondary cell wall, produced after the cell has stopped growing, also contains polysaccharides and is strengthened by polymeric lignin covalently cross-linked to hemicellulose. Cellulose is a homopolymer of anhydrocellobiose and thus a linear beta-(1-4)-D-glucan, while hemicelluloses include a variety of compounds, such as xylans, xyloglucans, arabinoxylans, and mannans in complex branched structures with a spectrum of substituents. Although generally polymorphous, cellulose is found in plant tissue primarily as an insoluble crystalline matrix of parallel glucan chains. Hemicelluloses usually hydrogen bond to cellulose, as well as to other hemicelluloses, which help stabilize the cell wall matrix.
Cellulose is generally found, for example, in the stems, leaves, hulls, husks, and cobs of plants or leaves, branches, and wood of trees. The cellulosic material can be, but is not limited to, agricultural residue, herbaceous material (including energy crops), municipal solid waste, pulp and paper mill residue, waste paper, and wood (including forestry residue) (see, for example, Wiselogel et al., 1995, in Handbook on Bioethanol (Charles E. Wyman, editor), pp. 105-118, Taylor & Francis, Washington D.C.; Wyman, 1994, Bioresource Technology 50: 3-16; Lynd, 1990, Applied Biochemistry and Biotechnology 24/25: 695-719; Mosier et al., 1999, Recent Progress in Bioconversion of Lignocellulosics, in Advances in Biochemical Engineering/Biotechnology, T. Scheper, managing editor, Volume 65, pp. 23-40, Springer-Verlag, New York). It is understood herein that the cellulose may be in the form of lignocellulose, a plant cell wall material containing lignin, cellulose, and hemicellulose in a mixed matrix. In one aspect, the cellulosic material is any biomass material. In another aspect, the cellulosic material is lignocellulose, which comprises cellulose, hemicelluloses, and lignin.
Coding sequence: The term “coding sequence” means a polynucleotide, which directly specifies the amino acid sequence of a polypeptide. The boundaries of the coding sequence are generally determined by an open reading frame, which begins with a start codon such as ATG, GTG, or TTG and ends with a stop codon such as TAA, TAG, or TGA.

Examples of hemicellulases include, but are not limited to, an acetylmannan esterase, an acetylxylan esterase, an arabinanase, an arabinofuranosidase, a coumaric acid esterase, a feruloyl esterase, a galactosidase, a glucuronidase, a glucuronoyl esterase, a GH5 mannanase, a GH26 mannanase, a mannosidase, a xylanase, and a xylosidase. The substrates for these enzymes, hemicelluloses, are a heterogeneous group of branched and linear polysaccharides that are bound via hydrogen bonds to the cellulose microfibrils in the plant cell wall, crosslinking them into a robust network. Hemicelluloses are also covalently attached to lignin, forming together with cellulose a highly complex structure. The variable structure and organization of hemicelluloses require the concerted action of many enzymes for its complete degradation. The catalytic modules of hemicellulases are either glycoside hydrolases (GHs) that hydrolyze glycosidic bonds, or carbohydrate esterases (CEs), which hydrolyze ester linkages of acetate or ferulic acid side groups. These catalytic modules, based on homology of their primary sequence, can be assigned into GH and CE families. Some families, with an overall similar fold, can be further grouped into clans, marked alphabetically (e.g., GH-A). A most informative and updated classification of these and other carbohydrate active enzymes is available in the Carbohydrate-Active Enzymes (CAZy) database. Hemicellulolytic enzyme activities can be measured according to Ghose and Bisaria, 1987, Pure & Appl. Chem. 59: 1739-1752, at a suitable temperature such as 40° C.-80° C., e.g., 50° C., 55° C., 60° C., 65° C., or 70° C., and a suitable pH such as 4-9, e.g., 5.0, 5.5, 6.0, 6.5, or 7.0.

For example, the nomenclature [F/W] means that the amino acid at this position may be a phenylalanine (Phe, F) or a tryptophan (Trp, W). Amino acids indicated within brackets using this nomenclature may be separated by a vertical line or in some instances no line e.g. [F/W] can also be designated as [FW].
In some instance, a sequence motif includes more than one set of brackets, each of which independently represents a position in a sequence. Thus, G[F/W]GNXEX[Q/E]XY ((SEQ ID NO: 33) means that G, conservative amino acid, is in the first position; either of F or W are in the second position; G, conservative amino acid, is in the third position; N, conservative amino acid is in the fourth position, X, any amino acid, is in the fifth position; E, conservative amino acid is in the sixth position; X, any amino acid, is in the seventh position; either of Q or E are in the eighth position; X, any amino acid, is in the ninth position; and Y, conservative amino acid, is in the tenth position. The motif represented by this designation may then be any of GFGNXEXQXY (SEQ ID NO: 34), GWGNXEXQXY (SEQ ID NO: 36), GFGNXEXEXY (SEQ ID NO: 35), GWGNXEXEXY (SEQ ID NO: 37).
Unless otherwise limited further, the amino acid X (or Xaa) is used herein to represent any of the 20 natural amino acids.
This invention provides the use of polypeptides having beta-glucanase activity and optionally one or more polypeptides having amylase, such as alpha-amylase, activity (and/or one or more polypeptides having protease activity) for cleaning or detergent compositions which have a benefit in removing stains and which can be used in cleaning or detergent applications or for processes such as cleaning hard-surfaces, dish wash and laundering. The invention also provides the use of beta-glucanases that are wash stable in detergent formulations in the presence of amylases. The polypeptide having beta-glucanase activity of the invention may show synergistic effect with one or more polypeptides having amylase, such as alpha-amylase activity (and/or one or more polypeptides having protease activity), e.g., wherein a preferred method for determining the REM synergistic effect is disclosed in the Examples, e.g., Example 7).
Polypeptides useful according to the invention are those having beta-glucanase activity, which are of the laminarinase clade comprising GH16 glycoside hydrolase family polypeptides of bacterial origin from the order Bacillales having laminarinase activity and comprising certain conserved polypeptide motifs.
In one embodiment, the beta-glucanases comprise one or more or all of the conserved polypeptide motifs GEXDXME (SEQ ID NO: 28), GXGNXEXXXY (SEQ ID NO: 29), NXAXGG (SEQ ID NO: 30) and YTS[G/A][K/R] (SEQ ID NO: 31).
For example, one shared motif of the beta-glucanases comprises the GEXDXME (SEQ ID NO: 28) motif. The two glutamic acid (E) residues of the GEXDXME (SEQ ID NO: 28) motif are analogous to residues E132 and E137 of SEQ ID: 27 which are directly involved as catalytic residues and are essential for catalysis. Also relevant is the GEIDIME (SEQ ID NO: 32) motif.
As another example, one shared motif of the beta-glucanases comprises the GXGNXEXXXY (SEQ ID NO: 29) motif. The asparagine (N) and glutamic acid (E) residues in the GXGNXEXXXY (SEQ ID NO: 29) motif are analogous to residue N45 and E47 in SEQ ID: 27 which may form direct or water-mediated hydrogen bonds to the laminarin substrate aiding in positioning the substrate correctly in the catalytic groove of the enzyme. Also relevant is the G[F/W]GNXEX[Q/E]XY (SEQ ID NO: 33) motif, which includes the motifs GFGNXEXQXY (SEQ ID NO: 34), GFGNXEXEXY (SEQ ID NO: 35), GWGNXEXQXY (SEQ ID NO: 36), and GWGNXEXEXY (SEQ ID NO: 37).
Another exemplary motif of the beta-glucanases comprises the NXAXGG (SEQ ID NO: 30) motif. The asparagine residue (N) in the NXAXGG (SEQ ID NO: 30) motif is analogous to the N225 residue in SEQ ID: 27 which is suggested to have a role in substrate binding. Also relevant is the [L/M]NXAXGG (SEQ ID NO: 42) motif, which includes both the LNXAXGG (SEQ ID NO: 43) and MNXAXGG (SEQ ID NO: 44) motifs.
Another motif of the beta-glucanases comprises the YTS[G/A][K/R] (SEQ ID NO: 31) motif. The arginine or lysine in the YTS[G/A][K/R] (SEQ ID NO: 31) motif carries a positive charge and this charge is proposed to be important for correct substrate interaction either through direct or water mediated interaction and is analogous to the R85 residue of the SEQ ID: 27. Thus, the YTS[G/A][K/R] (SEQ ID NO: 31) motif also includes YTSGK (SEQ ID NO: 38), YTSGR (SEQ ID NO: 39), YTSAK (SEQ ID NO: 40), and YTSAR (SEQ ID NO: 41).
Further details are provided in Example 3, herein.

The polypeptide preferably comprises, consists essentially of, or consists of the amino acid sequence of SEQ ID NO: 2, SEQ ID NO: 5, SEQ ID NO: 8, SEQ ID NO: 11, SEQ ID NO: 14, SEQ ID NO: 17 or the mature polypeptide thereof; or is a fragment thereof having beta-glucanase activity. In one aspect, the mature polypeptide is SEQ ID NO: 3, SEQ ID NO: 6, SEQ ID NO: 9, SEQ ID NO: 12, SEQ ID NO: 15, or SEQ ID NO: 18.
In another embodiment, the present invention relates to a polypeptide having beta-glucanase activity encoded by a polynucleotide that hybridizes under very low stringency conditions, low stringency conditions, medium stringency conditions, medium-high stringency conditions, high stringency conditions, or very high stringency conditions with (i) the mature polypeptide coding sequence selected from the group consisting of: SEQ ID NO: 1, SEQ ID NO: 4, SEQ ID NO: 7, SEQ ID NO: 10, SEQ ID NO: 13, SEQ ID NO: 16, (ii) the cDNA sequence thereof, or (iii) the full-length complement of (i) or (ii) (Sambrook et al., 1989, Molecular Cloning, A Laboratory Manual, 2d edition, Cold Spring Harbor, New York). In an embodiment, the polypeptide has been isolated.
The polynucleotide of sequence selected from the group consisting of: SEQ ID NO: 1, SEQ ID NO: 4, SEQ ID NO: 7, SEQ ID NO: 10, SEQ ID NO: 13, SEQ ID NO: 16 or a subsequence thereof, as well as the polypeptide of sequence selected from the group consisting of: SEQ ID NO: 2, SEQ ID NO: 5, SEQ ID NO: 8, SEQ ID NO: 11, SEQ ID NO: 14, SEQ ID NO: 17 or a fragment thereof may be used to design nucleic acid probes to identify and clone DNA encoding polypeptides having beta-glucanase activity from strains of different genera or species according to methods well known in the art. In particular, such probes can be used for hybridization with the genomic DNA or cDNA of a cell of interest, following standard Southern blotting procedures, in order to identify and isolate the corresponding gene therein. Such probes can be considerably shorter than the entire sequence, but should be at least 15, e.g., at least 25, at least 35, or at least 70 nucleotides in length. Preferably, the nucleic acid probe is at least 100 nucleotides in length, e.g., at least 200 nucleotides, at least 300 nucleotides, at least 400 nucleotides, at least 500 nucleotides, at least 600 nucleotides, at least 700 nucleotides, at least 800 nucleotides, or at least 900 nucleotides in length. Both DNA and RNA probes can be used. The probes are typically labeled for detecting the corresponding gene (for example, with 32P, 3H, 35S, biotin, or avidin). Such probes are encompassed by the present invention.
A genomic DNA or cDNA library prepared from such other strains may be screened for DNA that hybridizes with the probes described above and encodes a polypeptide having beta-glucanase activity. Genomic or other DNA from such other strains may be separated by agarose or polyacrylamide gel electrophoresis, or other separation techniques. DNA from the libraries or the separated DNA may be transferred to and immobilized on nitrocellulose or other suitable carrier material. In order to identify a clone or DNA that hybridizes with sequence selected from the group consisting of: SEQ ID NO: 1, SEQ ID NO: 4, SEQ ID NO: 7, SEQ ID NO: 10, SEQ ID NO: 13, SEQ ID NO: 16 or a subsequence thereof, the carrier material is used in a Southern blot.

Molecules to which the nucleic acid probe hybridizes under these conditions can be detected using, for example, X-ray film or any other detection means known in the art.
In one aspect, the nucleic acid probe is nucleotides 109 to 1548 or nucleotides 1 to 1548 of SEQ ID NO: 1. In one aspect, the nucleic acid probe is nucleotides 85 to 870 or nucleotides 1 to 870 of SEQ ID NO: 4. In one aspect, the nucleic acid probe is nucleotides 94 to 1248 or nucleotides 1 to 1248 of SEQ ID NO: 7. In one aspect, the nucleic acid probe is nucleotides 85 to 1230 or nucleotides 1 to 1230 of SEQ ID NO: 10. In one aspect, the nucleic acid probe is nucleotides 73 to 852 or nucleotides 1 to 852 of SEQ ID NO: 13. In one aspect, the nucleic acid probe is nucleotides 70 to 837 or nucleotides 70 to 837 of SEQ ID NO: 16.
In another aspect, the nucleic acid probe is a polynucleotide that encodes the polypeptide of sequence selected from the group consisting of: SEQ ID NO: 2, SEQ ID NO: 5, SEQ ID NO: 8, SEQ ID NO: 11, SEQ ID NO: 14, SEQ ID NO: 17; the mature polypeptide thereof; or a fragment thereof.
In another aspect, the nucleic acid probe is a sequence selected from the group consisting of: SEQ ID NO: 1, SEQ ID NO: 4, SEQ ID NO: 7, SEQ ID NO: 10, SEQ ID NO: 13, or SEQ ID NO: 16.
In another embodiment, the present invention relates to an polypeptide having beta-glucanase activity encoded by a polynucleotide having a sequence identity of at least 60%, e.g., at least 65%, at least 70%, at least 75%, at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, or 100% to the mature polypeptide coding sequence of SEQ ID NO: 1, SEQ ID NO: 4, SEQ ID NO: 7, SEQ ID NO: 10, SEQ ID NO: 13, SEQ ID NO: 16.
In another embodiment, the present invention relates to variants of the mature polypeptide of sequence selected from the group consisting of: SEQ ID NO: 2, SEQ ID NO: 5, SEQ ID NO: 8, SEQ ID NO: 11, SEQ ID NO: 14, SEQ ID NO: 17, or the polypeptide of SEQ ID NO: 3, SEQ ID NO: 6, SEQ ID NO: 9, SEQ ID NO: 12, SEQ ID NO: 15, SEQ ID NO: 18 comprising a substitution, deletion, and/or insertion at one or more (e.g., several) positions. In an embodiment, the number of amino acid substitutions, deletions and/or insertions introduced into the mature polypeptide of sequence selected from the group consisting of: SEQ ID NO: 2, SEQ ID NO: 5, SEQ ID NO: 8, SEQ ID NO: 11, SEQ ID NO: 14, SEQ ID NO: 17, or the polypeptide of SEQ ID NO: 3, SEQ ID NO: 6, SEQ ID NO: 9, SEQ ID NO: 12, SEQ ID NO: 15, SEQ ID NO: 18 is up to 10, e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10. The amino acid changes may be of a minor nature, that is conservative amino acid substitutions or insertions that do not significantly affect the folding and/or activity of the protein; small deletions, typically of 1-30 amino acids; small amino- or carboxyl-terminal extensions, such as an amino-terminal methionine residue; a small linker peptide of up to 20-25 residues; or a small extension that facilitates purification by changing net charge or another function, such as a poly-histidine tract, an antigenic epitope or a binding domain.
Examples of conservative substitutions are within the groups of basic amino acids (arginine, lysine and histidine), acidic amino acids (glutamic acid and aspartic acid), polar amino acids (glutamine and asparagine), hydrophobic amino acids (leucine, isoleucine and valine), aromatic amino acids (phenylalanine, tryptophan and tyrosine), and small amino acids (glycine, alanine, serine, threonine and methionine). Amino acid substitutions that do not generally alter specific activity are known in the art and are described, for example, by H. Neurath and R. L. Hill, 1979, In, The Proteins, Academic Press, New York. Common substitutions are Ala/Ser, Val/Ile, Asp/Glu, Thr/Ser, Ala/Gly, Ala/Thr, Ser/Asn, Ala/Val, Ser/Gly, Tyr/Phe, Ala/Pro, Lys/Arg, Asp/Asn, Leu/Ile, Leu/Val, Ala/Glu, and Asp/Gly.
Alternatively, the amino acid changes are of such a nature that the physico-chemical properties of the polypeptides are altered. For example, amino acid changes may improve the thermal stability of the polypeptide, alter the substrate specificity, change the pH optimum, and the like.
Essential amino acids in a polypeptide can be identified according to procedures known in the art, such as site-directed mutagenesis or alanine-scanning mutagenesis (Cunningham and Wells, 1989, Science 244: 1081-1085). In the latter technique, single alanine mutations are introduced at every residue in the molecule, and the resultant molecules are tested for beta-glucanase activity to identify amino acid residues that are critical to the activity of the molecule. See also, Hilton et al., 1996, J. Biol. Chem. 271: 4699-4708. The active site of the enzyme or other biological interaction can also be determined by physical analysis of structure, as determined by such techniques as nuclear magnetic resonance, crystallography, electron diffraction, or photoaffinity labeling, in conjunction with mutation of putative contact site amino acids. See, for example, de Vos et al., 1992, Science 255: 306-312; Smith et al., 1992, J. Mol. Biol. 224: 899-904; Wlodaver et al., 1992, FEBS Lett. 309: 59-64. The identity of essential amino acids can also be inferred from an alignment with a related polypeptide.
Single or multiple amino acid substitutions, deletions, and/or insertions can be made and tested using known methods of mutagenesis, recombination, and/or shuffling, followed by a relevant screening procedure, such as those disclosed by Reidhaar-Olson and Sauer, 1988, Science 241: 53-57; Bowie and Sauer, 1989, Proc. Natl. Acad. Sci. USA 86: 2152-2156; WO 95/17413; or WO 95/22625. Other methods that can be used include error-prone PCR, phage display (e.g., Lowman et al., 1991, Biochemistry 30: 10832-10837; U.S. Pat. No. 5,223,409; WO 92/06204), and region-directed mutagenesis (Derbyshire et al., 1986, Gene 46: 145; Ner et al., 1988, DNA 7: 127).
Mutagenesis/shuffling methods can be combined with high-throughput, automated screening methods to detect activity of cloned, mutagenized polypeptides expressed by host cells (Ness et al., 1999, Nature Biotechnology 17: 893-896). Mutagenized DNA molecules that encode active polypeptides can be recovered from the host cells and rapidly sequenced using standard methods in the art. These methods allow the rapid determination of the importance of individual amino acid residues in a polypeptide.
The polypeptide may be a hybrid polypeptide in which a region of one polypeptide is fused at the N-terminus or the C-terminus of a region of another polypeptide.
The polypeptide may be a fusion polypeptide or cleavable fusion polypeptide in which another polypeptide is fused at the N-terminus or the C-terminus of the polypeptide of the present invention. A fusion polypeptide is produced by fusing a polynucleotide encoding another polypeptide to a polynucleotide of the present invention. Techniques for producing fusion polypeptides are known in the art, and include ligating the coding sequences encoding the polypeptides so that they are in frame and that expression of the fusion polypeptide is under control of the same promoter(s) and terminator. Fusion polypeptides may also be constructed using intein technology in which fusion polypeptides are created post-translationally (Cooper et al., 1993, EMBO J. 12: 2575-2583; Dawson et al., 1994, Science 266: 776-779).
A fusion polypeptide can further comprise a cleavage site between the two polypeptides. Upon secretion of the fusion protein, the site is cleaved releasing the two polypeptides. Examples of cleavage sites include, but are not limited to, the sites disclosed in Martin et al., 2003, J. Ind. Microbiol. Biotechnol. 3: 568-576; Svetina et al., 2000, J. Biotechnol. 76: 245-251; Rasmussen-Wilson et al., 1997, Appl. Environ. Microbiol. 63: 3488-3493; Ward et al., 1995, Biotechnology 13: 498-503; and Contreras et al., 1991, Biotechnology 9: 378-381; Eaton et al., 1986, Biochemistry 25: 505-512; Collins-Racie et al., 1995, Biotechnology 13: 982-987; Carter et al., 1989, Proteins: Structure, Function, and Genetics 6: 240-248; and Stevens, 2003, Drug Discovery World 4: 35-48.

It will be understood that for the aforementioned species, the invention encompasses both the perfect and imperfect states, and other taxonomic equivalents, e.g., anamorphs, regardless of the species name by which they are known.

Once a polynucleotide encoding a polypeptide has been detected with the probe(s), the polynucleotide can be isolated or cloned by utilizing techniques that are known to those of ordinary skill in the art (see, e.g., Sambrook et al., 1989, supra).

The polynucleotide encoding the catalytic domain may be obtained from any prokaryotic, eukaryotic, or other source.
The polypeptides may further comprise a linker between the catalytic domain and the carbohydrate binding module.
The present invention also relates to polynucleotides encoding a polypeptide, a catalytic domain, or carbohydrate binding module of the present invention, as described herein. In an embodiment, the polynucleotide encoding the polypeptide, catalytic domain, or carbohydrate binding module of the present invention has been isolated.
The techniques used to isolate or clone a polynucleotide are known in the art and include isolation from genomic DNA or cDNA, or a combination thereof. The cloning of the polynucleotides from genomic DNA can be effected, e.g., by using the well known polymerase chain reaction (PCR) or antibody screening of expression libraries to detect cloned DNA fragments with shared structural features. See, e.g., Innis et al., 1990, PCR: A Guide to Methods and Application, Academic Press, New York. Other nucleic acid amplification procedures such as ligase chain reaction (LCR), ligation activated transcription (LAT) and polynucleotide-based amplification (NASBA) may be used. The polynucleotides may be cloned from a strain of Bacillus, or a related organism and thus, for example, may be an allelic or species variant of the polypeptide encoding region of the polynucleotide.
Modification of a polynucleotide encoding a polypeptide of the present invention may be necessary for synthesizing polypeptides substantially similar to the polypeptide. The term “substantially similar” to the polypeptide refers to non-naturally occurring forms of the polypeptide. These polypeptides may differ in some engineered way from the polypeptide isolated from its native source, e.g., variants that differ in specific activity, thermostability, pH optimum, or the like. The variants may be constructed on the basis of the polynucleotide presented as the mature polypeptide coding sequence of sequence selected from the group consisting of: SEQ ID NO: 1, SEQ ID NO: 4, SEQ ID NO: 7, SEQ ID NO: 10, SEQ ID NO: 13, SEQ ID NO: 16, e.g., a subsequence thereof, and/or by introduction of nucleotide substitutions that do not result in a change in the amino acid sequence of the polypeptide, but which correspond to the codon usage of the host organism intended for production of the enzyme, or by introduction of nucleotide substitutions that may give rise to a different amino acid sequence. For a general description of nucleotide substitution, see, e.g., Ford et al., 1991, Protein Expression and Purification 2: 95-107.
The present invention also relates to nucleic acid constructs comprising a polynucleotide of the present invention operably linked to one or more control sequences that direct the expression of the coding sequence in a suitable host cell under conditions compatible with the control sequences.
The polynucleotide may be manipulated in a variety of ways to provide for expression of the polypeptide. Manipulation of the polynucleotide prior to its insertion into a vector may be desirable or necessary depending on the expression vector. The techniques for modifying polynucleotides utilizing recombinant DNA methods are well known in the art.
The control sequence may be a promoter, a polynucleotide that is recognized by a host cell for expression of a polynucleotide encoding a polypeptide of the present invention. The promoter contains transcriptional control sequences that mediate the expression of the polypeptide. The promoter may be any polynucleotide that shows transcriptional activity in the host cell including variant, truncated, and hybrid promoters, and may be obtained from genes encoding extracellular or intracellular polypeptides either homologous or heterologous to the host cell.

Other useful promoters for yeast host cells are described by Romanos et al., 1992, Yeast 8: 423-488.
The control sequence may also be a transcription terminator, which is recognized by a host cell to terminate transcription. The terminator is operably linked to the 3′-terminus of the polynucleotide encoding the polypeptide. Any terminator that is functional in the host cell may be used in the present invention.
Preferred terminators for bacterial host cells are obtained from the genes for Bacillus clausii alkaline protease (aprH), Bacillus licheniformis alpha-amylase (amyL), and Escherichia coli ribosomal RNA (rrnB).
Preferred terminators for filamentous fungal host cells are obtained from the genes for Aspergillus nidulans acetamidase, Aspergillus nidulans anthranilate synthase, Aspergillus niger glucoamylase, Aspergillus niger alpha-glucosidase, Aspergillus oryzae TAKA amylase, Fusarium oxysporum trypsin-like protease, Trichoderma reesei beta-glucosidase, Trichoderma reesei cellobiohydrolase I, Trichoderma reesei cellobiohydrolase II, Trichoderma reesei endoglucanase I, Trichoderma reesei endoglucanase II, Trichoderma reesei endoglucanase III, Trichoderma reesei endoglucanase V, Trichoderma reesei xylanase I, Trichoderma reesei xylanase II, Trichoderma reesei xylanase III, Trichoderma reesei beta-xylosidase, and Trichoderma reesei translation elongation factor.
Preferred terminators for yeast host cells are obtained from the genes for Saccharomyces cerevisiae enolase, Saccharomyces cerevisiae cytochrome C (CYC1), and Saccharomyces cerevisiae glyceraldehyde-3-phosphate dehydrogenase. Other useful terminators for yeast host cells are described by Romanos et al., 1992, supra.
The control sequence may also be an mRNA stabilizer region downstream of a promoter and upstream of the coding sequence of a gene which increases expression of the gene.
Examples of suitable mRNA stabilizer regions are obtained from a Bacillus thuringiensis cryIIIA gene (WO 94/25612) and a Bacillus subtilis SP82 gene (Hue et al., 1995, Journal of Bacteriology 177: 3465-3471).
The control sequence may also be a leader, a nontranslated region of an mRNA that is important for translation by the host cell. The leader is operably linked to the 5′-terminus of the polynucleotide encoding the polypeptide. Any leader that is functional in the host cell may be used.
Preferred leaders for filamentous fungal host cells are obtained from the genes for Aspergillus oryzae TAKA amylase and Aspergillus nidulans triose phosphate isomerase.
Suitable leaders for yeast host cells are obtained from the genes for Saccharomyces cerevisiae enolase (ENO-1), Saccharomyces cerevisiae 3-phosphoglycerate kinase, Saccharomyces cerevisiae alpha-factor, and Saccharomyces cerevisiae alcohol dehydrogenase/glyceraldehyde-3-phosphate dehydrogenase (ADH2/GAP).
The control sequence may also be a polyadenylation sequence, a sequence operably linked to the 3′-terminus of the polynucleotide and, when transcribed, is recognized by the host cell as a signal to add polyadenosine residues to transcribed mRNA. Any polyadenylation sequence that is functional in the host cell may be used.
Preferred polyadenylation sequences for filamentous fungal host cells are obtained from the genes for Aspergillus nidulans anthranilate synthase, Aspergillus niger glucoamylase, Aspergillus niger alpha-glucosidase Aspergillus oryzae TAKA amylase, and Fusarium oxysporum trypsin-like protease.
Useful polyadenylation sequences for yeast host cells are described by Guo and Sherman, 1995, Mol. Cellular Biol. 15: 5983-5990.
The control sequence may also be a signal peptide coding region that encodes a signal peptide linked to the N-terminus of a polypeptide and directs the polypeptide into the cell's secretory pathway. The 5′-end of the coding sequence of the polynucleotide may inherently contain a signal peptide coding sequence naturally linked in translation reading frame with the segment of the coding sequence that encodes the polypeptide. Alternatively, the 5′-end of the coding sequence may contain a signal peptide coding sequence that is foreign to the coding sequence. A foreign signal peptide coding sequence may be required where the coding sequence does not naturally contain a signal peptide coding sequence. Alternatively, a foreign signal peptide coding sequence may simply replace the natural signal peptide coding sequence in order to enhance secretion of the polypeptide. However, any signal peptide coding sequence that directs the expressed polypeptide into the secretory pathway of a host cell may be used.
Effective signal peptide coding sequences for bacterial host cells are the signal peptide coding sequences obtained from the genes for Bacillus NCIB 11837 maltogenic amylase, Bacillus licheniformis subtilisin, Bacillus licheniformis beta-lactamase, Bacillus stearothermophilus alpha-amylase, Bacillus stearothermophilus neutral proteases (nprT, nprS, nprM), and Bacillus subtilis prsA. Further signal peptides are described by Simonen and Palva, 1993, Microbiological Reviews 57: 109-137.
Effective signal peptide coding sequences for filamentous fungal host cells are the signal peptide coding sequences obtained from the genes for Aspergillus niger neutral amylase, Aspergillus niger glucoamylase, Aspergillus oryzae TAKA amylase, Humicola insolens cellulase, Humicola insolens endoglucanase V, Humicola lanuginosa lipase, and Rhizomucor miehei aspartic proteinase.
Useful signal peptides for yeast host cells are obtained from the genes for Saccharomyces cerevisiae alpha-factor and Saccharomyces cerevisiae invertase. Other useful signal peptide coding sequences are described by Romanos et al., 1992, supra.
The control sequence may also be a propeptide coding sequence that encodes a propeptide positioned at the N-terminus of a polypeptide. The resultant polypeptide is known as a proenzyme or propolypeptide (or a zymogen in some cases). A propolypeptide is generally inactive and can be converted to an active polypeptide by catalytic or autocatalytic cleavage of the propeptide from the propolypeptide. The propeptide coding sequence may be obtained from the genes for Bacillus subtilis alkaline protease (aprE), Bacillus subtilis neutral protease (nprT), Myceliophthora thermophila laccase (WO 95/33836), Rhizomucor miehei aspartic proteinase, and Saccharomyces cerevisiae alpha-factor.
Where both signal peptide and propeptide sequences are present, the propeptide sequence is positioned next to the N-terminus of a polypeptide and the signal peptide sequence is positioned next to the N-terminus of the propeptide sequence.
It may also be desirable to add regulatory sequences that regulate expression of the polypeptide relative to the growth of the host cell. Examples of regulatory sequences are those that cause expression of the gene to be turned on or off in response to a chemical or physical stimulus, including the presence of a regulatory compound. Regulatory sequences in prokaryotic systems include the lac, tac, and trp operator systems. In yeast, the ADH2 system or GAL1 system may be used. In filamentous fungi, the Aspergillus niger glucoamylase promoter, Aspergillus oryzae TAKA alpha-amylase promoter, and Aspergillus oryzae glucoamylase promoter, Trichoderma reesei cellobiohydrolase I promoter, and Trichoderma reesei cellobiohydrolase II promoter may be used. Other examples of regulatory sequences are those that allow for gene amplification. In eukaryotic systems, these regulatory sequences include the dihydrofolate reductase gene that is amplified in the presence of methotrexate, and the metallothionein genes that are amplified with heavy metals. In these cases, the polynucleotide encoding the polypeptide would be operably linked to the regulatory sequence.
The present invention also relates to recombinant expression vectors comprising a polynucleotide of the present invention, a promoter, and transcriptional and translational stop signals. The various nucleotide and control sequences may be joined together to produce a recombinant expression vector that may include one or more convenient restriction sites to allow for insertion or substitution of the polynucleotide encoding the polypeptide at such sites. Alternatively, the polynucleotide may be expressed by inserting the polynucleotide or a nucleic acid construct comprising the polynucleotide into an appropriate vector for expression. In creating the expression vector, the coding sequence is located in the vector so that the coding sequence is operably linked with the appropriate control sequences for expression.
The recombinant expression vector may be any vector (e.g., a plasmid or virus) that can be conveniently subjected to recombinant DNA procedures and can bring about expression of the polynucleotide. The choice of the vector will typically depend on the compatibility of the vector with the host cell into which the vector is to be introduced. The vector may be a linear or closed circular plasmid.
The vector may be an autonomously replicating vector, i.e., a vector that exists as an extrachromosomal entity, the replication of which is independent of chromosomal replication, e.g., a plasmid, an extrachromosomal element, a minichromosome, or an artificial chromosome. The vector may contain any means for assuring self-replication. Alternatively, the vector may be one that, when introduced into the host cell, is integrated into the genome and replicated together with the chromosome(s) into which it has been integrated. Furthermore, a single vector or plasmid or two or more vectors or plasmids that together contain the total DNA to be introduced into the genome of the host cell, or a transposon, may be used.
The vector preferably contains one or more selectable markers that permit easy selection of transformed, transfected, transduced, or the like cells. A selectable marker is a gene the product of which provides for biocide or viral resistance, resistance to heavy metals, prototrophy to auxotrophs, and the like.
Examples of bacterial selectable markers are Bacillus licheniformis or Bacillus subtilis dal genes, or markers that confer antibiotic resistance such as ampicillin, chloramphenicol, kanamycin, neomycin, spectinomycin, or tetracycline resistance. Suitable markers for yeast host cells include, but are not limited to, ADE2, HIS3, LEU2, LYS2, MET3, TRP1, and URA3. Selectable markers for use in a filamentous fungal host cell include, but are not limited to, adeA (phosphoribosylaminoimidazole-succinocarboxamide synthase), adeB (phosphoribosyl-aminoimidazole synthase), amdS (acetamidase), argB (ornithine carbamoyltransferase), bar (phosphinothricin acetyltransferase), hph (hygromycin phosphotransferase), niaD (nitrate reductase), pyrG (orotidine-5′-phosphate decarboxylase), sC (sulfate adenyltransferase), and trpC (anthranilate synthase), as well as equivalents thereof. Preferred for use in an Aspergillus cell are Aspergillus nidulans or Aspergillus oryzae amdS and pyrG genes and a Streptomyces hygroscopicus bar gene. Preferred for use in a Trichoderma cell are adeA, adeB, amdS, hph, and pyrG genes.
The selectable marker may be a dual selectable marker system as described in WO 2010/039889. In one aspect, the dual selectable marker is an hph-tk dual selectable marker system.
The vector preferably contains an element(s) that permits integration of the vector into the host cell's genome or autonomous replication of the vector in the cell independent of the genome.
For integration into the host cell genome, the vector may rely on the polynucleotide's sequence encoding the polypeptide or any other element of the vector for integration into the genome by homologous or non-homologous recombination. Alternatively, the vector may contain additional polynucleotides for directing integration by homologous recombination into the genome of the host cell at a precise location(s) in the chromosome(s). To increase the likelihood of integration at a precise location, the integrational elements should contain a sufficient number of nucleic acids, such as 100 to 10,000 base pairs, 400 to 10,000 base pairs, and 800 to 10,000 base pairs, which have a high degree of sequence identity to the corresponding target sequence to enhance the probability of homologous recombination. The integrational elements may be any sequence that is homologous with the target sequence in the genome of the host cell. Furthermore, the integrational elements may be non-encoding or encoding polynucleotides. On the other hand, the vector may be integrated into the genome of the host cell by non-homologous recombination.
For autonomous replication, the vector may further comprise an origin of replication enabling the vector to replicate autonomously in the host cell in question. The origin of replication may be any plasmid replicator mediating autonomous replication that functions in a cell. The term “origin of replication” or “plasmid replicator” means a polynucleotide that enables a plasmid or vector to replicate in vivo.
Examples of bacterial origins of replication are the origins of replication of plasmids pBR322, pUC19, pACYC177, and pACYC184 permitting replication in E. coli, and pUB110, pE194, pTA1060, and pAMß1 permitting replication in Bacillus.
Examples of origins of replication for use in a yeast host cell are the 2 micron origin of replication, ARS1, ARS4, the combination of ARS1 and CEN3, and the combination of ARS4 and CEN6.
Examples of origins of replication useful in a filamentous fungal cell are AMA1 and ANSI (Gems et al., 1991, Gene 98: 61-67; Cullen et al., 1987, Nucleic Acids Res. 15: 9163-9175; WO 00/24883). Isolation of the AMA1 gene and construction of plasmids or vectors comprising the gene can be accomplished according to the methods disclosed in WO 00/24883.
More than one copy of a polynucleotide of the present invention may be inserted into a host cell to increase production of a polypeptide. An increase in the copy number of the polynucleotide can be obtained by integrating at least one additional copy of the sequence into the host cell genome or by including an amplifiable selectable marker gene with the polynucleotide where cells containing amplified copies of the selectable marker gene, and thereby additional copies of the polynucleotide, can be selected for by cultivating the cells in the presence of the appropriate selectable agent.
The procedures used to ligate the elements described above to construct the recombinant expression vectors of the present invention are well known to one skilled in the art (see, e.g., Sambrook et al., 1989, supra).
The present invention also relates to recombinant host cells, comprising a polynucleotide of the present invention operably linked to one or more control sequences that direct the production of a polypeptide of the present invention. A construct or vector comprising a polynucleotide is introduced into a host cell so that the construct or vector is maintained as a chromosomal integrant or as a self-replicating extra-chromosomal vector as described earlier. The term “host cell” encompasses any progeny of a parent cell that is not identical to the parent cell due to mutations that occur during replication. The choice of a host cell will to a large extent depend upon the gene encoding the polypeptide and its source.
The host cell may be any cell useful in the recombinant production of a polypeptide of the present invention, e.g., a prokaryote or a eukaryote.
The prokaryotic host cell may be any Gram-positive or Gram-negative bacterium. Gram-positive bacteria include, but are not limited to, Bacillus, Clostridium, Enterococcus, Geobacillus, Lactobacillus, Lactococcus, Oceanobacillus, Staphylococcus, Streptococcus, and Streptomyces. Gram-negative bacteria include, but are not limited to, Campylobacter, E. coli, Flavobacterium, Fusobacterium, Helicobacter, Ilyobacter, Neisseria, Pseudomonas, Salmonella, and Ureaplasma.
The bacterial host cell may be any Bacillus cell including, but not limited to, Bacillus alkalophilus, Bacillus amyloliquefaciens, Bacillus brevis, Bacillus circulans, Bacillus clausii, Bacillus coagulans, Bacillus firmus, Bacillus lautus, Bacillus lentus, Bacillus licheniformis, Bacillus megaterium, Bacillus pumilus, Bacillus stearothermophilus, Bacillus subtilis, Bacillus sp-62449, Bacillus akibai, Bacillus agaradhaerens, Bacillus mojavensis and Bacillus thuringiensis cells.
The bacterial host cell may also be any Streptococcus cell including, but not limited to, Streptococcus equisimilis, Streptococcus pyogenes, Streptococcus uberis, and Streptococcus equi subsp. Zooepidemicus cells.
The bacterial host cell may also be any Streptomyces cell including, but not limited to, Streptomyces achromogenes, Streptomyces avermitilis, Streptomyces coelicolor, Streptomyces griseus, and Streptomyces lividans cells.
The introduction of DNA into a Bacillus cell may be effected by protoplast transformation (see, e.g., Chang and Cohen, 1979, Mol. Gen. Genet. 168: 111-115), competent cell transformation (see, e.g., Young and Spizizen, 1961, J. Bacteriol. 81: 823-829, or Dubnau and Davidoff-Abelson, 1971, J. Mol. Biol. 56: 209-221), electroporation (see, e.g., Shigekawa and Dower, 1988, Biotechniques 6: 742-751), or conjugation (see, e.g., Koehler and Thorne, 1987, J. Bacteriol. 169: 5271-5278). The introduction of DNA into an E. coli cell may be effected by protoplast transformation (see, e.g., Hanahan, 1983, J. Mol. Biol. 166: 557-580) or electroporation (see, e.g., Dower et al., 1988, Nucleic Acids Res. 16: 6127-6145). The introduction of DNA into a Streptomyces cell may be effected by protoplast transformation, electroporation (see, e.g., Gong et al., 2004, Folia Microbiol. (Praha) 49: 399-405), conjugation (see, e.g., Mazodier et al., 1989, J. Bacteriol. 171: 3583-3585), or transduction (see, e.g., Burke et al., 2001, Proc. Natl. Acad. Sci. USA 98: 6289-6294). The introduction of DNA into a Pseudomonas cell may be effected by electroporation (see, e.g., Choi et al., 2006, J. Microbiol. Methods 64: 391-397) or conjugation (see, e.g., Pinedo and Smets, 2005, Appl. Environ. Microbiol. 71: 51-57). The introduction of DNA into a Streptococcus cell may be effected by natural competence (see, e.g., Perry and Kuramitsu, 1981, Infect. Immun. 32: 1295-1297), protoplast transformation (see, e.g., Catt and Jollick, 1991, Microbios 68: 189-207), electroporation (see, e.g., Buckley et al., 1999, Appl. Environ. Microbiol. 65: 3800-3804), or conjugation (see, e.g., Clewell, 1981, Microbiol. Rev. 45: 409-436). However, any method known in the art for introducing DNA into a host cell can be used.
The host cell may also be a eukaryote, such as a mammalian, insect, plant, or fungal cell.
The host cell may be a fungal cell. “Fungi” as used herein includes the phyla Ascomycota, Basidiomycota, Chytridiomycota, and Zygomycota as well as the Oomycota and all mitosporic fungi (as defined by Hawksworth et al., In, Ainsworth and Bisby's Dictionary of The Fungi, 8th edition, 1995, CAB International, University Press, Cambridge, UK).
The fungal host cell may be a yeast cell. “Yeast” as used herein includes ascosporogenous yeast (Endomycetales), basidiosporogenous yeast, and yeast belonging to the Fungi Imperfecti (Blastomycetes). Since the classification of yeast may change in the future, for the purposes of this invention, yeast shall be defined as described in Biology and Activities of Yeast (Skinner, Passmore, and Davenport, editors, Soc. App. Bacteriol. Symposium Series No. 9, 1980).
The yeast host cell may be a Candida, Hansenula, Kluyveromyces, Pichia, Saccharomyces, Schizosaccharomyces, or Yarrowia cell, such as a Kluyveromyces lactis, Saccharomyces carlsbergensis, Saccharomyces cerevisiae, Saccharomyces diastaticus, Saccharomyces douglasii, Saccharomyces kluyveri, Saccharomyces norbensis, Saccharomyces oviformis, or Yarrowia lipolytica cell.
The fungal host cell may be a filamentous fungal cell. “Filamentous fungi” include all filamentous forms of the subdivision Eumycota and Oomycota (as defined by Hawksworth et al., 1995, supra). The filamentous fungi are generally characterized by a mycelial wall composed of chitin, cellulose, glucan, chitosan, mannan, and other complex polysaccharides. Vegetative growth is by hyphal elongation and carbon catabolism is obligately aerobic. In contrast, vegetative growth by yeasts such as Saccharomyces cerevisiae is by budding of a unicellular thallus and carbon catabolism may be fermentative.
The filamentous fungal host cell may be an Acremonium, Aspergillus, Aureobasidium, Bjerkandera, Ceriporiopsis, Chrysosporium, Coprinus, Coriolus, Cryptococcus, Filibasidium, Fusarium, Humicola, Magnaporthe, Mucor, Myceliophthora, Neocallimastix, Neurospora, Paecilomyces, Penicillium, Phanerochaete, Phlebia, Piromyces, Pleurotus, Schizophyllum, Talaromyces, Thermoascus, Thielavia, Tolypocladium, Trametes, or Trichoderma cell. For example, the filamentous fungal host cell may be an Aspergillus awamori, Aspergillus foetidus, Aspergillus fumigatus, Aspergillus japonicus, Aspergillus nidulans, Aspergillus niger, Aspergillus oryzae, Bjerkandera adusta, Ceriporiopsis aneirina, Ceriporiopsis caregiea, Ceriporiopsis gilvescens, Ceriporiopsis pannocinta, Ceriporiopsis rivulosa, Ceriporiopsis subrufa, Ceriporiopsis subvermispora, Chrysosporium inops, Chrysosporium keratinophilum, Chrysosporium lucknowense, Chrysosporium merdarium, Chrysosporium pannicola, Chrysosporium queenslandicum, Chrysosporium tropicum, Chrysosporium zonatum, Coprinus cinereus, Coriolus hirsutus, Fusarium bactridioides, Fusarium cerealis, Fusarium crookwellense, Fusarium culmorum, Fusarium graminearum, Fusarium graminum, Fusarium heterosporum, Fusarium negundi, Fusarium oxysporum, Fusarium reticulatum, Fusarium roseum, Fusarium sambucinum, Fusarium sarcochroum, Fusarium sporotrichioides, Fusarium sulphureum, Fusarium torulosum, Fusarium trichothecioides, Fusarium venenatum, Humicola insolens, Humicola lanuginosa, Mucor miehei, Myceliophthora thermophila, Neurospora crassa, Penicillium purpurogenum, Phanerochaete chrysosporium, Phlebia radiata, Pleurotus etyngii, Thielavia terrestris, Trametes villosa, Trametes versicolor, Trichoderma harzianum, Trichoderma Trichoderma longibrachiatum, Trichoderma reesei, or Trichoderma viride cell.
Fungal cells may be transformed by a process involving protoplast formation, transformation of the protoplasts, and regeneration of the cell wall in a manner known per se. Suitable procedures for transformation of Aspergillus and Trichoderma host cells are described in EP 238023, Yelton et al., 1984, Proc. Natl. Acad. Sci. USA 81: 1470-1474, and Christensen et al., 1988, Bio/Technology 6: 1419-1422. Suitable methods for transforming Fusarium species are described by Malardier et al., 1989, Gene 78: 147-156, and WO 96/00787. Yeast may be transformed using the procedures described by Becker and Guarente, In Abelson, J. N. and Simon, M. I., editors, Guide to Yeast Genetics and Molecular Biology, Methods in Enzymology, Volume 194, pp 182-187, Academic Press, Inc., New York; Ito et al., 1983, J. Bacteriol. 153: 163; and Hinnen et al., 1978, Proc. Natl. Acad. Sci. USA 75: 1920.
The present invention also relates to methods of producing a polypeptide of the present invention (e.g., in vitro or ex vivo methods of production), comprising (a) cultivating a cell, which in its wild-type form produces the polypeptide, under conditions conducive for production of the polypeptide; and optionally, (b) recovering the polypeptide. In one aspect, the cell is a Bacillus cell. In another aspect, the cell is a Thermobacillus species, a Paenibacillus species, a Cohnella species, or a Bacillus species cell.
The present invention also relates to methods of producing a polypeptide of the present invention (e.g., in vitro or ex vivo methods of production), comprising (a) cultivating a recombinant host cell of the present invention under conditions conducive for production of the polypeptide; and optionally, (b) recovering the polypeptide.
The host cells are cultivated in a nutrient medium suitable for production of the polypeptide using methods known in the art. For example, the cells may be cultivated by shake flask cultivation, or small-scale or large-scale fermentation (including continuous, batch, fed-batch, or solid state fermentations) in laboratory or industrial fermentors in a suitable medium and under conditions allowing the polypeptide to be expressed and/or isolated. The cultivation takes place in a suitable nutrient medium comprising carbon and nitrogen sources and inorganic salts, using procedures known in the art. Suitable media are available from commercial suppliers or may be prepared according to published compositions (e.g., in catalogues of the American Type Culture Collection). If the polypeptide is secreted into the nutrient medium, the polypeptide can be recovered directly from the medium. If the polypeptide is not secreted, it can be recovered from cell lysates.
The polypeptide may be detected using methods known in the art that are specific for the polypeptides. These detection methods include, but are not limited to, use of specific antibodies, formation of an enzyme product, or disappearance of an enzyme substrate. For example, an enzyme assay may be used to determine the activity of the polypeptide.
The polypeptide may be recovered using methods known in the art. For example, the polypeptide may be recovered from the nutrient medium by conventional procedures including, but not limited to, collection, centrifugation, filtration, extraction, spray-drying, evaporation, or precipitation. In one aspect, a fermentation broth comprising the polypeptide is recovered.
The polypeptide may be purified by a variety of procedures known in the art including, but not limited to, chromatography (e.g., ion exchange, affinity, hydrophobic, chromatofocusing, and size exclusion), electrophoretic procedures (e.g., preparative isoelectric focusing), differential solubility (e.g., ammonium sulfate precipitation), SDS-PAGE, or extraction (see, e.g., Protein Purification, Janson and Ryden, editors, VCH Publishers, New York, 1989) to obtain substantially pure polypeptides.
In an alternative aspect, the polypeptide is not recovered, but rather a host cell of the present invention expressing the polypeptide is used as a source of the polypeptide.
The present invention also relates to isolated plants, e.g., a transgenic plant, plant part, or plant cell, comprising a polynucleotide of the present invention so as to express and produce a polypeptide or domain in recoverable quantities. The polypeptide or domain may be recovered from the plant or plant part. Alternatively, the plant or plant part containing the polypeptide or domain may be used as such for improving the quality of a food or feed, e.g., improving nutritional value, palatability, and rheological properties, or to destroy an antinutritive factor.
The transgenic plant can be dicotyledonous (a dicot) or monocotyledonous (a monocot). Examples of monocot plants are grasses, such as meadow grass (blue grass, Poa), forage grass such as Festuca, Lolium, temperate grass, such as Agrostis, and cereals, e.g., wheat, oats, rye, barley, rice, sorghum, and maize (corn).
Examples of dicot plants are tobacco, legumes, such as lupins, potato, sugar beet, pea, bean and soybean, and cruciferous plants (family Brassicaceae), such as cauliflower, rape seed, and the closely related model organism Arabidopsis thaliana.
Examples of plant parts are stem, callus, leaves, root, fruits, seeds, and tubers as well as the individual tissues comprising these parts, e.g., epidermis, mesophyll, parenchyme, vascular tissues, meristems.
Plant cells and specific plant cell compartments, such as chloroplasts, apoplasts, mitochondria, vacuoles, peroxisomes and cytoplasm are also considered to be a plant part.
Also included within the scope of the present invention are the progeny of such plants, plant parts, and plant cells.
The transgenic plant or plant cell expressing the polypeptide or domain may be constructed in accordance with methods known in the art. In short, the plant or plant cell is constructed by incorporating one or more expression constructs encoding the polypeptide or domain into the plant host genome or chloroplast genome and propagating the resulting modified plant or plant cell into a transgenic plant or plant cell.
The present invention also relates to methods of producing a polypeptide(s) or domain of the present invention comprising (a) cultivating a transgenic plant or a plant cell comprising a polynucleotide encoding the polypeptide or domain under conditions conducive for production of the polypeptide or domain; and (b) recovering the polypeptide or domain.
The present invention also relates to a fermentation broth formulation comprising a polypeptide of the present invention. The fermentation broth product further comprises additional ingredients used in the fermentation process, such as, for example, cells (including, the host cells containing the gene encoding the polypeptide of the present invention which are used to produce the polypeptide of interest), cell debris, biomass, fermentation media and/or fermentation products. In some embodiments, the composition is a cell-killed fermentation broth containing organic acid(s), killed cells and/or cell debris, and culture medium.
The term “fermentation broth” as used herein refers to a preparation produced by cellular fermentation that undergoes no or minimal recovery and/or purification. For example, fermentation broths are produced when microbial cultures are grown to saturation, incubated under carbon-limiting conditions to allow protein synthesis (e.g., expression of enzymes by host cells) and secretion into cell culture medium. The fermentation broth can contain unfractionated or fractionated contents of the fermentation materials derived at the end of the fermentation. Typically, the fermentation broth is unfractionated and comprises the spent culture medium and cell debris present after the microbial cells (e.g., filamentous fungal cells) are removed, e.g., by centrifugation. In some embodiments, the fermentation broth contains spent cell culture medium, extracellular enzymes, and viable and/or nonviable microbial cells.
In an embodiment, the fermentation broth formulation and cell compositions comprise a first organic acid component comprising at least one 1-5 carbon organic acid and/or a salt thereof and a second organic acid component comprising at least one 6 or more carbon organic acid and/or a salt thereof. In a specific embodiment, the first organic acid component is acetic acid, formic acid, propionic acid, a salt thereof, or a mixture of two or more of the foregoing and the second organic acid component is benzoic acid, cyclohexanecarboxylic acid, 4-methylvaleric acid, phenylacetic acid, a salt thereof, or a mixture of two or more of the foregoing.
In one aspect, the composition contains an organic acid(s), and optionally further contains killed cells and/or cell debris. In one embodiment, the killed cells and/or cell debris are removed from a cell-killed fermentation broth to provide a composition that is free of these components.
The fermentation broth formulations or cell compositions may further comprise a preservative and/or anti-microbial (e.g., bacteriostatic) agent, including, but not limited to, sorbitol, sodium chloride, potassium sorbate, and others known in the art.
The cell-killed fermentation broth or composition may contain the unfractionated contents of the fermentation materials derived at the end of the fermentation. Typically, the cell-killed fermentation brothor composition contains the spent culture medium and cell debris present after the microbial cells (e.g., filamentous fungal cells) are grown to saturation, incubated under carbon-limiting conditions to allow protein synthesis. In some embodiments, the cell-killed fermentation broth or composition contains the spent cell culture medium, extracellular enzymes, and killed filamentous fungal cells. In some embodiments, the microbial cells present in the cell-killed fermentation broth or composition can be permeabilized and/or lysed using methods known in the art.
A fermentation broth as described herein is typically a liquid, but may contain insoluble components, such as killed cells, cell debris, culture media components, and/or insoluble enzyme(s). In some embodiments, insoluble components may be removed to provide a clarified liquid composition.
The fermentation broth formulations and cell compositions of the present invention may be produced by a method described in WO 90/15861 or WO 2010/096673.
The present invention also relates to compositions comprising a polypeptide(s) of the present invention. An embodiment is a cleaning or detergent composition comprising a beta-glucanase polypeptide of the invention and one or more amylases (and/or one or more proteases). Preferably, the compositions are enriched in such a polypeptide.

For example, amounts of 0.5 mg 1 mg, 1.5 mg, 2 mg or 2.5 mg enzyme protein/job can be used. The expression mg per job (mg/job) or mg/application refers to the amount of active substance used in relation to the total weight of the composition used for a complete cleaning cycle (which is to say in the case of detergent agents, the total amount of the cleaning agent used in a complete cleaning cycle of washing). In the case of preportioned cleaning agents, this information is the amount of the active substance in mg based on the total weight of the preportioned cleaning composition.
Said amounts are also applicable for each of the other individual enzyme proteins (e.g. amylase or protease) used in the dishwashing composition of the invention.
In some preferred embodiments, the detergent compositions provided herein are typically formulated such that, during use in aqueous cleaning operations, the wash water has a pH of from about 5.0 to about 13.5, or in alternative embodiments, even from about 6.0 to about 10.5, such as from about 5 to about 11, from about 5 to about 10, from about 5 to about 9, from about 5 to about 8, from about 5 to about 7, from about 6 to about 11, from about 6 to about 10, from about 6 to about 9, from about 6 to about 8, from about 6 to about 7, from about 7 to about 11, from about 7 to about 10, from about 7 to about 9, or from about 7 to about 8.

Alternatively, a detergent additive product comprising a beta-glucanase of the invention is suited for cleaning of a household dishwasher, e.g. from built-up residues on the filter and in the sump of the machines, preferably from residues containing beta-glucan-containing fibres. Such a machine-cleaning additive product may be suitable to clean at the same time from other residues like fat or limescale.

In embodiments in which cleaning and/or detergent components may not be compatible with the beta-glucanase of the present invention, suitable methods may be used for keeping the cleaning and/or detergent components and the beta-glucanase separated (i.e., not in contact with each other) until combination of the two components is appropriate. Such separation methods include any suitable method known in the art (e.g., gelcaps, encapsulation, tablets, and physical separation e.g., by use of a water dissolvable pouch having one or more compartments).
As mentioned when the beta-glucanase of the invention is employed as a component of a detergent composition (e.g., a laundry washing detergent composition, or a dishwashing detergent composition), it may, for example, be included in the detergent composition in the form of a non-dusting granulate, a stabilized liquid, or a protected enzyme.

Hydrotropes
A hydrotrope is a compound that solubilises hydrophobic compounds in aqueous solutions (or oppositely, polar substances in a non-polar environment). Typically, hydrotropes have both hydrophilic and a hydrophobic character (so-called amphiphilic properties as known from surfactants); however the molecular structure of hydrotropes generally do not favor spontaneous self-aggregation, see e.g. review by Hodgdon and Kaler (2007), Current Opinion in Colloid & Interface Science 12: 121-128. Hydrotropes do not display a critical concentration above which self-aggregation occurs as found for surfactants and lipids forming miceller, lamellar or other well defined meso-phases. Instead, many hydrotropes show a continuous-type aggregation process where the sizes of aggregates grow as concentration increases. However, many hydrotropes alter the phase behavior, stability, and colloidal properties of systems containing substances of polar and non-polar character, including mixtures of water, oil, surfactants, and polymers. Hydrotropes are classically used across industries from pharma, personal care, food, to technical applications. Use of hydrotropes in detergent compositions allow for example more concentrated formulations of surfactants (as in the process of compacting liquid detergents by removing water) without inducing undesired phenomena such as phase separation or high viscosity.
The detergent may contain 0-10% by weight, for example 0-5% by weight, such as about 0.5 to about 5%, or about 3% to about 5%, of a hydrotrope. Any hydrotrope known in the art for use in detergents may be utilized. Non-limiting examples of hydrotropes include sodium benzenesulfonate, sodium p-toluene sulfonate (STS), sodium xylene sulfonate (SXS), sodium cumene sulfonate (SCS), sodium cymene sulfonate, amine oxides, alcohols and polyglycolethers, sodium hydroxynaphthoate, sodium hydroxynaphthalene sulfonate, sodium ethylhexyl sulfate, and combinations thereof.
Builders and Co-Builders
The detergent composition may contain about 0-65% by weight, such as about 5% to about 50% of a detergent builder or co-builder, or a mixture thereof. In a dish wash detergent, the level of builder is typically 40-65%, particularly 50-65%. The builder and/or co-builder may particularly be a chelating agent that forms water-soluble complexes with Ca and Mg. Any builder and/or co-builder known in the art for use in detergents may be utilized. Non-limiting examples of builders include zeolites, diphosphates (pyrophosphates), triphosphates such as sodium triphosphate (STP or STPP), carbonates such as sodium carbonate, soluble silicates such as sodium metasilicate, layered silicates (e.g., SKS-6 from Hoechst), ethanolamines such as 2-aminoethan-1-ol (MEA), diethanolamine (DEA, also known as 2,2′-iminodiethan-1-ol), triethanolamine (TEA, also known as 2,2′,2″-nitrilotriethan-1-ol), and (carboxymethyl)inulin (CMI), and combinations thereof.

The detergent composition may include a co-builder alone, or in combination with a builder, for example a zeolite builder. Non-limiting examples of co-builders include homopolymers of polyacrylates or copolymers thereof, such as poly(acrylic acid) (PAA) or copoly(acrylic acid/maleic acid) (PAA/PMA).

In one embodiment, the builder or co-builder is a non-naturally occurring builder or co-builder.
Bleaching Systems
The detergent may contain 0-30% by weight, such as about 1% to about 20%, of a bleaching system. Any bleaching system known in the art for use in detergents may be utilized. Suitable bleaching system components include bleaching catalysts, photobleaches, bleach activators, sources of hydrogen peroxide such as sodium percarbonate, sodium perborates and hydrogen peroxide-urea (1:1), preformed peracids and mixtures thereof. Suitable preformed peracids include, but are not limited to, peroxycarboxylic acids and salts, diperoxydicarboxylic acids, perimidic acids and salts, peroxymonosulfuric acids and salts, for example, Oxone®, and mixtures thereof. Non-limiting examples of bleaching systems include peroxide-based bleaching systems, which may comprise, for example, an inorganic salt, including alkali metal salts such as sodium salts of perborate (usually mono- or tetra-hydrate), percarbonate, persulfate, perphosphate, persilicate salts, in combination with a peracid-forming bleach activator. The term bleach activator is meant herein as a compound which reacts with hydrogen peroxide to form a peracid via perhydrolysis. The peracid thus formed constitutes the activated bleach. Suitable bleach activators to be used herein include those belonging to the class of esters, amides, imides or anhydrides. Suitable examples are tetraacetylethylenediamine (TAED), sodium 4-[(3,5,5-trimethylhexanoyl)oxy]benzene-1-sulfonate (ISONOBS), 4-(dodecanoyloxy)benzene-1-sulfonate (LOBS), 4-(decanoyloxy)benzene-1-sulfonate, 4-(decanoyloxy)benzoate (DOBS or DOBA), 4-(nonanoyloxy)benzene-1-sulfonate (NOBS), and/or those disclosed in WO98/17767. A particular family of bleach activators of interest was disclosed in EP624154 and particulary preferred in that family is acetyl triethyl citrate (ATC). ATC or a short chain triglyceride like triacetin has the advantage that it is environmentally friendly Furthermore acetyl triethyl citrate and triacetin have good hydrolytical stability in the product upon storage and are efficient bleach activators. Finally ATC is multifunctional, as the citrate released in the perhydrolysis reaction may function as a builder. Alternatively, the bleaching system may comprise peroxyacids of, for example, the amide, imide, or sulfone type. The bleaching system may also comprise peracids such as 6-(phthalimido)peroxyhexanoic acid (PAP). The bleaching system may also include a bleach catalyst. In some embodiments the bleach component may be an organic catalyst selected from the group consisting of organic catalysts having the following formulae:
(iii) and mixtures thereof;
wherein each R1 is independently a branched alkyl group containing from 9 to 24 carbons or linear alkyl group containing from 11 to 24 carbons, preferably each R1 is independently a branched alkyl group containing from 9 to 18 carbons or linear alkyl group containing from 11 to 18 carbons, more preferably each R1 is independently selected from the group consisting of 2-propylheptyl, 2-butyloctyl, 2-pentylnonyl, 2-hexyldecyl, dodecyl, tetradecyl, hexadecyl, octadecyl, isononyl, isodecyl, isotridecyl and isopentadecyl.

Suitable photobleaches may for example be sulfonated zinc or aluminium phthalocyanines.
Preferably the bleach component comprises a source of peracid in addition to bleach catalyst, particularly organic bleach catalyst. The source of peracid may be selected from (a) pre-formed peracid; (b) percarbonate, perborate or persulfate salt (hydrogen peroxide source) preferably in combination with a bleach activator; and (c) perhydrolase enzyme and an ester for forming peracid in situ in the presence of water in a textile or hard surface treatment step.

Fabric Hueing Agents
The detergent compositions of the present invention may also include fabric hueing agents such as dyes or pigments, which when formulated in detergent compositions can deposit onto a fabric when said fabric is contacted with a wash liquor comprising said detergent compositions and thus altering the tint of said fabric through absorption/reflection of visible light.

The present invention is further described by the following examples that should not be construed as limiting the scope of the invention.
Detergent compositions used in the example sections as described herein included the following:
Automatic Mechanical Stress Assay (AMSA)
The wash performance in laundry washing is assessed using the Automatic Mechanical Stress Assay (AMSA). With the AMSA, the wash performance of a large quantity of small volume enzyme-detergent solutions can be examined. The AMSA plate has a number of slots for test solutions and a lid firmly squeezing the laundry sample, the textile to be washed against all the slot openings. During the washing time, the plate, test solutions, textile and lid are vigorously shaken to bring the test solution in contact with the textile and apply mechanical stress in a regular, periodic oscillating manner.
The wash performance is measured as the brightness of the colour of the textile washed. Brightness can also be expressed as the intensity of the light reflected from the sample when illuminated with white light. When the sample is stained the intensity of the reflected light is lower, than that of a clean sample. Therefore, the intensity of the reflected light can be used to measure wash performance.
Colour measurements are made with a professional flatbed scanner (Kodak iQsmart, Kodak, Midtager 29, DK-2605 Brøndby, Denmark), which is used to capture an image of the washed textile.
To extract a value for the light intensity from the scanned images, 24-bit pixel values from the image are converted into values for red, green and blue (RGB). The intensity value (Int) is calculated by adding the RGB values together as vectors and then taking the length of the resulting vector:
Int=√{square root over (r2+g2+b2)}
The experiments are conducted as described in the Automatic Mechanical Stress Assay (AMSA) for laundry method using a 1 cycle wash procedure and the experimental conditions specified in Table A.
Water hardness is adjusted by addition of CaCl2, MgCl2, and NaHCO3 to the test system. After washing the textiles are flushed in tap water and air-dried.
The terg-o-tometer is an industry standard. 1 L of wash solution is incubated in a water bath temperature controlled environment. The solution is mixed for 10 min before adding 1 L to each of the beakers. The temperature in the beakers is measured to be 20.0° C. The washed and rinsed swatches are left to dry overnight in a drying cabinet.
After washing and rinsing the swatches were spread out flat and allowed to air dry at room temperature overnight. Wash performance is expressed as a delta remission value (ΔRem). Light reflectance evaluations of the swatches are done using a Macbeth Color Eye 7000 reflectance spectrophotometer with large aperture. The measurements are made without UV in the incident light and remission at 460 nm was extracted. The dry swatches are measured with ColorEye 2. Measurement with small aperture through 2 layers (2 of the same type of swatch from the same beaker), 1 measurements on each swatch on the front side marked with beaker and swatch number. Remission values for individual swatches are calculated by subtracting the remission value of the control swatch from the remission value of the washed swatch. Calculating the enzyme effect is done by taking the measurements from washed swatches with enzymes and subtract with the measurements from washed without enzyme for each stain. The total enzyme performance is calculated as the average of individual ΔRemenzyme.
The Launder-O-Meter (LOM) is a medium scale model wash system that can be applied to test up to 20 different wash conditions simultaneously. A LOM is basically a large temperature controlled water bath with 20 closed metal beakers rotating inside it. Each beaker constitutes one small washing machine and during an experiment, each will contain a solution of a specific detergent/enzyme system to be tested along with the soiled and unsoiled fabrics it is tested on. Mechanical stress is achieved by the beakers being rotated in the water bath and by including metal balls in the beaker.
The LOM model wash system is mainly used in medium scale testing of detergents and enzymes at European wash conditions. In a LOM experiment, factors such as the ballast to soil ratio and the fabric to wash liquor ratio can be varied. Therefore, the LOM provides the link between small scale experiments, such as AMSA and mini-wash, and the more time consuming full scale experiments in front loader washing machines.
MiniLOM is a modified mini wash system of the Launder-O-Meter (LOM), which is a medium scale model wash system that can be applied to test up to 20 different wash conditions simultaneously.

In miniLOM, washes are performed in 50 ml test tubes placed in Stuart rotator.
AZCL-curdlan and AZCL-pachyman (azurine dye covalently cross-linked beta-glucans from Megazyme) assay are used for detection of endo-glucanase activity (laminarinase activity).
AZCL-curdlan or AZCL-pachyman (75 mg) was suspended in 15 mL detergent (Model detergents A, X, or ADW Model A). To 1 mL of this solution in Eppendorf tubes was added 100 μL enzyme (0.033 mg enzyme protein per millilLiter), incubated for 15 min at 40° C. while shaking at 1250 rpm in a pre-heated thermos-mixer and spun down for 2 min at 13200 rpm, diluted 5 or 10 times with a 5% Triton-X-100 including 10 μM CaCl2 and 250 μL of the solution was transferred to a micro-titer plate and the sample absorbance was measured at 590 nm.
The alpha-amylase activity may be determined by a method employing the G7-pNP substrate. G7-pNP which is an abbreviation for 4,6-ethylidene(G7)-p-nitrophenyl(G1)-α,D-maltoheptaoside, a blocked oligosaccharide which can be cleaved by an endo-amylase, such as an alpha-amylase. Following the cleavage, the alpha-Glucosidase included in the kit digest the hydrolysed substrate further to liberate a free PNP molecule which has a yellow color and thus can be measured by visible spectophometry at λ=405 nm (400-420 nm). Kits containing G7-pNP substrate and alpha-Glucosidase is manufactured by Roche/Hitachi (cat. No. 11876473). The G7-pNP substrate from this kit contains 22 mM 4,6-ethylidene-G7-pNP and 52.4 mM HEPES (2-[4-(2-hydroxyethyl)-1-piperazinyl]-ethanesulfonic acid), pH 7.0). The alpha-Glucosidase reagent contains 52.4 mM HEPES, 87 mM NaCl, 12.6 mM MgCl2, 0.075 mM CaCl2, ≥4 kU/L alpha-glucosidase). The substrate working solution is made by mixing 1 mL of the alpha-Glucosidase reagent with 0.2 mL of the G7-pNP substrate. This substrate working solution is made immediately before use. Dilution buffer: 50 mM MOPS, 0.05% (w/v) Triton X100 (polyethylene glycol p-(1,1,3,3-tetramethylbutyl)-phenyl ether (C14H22O(C2H4O), (n=9-10))), 1 mM CaCl2), pH8.0. The amylase sample to be analyzed is diluted in dilution buffer to ensure the pH in the diluted sample is 7. The assay is performed by transferring 20 μl diluted enzyme samples to 96 well microtiter plate and adding 80 μl substrate working solution. The solution is mixed and pre-incubated 1 minute at room temperature and absorption is measured every 20 sec. over 5 minutes at OD 405 nm. The slope (absorbance per minute) of the time dependent absorption-curve is directly proportional to the specific activity (activity per mg enzyme) of the alpha-amylase in question under the given set of conditions. The amylase sample should be diluted to a level where the slope is below 0.4 absorbance units per minute.
An AZCL-He-cellulose (azurine dye covalently cross-linked cellulose) assay is used for detection of cellulase (endo-glucanase) activity. AZCL-He-cellulose (75 mg) is suspended in 15 mL detergent (e.g. Model detergent A). To 1 mL of this solution in Eppendorf tubes is added 100 μL enzyme (0.09 mg enzyme protein/mL), incubated for 15 min at 40° C. while shaking at 1250 rpm in a pre-heated thermo mixer and spun down for 2 min at 13200 rpm. 250 μL of the solution is transferred to a micro-titer plate and the sample absorbance is measured at 590 nm.
DNase activity is determined on DNase Test Agar with Methyl Green (BD, Franklin Lakes, N.J., USA), which is prepared according to the manual from supplier. Briefly, 21 g of agar is dissolved in 500 ml water and then autoclaved for 15 min at 121° C. Autoclaved agar is temperated to 48° C. in water bath, and 20 ml of agar is poured into petri dishes with and allowed to solidify by incubation o/n at room temperature. On solidified agar plates, 5 μl of enzyme solutions are added and DNase activity is observed as colorless zones around the spotted enzyme solutions.
DNase activity is determined by using the DNaseAlert™ Kit (11-02-01-04, IDT Intergrated DNA Technologies) according to the supplier's manual. Briefly, 95 μl DNase sample is mixed with 5 μl substrate in a microtiter plate, and fluorescence is immediately measured using a Clariostar microtiter reader from BMG Labtech (536 nm excitation, 556 nm emission).
Lipase is diluted with a buffer (10 mM Succinic acid+2 mM CaCl2)+0.02% Brij 35 adjusted to pH6.5) to the specified concentration. 10 uL of the 100 ppm lipase solution is added to a 90 uL of detergent composition, stirred for 5 minutes and sealed. Samples are stored at 4° C. in detergent D002 (unstressed) and in detergent D002 at 47° C. (stressed). Storage time is 335.5 hours. After storage possible condensation liquid is collected by centrifugation. To the 100 uL stressed or unstressed sample 235 uL of buffer (0.1M Tris-HCl, 9 mM CaCl2), 0.0225% Brij-30, pH8.0+0.85% 4-FBPA (31.5 g/l)) are added corresponding to a 3.35-fold dilution. After 10 minutes stirring 5 uL sample aliquots are further diluted with the same buffer 60-fold. Then one part of this lipase dilution is mixed with four parts of 0.5 mM pNP-palmitate, 1 mM calcium chloride, 100 mM Tris (pH8.0), 6.5 mM Deoxycholate, 1.4 g/L AOS and for 30 minutes release of the pNP chromophore is measured spectrophotometrically. This is used to determine activity via the initial linear slope of the reaction. Residual activity is calculated as the ratio of the measured velocities of stressed versus unstressed sample. The median value of the residual activity is calculated based on four replicates and normalized by a lipase variant reference run with each experimental set.
Mannanase activity may be tested according to standard test procedures known in the art, such as by applying a solution to be tested to 4 mm diameter holes punched out in agar plates containing 0.2% AZCL galactomannan (carob), i.e. substrate for the assay of endo-1,4-beta-D-mannanase available as CatNo. I-AZGMA from the company Megazyme (available on the Internet at megazyme.com/purchase/index.html).
Microtiter Assay for Quantification of Pectate Lyase Activity
Pectate lyase cleaves polygalacturonic acid through a trans elimination mechanism. This means that it leaves a double C—C bond for each substrate split. This bond absorbs at 235 nm allowing direct detection of pectate lyase action on soluble polygalacturonic acid by measuring absorbance at that wavelength.
An enzyme sample is diluted in assay buffer (100 mM Tris-HCl, 0.68 mM CaCl2, pH 8.0) to a concentration between 5 and 100 ng/ml. If the enzyme sample contains detergent it should be diluted at least a 1000-fold with respect to detergent. 100 μl of the enzyme buffer dilution is mixed with 100 μl substrate (1% (w/v) polygalacturonic acid, e.g., P-3850 from Sigma, stirred in assay buffer for at least 15 min and centrifuged for 5 min at 2300 g, supernatant is used) in a heating plate and heated to 40° C. for 10 min in a heating block, preferably a PCR machine or equipment of equivalent accuracy and heating speeds.
100 μl enzyme/substrate solution is mixed with 100 μl stop reagent (50 mM H3PO4) in a UV-transparent microtiter plate. The UV plate is shaken briefly and gently, and the absorbance at 235 nm is measured in a microtiter spectrometer (e.g., Molecular Devices, SpectraMAX 190). The absorbance readings are corrected for background absorbance by subtracting the absorbance of a control sample, run without enzyme added, to all measured values.
Alternatively, catalytic activity of pectate lyase can be determined by the viscosity assay, APSU.
Viscosity Assay, APSU
APSU units: The APSU assay measures the change in viscosity of a solution of polygalacturonic acid in the absence of added calcium ions. A 5% w/v solution of sodium polygalacturonate (e.g., Sigma P-1879) is solubilised in 0.1 M glycine buffer, pH 10.4 ml of this solution are preincubated for 5 min at 40° C. Then, 250 microlitre of the enzyme (or enzyme dilution) are added, after which the reaction is mixed for 10 sec on a mixer at the highest speed and incubated for 20 min at 40° C. or at another temperature.
Proteolytic activity can be determined by a method employing Suc-AAPF-PNA as the substrate. Suc-AAPF-PNA is an abbreviation for N-Succinyl-Alanine-Alanine-Proline-Phenylalanine-p-Nitroanilide and is a blocked peptide which can be cleaved by endo-proteases. Following cleavage, a free PNA molecule is liberated, which has a yellow color and thus can be measured by visible spectrophotometry at wavelength 405 nm. The Suc-AAPF-PNA substrate is manufactured by Bachem (cat. no. L1400, dissolved in DMSO). The protease sample to be analyzed is diluted in residual activity buffer (100 mM Tris pH 8.6). The assay is performed by transferring 3 0 μl of diluted enzyme samples to 96 well microtiter plate and adding 70 μl substrate working solution (0.72 mg/ml in 100 mM Tris pH8.6). The solution is mixed at room temperature and absorption is measured every 20 seconds over 5 minutes at OD 405 nm. The slope (absorbance per minute) of the time dependent absorption-curve is directly proportional to the activity of the protease in question under the given set of conditions. The protease sample is diluted to a level where the slope is linear.
The beta-glucanases were derived from bacterial strains isolated from environmental soil samples by standard microbiological isolation techniques. The isolated pure strains were identified and taxonomy was assigned based on DNA sequencing of the 16S ribosomal gene (Table 1).

Chromosomal DNA was isolated from pure culture with the DNeasy Blood & Tissue Kit from Qiagen (Hilden, Germany) and subjected to full genome sequencing using Illumina technology. Genome sequencing, the subsequent assembly of sequencing reads and the gene discovery (i.e. annotation of gene functions) is known to the person skilled in the art and the service can be purchased commercially.
The genome sequence was analyzed for putative beta-glucanases from the Carbohydrate Active Enzymes database (CAZY) family GH16 (Lombard V et al. 2014. Nucleic Acids Res 42:D490-D495) and this analysis identified six genes encoding a putative beta-glucanase enzymes which were subsequently cloned and recombinantly expressed in Bacillus subtilis.
The genes encoding the beta-glucanases were amplified as single amplicons by PCR and fused with regulatory elements, an affinity purification tag and homology regions for recombination into the pectate lyase locus of the B. subtilis genome.
The linear integration construct was a SOE-PCR fusion product (Horton, R. M., Hunt, H. D., Ho, S. N., Pullen, J. K. and Pease, L. R. (1989) Engineering hybrid genes without the use of restriction enzymes, gene splicing by overlap extension Gene 77: 61-68) made by fusion of the gene between two B. subtilis chromosomal regions along with strong promoters and a chloramphenicol resistance marker. The SOE-PCR method is also described in patent application WO 2003095658.
The genes were expressed under the control of a triple promoter system (as described in WO 99/43835), consisting of the promoters from Bacillus licheniformis alpha-amylase gene (amyL), Bacillus amyloliquefaciens alpha-amylase gene (amyQ), and the Bacillus thuringiensis cryIIIA promoter including stabilizing sequence.
The genes were fused with DNA encoding a Bacillus clausii secretion signal (encoding the following amino acid sequence: MKKPLGKIVASTALLISVAFSSSIASA (SEQ ID NO: 19) replacing the native secretion signal. Furthermore, the expression construct results in the addition of a amino-terminal poly histidine tail consisting of the amino acid sequence HHHHHHPR(SEQ ID NO: 20) to the mature beta-glucanase.
The SOE-PCR product was transformed into Bacillus subtilis and integrated in the chromosome by homologous recombination into the pectate lyase locus. Subsequently a recombinant Bacillus subtilis clone containing the integrated expression construct was grown in liquid culture. The culture broth was centrifuged (20000×g, 20 min) and the supernatant was carefully decanted from the precipitate and used for purification of the enzyme or alternatively sterile filtered supernatant was used directly for assays.
The pH of the cleared supernatant was adjusted to pH 8, filtrated through a 0.2 μM filter, and the supernatants applied to a 5 ml HisTrap™ excel column. Prior to loading, the column had been equilibrated in 5 column volumes (CV) of 50 mM Tris/HCl pH 8. In order to remove unbound material, the column was washed with 8 CV of 50 mM Tris/HCl pH 8, and elution of the target was obtained with 50 mM HEPES pH 7+10 mM imidazole. The eluted protein was desalted on a HiPrep™ 26/10 desalting column, equilibrated using 3 CV of 50 mM HEPES pH 7+100 mM NaCl. This buffer was also used for elution of the target, and the flow rate was 10 ml/min. Relevant fractions were selected and pooled based on the chromatogram and SDS-PAGE analysis.
A phylogenetic tree was constructed with polypeptide sequences containing a GH16 domain, as defined in the CAZY database (Carbohydrate-active enzymes database (CAZy) in 2013. Nucleic Acids Res 42:D490-D495. Lombard et al.). The phylogenetic tree was constructed from a multiple alignment of mature polypeptide sequences containing at least one GH16 domain. The sequences were aligned using the MUSCLE algorithm version 3.8.31 (Edgar, 2004. Nucleic Acids Research 32(5): 1792-1797), and the trees were constructed using FastTree version 2.1.8 (Price et al., 2010, PloS one 5(3)) and visualized using iTOL (Letunic & Bork, 2007. Bioinformatics 23(1): 127-128).
The polypeptides in the GH16 glycoside hydrolase family can be separated into multiple distinct sub-clusters or clades when visualized as a phylogenetic tree and the clades can be observed to contain polypeptides encoding enzyme with different enzymatic specificities both within beta-glucan active enzymes and outside.
Mapping of the experimentally the verified laminarinase polypeptides express in Example 2 onto the phylogenetic tree allows the elucidation of a laminarinase specific clade of polypeptides and the determination of specific motifs associated with the clade.
Identification of a Laminarinase Clade from the Order Bacillales.
The clade comprises GH16 glycoside hydrolase family polypeptides of bacterial origin from the order Bacillales having laminarinase activity and comprising the conserved polypeptide motifs GEXDXME (SEQ ID NO: 28), GXGNXEXXXY (SEQ ID NO: 29), NXAXGG (SEQ ID NO: 30) and YTS[GA][KR] where X denotes any natural amino acid and residues in bracket [GA] means either G or A and [KR] means either K or R.
The 3D structure of a laminarinase from the bacteria Thermotoga maritima (SEQ ID NO: 27) has been experimentally determined. (Crystal structures of the laminarinase catalytic domain from Thermotoga maritima MSB8 in complex with inhibitors: essential residues for ß-1,3- and ß-1,4-glucan selection. Jeng et al. J Biol Chem. 2011 Dec. 30; 286(52):45030-40).
Based on this structure and multiple alignments of the polypeptide sequences from SEQ ID NO: 27 and the experimental laminarinases from Example 2 one can on the basis of sequence homology deduce that the two glutamic acid (E) residues of the GEXDXME (SEQ ID NO: 28) are analogous to residues E132 and E137 of SEQ ID NO: 27 which are directly involved as catalytic residues and are essential for catalysis.
The asparagine (N) and glutamic acid (E) residues in the GXGNXEXXXY (SEQ ID NO: 29) motif are analogous to residue N45 and E47 in SEQ ID NO: 27 which may form direct or water-mediated hydrogen bonds to the laminarin substrate aiding in positioning the substrate correctly in the catalytic groove of the enzyme.
The asparagine residue (N) in the NXAXGG (SEQ ID NO: 30) motif is analogous to the N225 residue in SEQ ID NO: 27 which is suggested to have a role in substrate binding.
The arginine or lysine in the YTS[GA][KR] motif carry a positive charge and, without being bound by theory, this charge is proposed to be important for correct substrate interaction either through direct or water mediated interaction and is analogous to the R85 residue of the SEQ ID NO: 27.
In this example, enzymatic activity were measured on AZCL-curdlan and AZCI-pachyman substrate in detergents thus modeling various laundry, automatic dish wash and hand dish wash conditions. Measurements of enzymatic activity were carried out as described in Example 1, using the dilution factor as noted.

I. Reducing End Method Description:
Laminarin (from Sigma-Aldrich) or Yeast barley beta-glucan from Megazyme (100 mg) was suspended in 100 mL detergent (Model detergents A, X or ADW Model A), heated to 70° C. and stirred overnight. To 1 mL of this solution in Eppendorf tubes was added 25 μL enzyme (0.5 mg enzyme protein per milliliter), incubated for 60 min at 37° C. while shaking at 1250 rpm in a pre-heated thermos-mixer and stored on ice. 50 μL of the incubated sample was transferred to Eppendorf tubes and 250 μL PAHBAH-reagent mixture (Reagent A: 100 μL+Reagent B: 900 μL—see descriptions below) was added and incubated for 6 min at 60° C. in thermo-mixer. Then placed on ice for 3 min, followed by 3 min at room temperature. Then 150 μL of the solution was transferred to a micro-titer plate and the sample absorbance was measured at 410 nm, either measured directly or diluted 2 or 3 times with a 5% Triton-X-100 including 10 μM CaCl2. Reagent A: To MilliQ water (6 mL) was added p-hydroxy benzoic acid hydrate (PAHBAH, 1 g), then HCl-solution (3 mL, 4M) and then MilliQ water was added up to 20 mL.
Reagent B: To MilliQ water (50 mL) was added trisodium citrate (2.49 g), CaCl2, 2H2O (0.268 g), sodium hydroxide (0.268 g) and then MilliQ water was added up to 200 mL.

The substrate specificities of beta-glucanases were further tested using various assays (AZCL-curdlan, AZCL-pachyman (azurine dye covalently cross-linked beta-glucan from Megazyme), laminarin (from Sigma-Aldrich) and yeast beta-glucan (from Megazyme), generally following the protocol as described in Example 1 and Example 5, above.
In this example substrate specificity of the beta-glucanases of the invention were tested on various substrates. Based on this substrate specificity, it is concluded that the beta-glucanases of the present invention have laminarinase enzymatic activity.
*1No/very little activity of Bacillus species B was shown on this substrate under the tested conditions.
In addition, NMR analyses (data not shown) were performed of the Bacillus species B, Paenibacillus sp, Thermobacillus sp, Cohnella sp, Paenibacillus elgii, and Bacillus species A beta-glucanases according to the invention and their degradation of mixed linkage (1,3;1,4) beta-glucan. All except for Bacillus species B act on the substrates, whereas Bacillus species B only reacts a little. Based on this, we conclude that Bacillus species B can be classified as EC 3.2.1.39, whereas the other five enzymes can be classified as EC 3.2.1.6.
I. Wascator Bottle Wash Method Description:
A Wascator bottle wash method was used to detect the performance of the enzymes. In a Wascator washing machine (FOM 71 Lab) bottles (60 mL, DSE PP 70X35 Aseptisk, material No.: 216-2620, from VWR) with 25 mL detergent solution including enzyme(s) and four stains (035KC Chocolate porridge oat from Equest, 2 cm in diameter) were added. Two kg ballast (tea towels, cotton) was included in the washing machine. Washed in 25 L water for 20 min at 29° C. in liquid model detergent for laundry (model detergent A). After wash the stains were rinsed with tap water twice (3 L) and dried overnight at rt (room temperature) in drying cabinet (Electrolux, Intuition, EDD2400). The remission was measured on a spectrophotometer (Macbeth Color-Eye 7000 Remissions) at 460 nm.
II. Results:
In this example the results of combining the individual laminarinases with an alpha-amylase (SEQ ID NO: 45) were studied in order to investigate a potential synergistic effect between the two enzymes using the Wascator bottle wash method, in the presence of 0.1 mg enzyme protein per liter of laminarinase and 0.1 mg enzyme protein per liter of alpha-amylase (SEQ ID NO: 45) at 29° C. The detailed conditions used in this example are described in Table 9 below and the results are shown in Table 10 below.

Red Clay Procedure in Terg-O-Tometer (TOM) Wash Assay
The Tergo-To-Meter (TOM) is a medium scale model wash system that can be applied to test 16 different wash conditions simultaneously. A TOM is basically a large temperature controlled water bath with up to 16 open metal beakers submerged into it. Each beaker constitutes one small top loader style washing machine and during an experiment, each of them will contain a solution of a specific detergent/enzyme system and the soiled and unsoiled fabrics its performance is tested on. Mechanical stress is achieved by a rotating stirring arm, which stirs the liquid within each beaker. Because the TOM beakers have no lid, it is possible to withdraw samples during a TOM experiment and assay for information on-line during wash.
The TOM model wash system is mainly used in medium scale testing of detergents and enzymes at US or LA/AP wash conditions. In a TOM experiment, factors such as the ballast to soil ratio and the fabric to wash liquor ratio can be varied. Therefore, the TOM provides the link between small scale experiments, such as AMSA and mini-wash, and the more time consuming full scale experiments in top loader washing machines.
The swatches include a combination of food and technical stains.
The above commercial test materials are purchased from Warwick Equest Ltd, Unit 55, Consett Business Park, Consett, County Durham, DH8 6BN, United Kingdom, 5 cm in diameter.
