This application contains a Sequence Listing in computer readable form. The computer readable form is incorporated herein by reference.
The present invention relates to detergents for laundry. In particular the invention relates to the use of carbohydrate binding modules to provide an anti-wrinkle effect to textile.
Laundering of textiles is common activities in normal household activities. When clothes have been used it is typically laundered in order to remove dirt and refresh the clothes before it is used again. Most used laundry processes involved washing in an aqueous detergent solution followed by one or more rinses and subsequent drying.
However, it is also commonly experienced that clothes and textiles becomes wrinkled during laundry, and the washed clothes get a wrinkled, less appealing appearance.
It is desirable to reduce the amount of wrinkles formed during laundry of clothes or textiles.
The invention relates to the use of a polypeptide having carbohydrate binding activity for reducing wrinkles and/or providing increased anti-crease properties and/or providing improved ease of ironing and/or providing improved shape retention in a cleaning process of a fabric or textile.
The polypeptide having carbohydrate binding activity is preferably selected among polypeptides known as Carbohydrate binding Modules (CBM) or mixtures thereof.
The invention also relates to a detergent compositions, as well as laundry booster compositions comprising a polypeptide having carbohydrate binding activity.
As used herein, the singular forms “a”, “an”, and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.
Anti-wrinkle and anti-crease and reducing wrinkle and wrinkle reduction: In the context of the present invention, the terms “crease” and “wrinkle” and related terms, such as “anti-crease,” “anti-wrinkle,” “reducing wrinkle,” and “wrinkle reduction” refer to non-permanent deformations in fabrics, such as fabrics and textiles which can be removed by flattening at elevated temperature and moisture (e.g. by ironing). The terms are used interchangeably herein.
Bacterial: In the context of the present invention, the term “bacterial” in relation to poly-peptide or carbohydrate binding module refers to a polypeptide encoded by and thus directly derivable from the genome of a bacteria, where such bacteria has not been genetically modified to encode said polypeptide, e.g. by introducing the encoding sequence in the genome by recombinant DNA technology. In the context of the present invention, the term “bacterial carbohydrate binding module” or “carbohydrate binding module obtained from a bacterial source” or “polypeptide is of bacterial origin” thus refers to a polypeptide encoded by and thus directly derivable from the genome of a bacterial species, where the bacterial species has not been subjected to a genetic modification introducing recombinant DNA encoding said polypeptide. Thus, the nucleotide sequence encoding the bacterial polypeptide is a sequence naturally in the genetic background of a bacterial species. A sequence encoding a bacterial polypeptide may also be referred to a wildtype (or parent). The bacterial polypeptide e.g. bacterial carbohydrate binding module also includes naturally occurring polypeptides modified by, e.g., truncation to obtain the portion of the molecule of interest. A bacterial polypeptide includes recombinant produced wild types, as well as synthetically produced peptides. In a further aspect, the invention provides polypeptides substantially homologous to a bacterial polypeptide. In the context of the present invention, the term “substantially homologous” denotes a polypeptide having carbohydrate binding activity which is at least 80%, preferably at least 85%, more preferably at least 90%, more preferably at least 95%, even more preferably at least 96%, 97%, 98%, and most preferably at least 99% identical to the amino acid sequence of a selected bacterial polypeptide.
Carbohydrate binding module: The term “carbohydrate binding module” as used herein refers to the is independent portion of a polypeptide having a contiguous amino acid sequence with a discreet fold and carbohydrate-binding activity. See, e.g., cazy.org/Carbohydrate-Binding-Modules. While CBMs are often naturally occurring within larger enzymes (typically connected via a linker region to one or more catalytic domains), the term as used herein refers to the independent module. A CBM in its naturally occurring form may be located at the N-terminus, C-terminus, or at an internal position of a polypeptide, and as used herein may be a truncation of its naturally occurring form.
Exemplary CBM families useful according to the invention are those of CBM family 1, 4, 17, 28, 30, 44, 72 and 79. Again, with reference to cazy.org/Carbohydrate-Binding-Modules, CBM Family 1 includes modules of approximately 40 residues found almost exclusively in fungi. The cellulose-binding function has been demonstrated in many cases, and appears to be mediated by three aromatic residues separated by about 10.4 angstrom and which form a flat surface. CBM family 4 includes modules of approximately 150 residues found in bacterial enzymes. Binding of these modules has been demonstrated with xylan, beta-1,3-glucan, beta-1,3-1,4-glucan, beta-1,6-glucan and amorphous cellulose but not with crystalline cellulose. CBM family 17 includes modules of approximately 200 residues. Binding to amorphous cellulose, cellooligosaccharides and derivatized cellulose has been demonstrated. Regarding CBM family 28, the module from the endo-1,4-glucanase of Bacillus sp. 1139 binds to non-crystalline cellulose, cellooligosaccharides, and β-(1,3)(1,4)-glucans. For CBM Family 30, binding to cellulose has been demonstrated for the N-terminal module of Fibrobacter succinogenes CeIF. The C-terminal CBM44 module of the Clostridium thermocellum enzyme has been demonstrated to bind equally well cellulose and xyloglucan. CBM Family 72 includes modules of 130-180 residues found at the C-terminus glycoside hydrolases from various families, sometimes as tandem repeats. The CBM72 found on an endoglucanase from an uncultivated microorganism was found to bind a broad spectrum of polysaccharides including soluble and insoluble cellulose, beta-1,3/1,4-mixed linked glucans, xylan, and beta-mannan. CBM Family 79 includes modules of approx. 130 residues found so far only in ruminococcal proteins. Binding to various beta-glucans was shown for the R. flavefaciens GH9 enzyme.
In a preferred embodiment, the carbohydrate binding module is not attached to (linked to) a softening protein.
As used herein “mixture” or “mixtures” of CBM include blends of polypeptides that are otherwise independently identified, as well as naturally occurring or synthetic constructs of polypeptides. For example, the CBMs useful herein may be present in the former of dimers, trimers, tetramers, and other higher order fusion products, either homologous or heterologous, which may optionally further comprise one or more amino acid linker sequences joining the one or more CBMs.

Coating or reincorporation or smoothing of protruding or broken fibers is also termed anti-pilling. Prevention of or reduction of a decrease in dimensional size is termed anti-shrinkage. Prevention of or repair of abrasion is termed anti-wear. Prevention of wrinkles, recovery of textile from wrinkling, smoothness of seams, and/or retention of creases after repeated home laundering is termed “anti-wrinkle” or anti-crease. Improvement of the textile-softness or reduction of textile stiffness is termed improved fabric softness. Color clarification of a textile, or enhanced colorfastness to laundering, perspiration, light, chlorine and non-chlorine bleach, heat, or light at high temperature is termed improved color appearance. Resistance to dimensional size change or dimensional size change during home laundering is termed improved shape retention. Elevated combustion temperature or resistance to burning or melting at high temperatures is termed flame resistance. Resistance to chemical reactions, solubilization or degradation in the presence of chemical solvents, acid or alkali is termed chemical resistance. Resistance to adsorption or prevention of the retention of odorous compounds, particularly short chain fatty acids or low vapor pressure organic compounds is termed anti-odor. Opacity to and prevention or repair of oxidative damage caused by UV irradiation is termed anti-UV. Decreased retention of water, or resistance to wetting is termed water repellency. Enhanced microbiostatic or microbiocidal properties are termed antimicrobial. An increase in resistance to induced electrostatic charge of a textile, or increase in decay rate of an induced electrostatic charge in a textile is termed improved static control. Resistance to elongation under force or augmentation of breaking force is termed improved tensile strength.
First-wash: The term “first-wash” means showing improvement or performance benefit effect already during or in the first wash, and is not dependent on one or more subsequent wash step or wash and dry steps in order to achieve the benefit.
Fungal: In the context of the present invention the term “fungal” in relation to polypeptide or carbohydrate binding module refers to a polypeptide encoded by and thus directly derivable from the genome of a fungus, where such fungus has not been genetically modified to encode said polypeptide, e.g. by introducing the encoding sequence in the genome by recombinant DNA technology. In the context of the present invention, the term “fungal carbohydrate binding module” or “carbohydrate binding module obtained from a fungal source” or “polypeptide is of fungal origin” thus refers to a polypeptide encoded by and thus directly derivable from the genome of a fungal species, where the fungal species has not been subjected to a genetic modification introducing recombinant DNA encoding said polypeptide. Thus, the nucleotide sequence encoding the fungal polypeptide may be a sequence naturally in the genetic background of a fungal species. A sequence encoding a fungal polypeptide may also be referred to a wildtype (or parent). The fungal polypeptide e.g. fungal carbohydrate binding module also includes naturally occurring polypeptides modified by, e.g., truncation to obtain the portion of the molecule of interest. A fungal polypeptide includes recombinant produced wild types, as well as synthetically produced peptides. In a further aspect, the invention provides polypeptides substantially homologous to a fungal polypeptide.

Laundering: The term “laundering” relates to both household laundering and industrial laundering and means the process of treating textiles with a solution containing a cleaning or detergent composition of the present invention. The laundering process can for example be carried out using e.g. a household or an industrial washing machine or can be carried out by hand.
Laundry booster: A laundry booster is an additive used to increase the efficacy of a main wash detergent composition.
Sequence identity: The relatedness between two amino acid sequences or between two nucleotide sequences is described by the parameter “sequence identity”. For purposes of the present invention, the sequence identity between two amino acid sequences may be determined using the Needleman-Wunsch algorithm (Needleman and Wunsch, 1970, J. Mol. Biol. 48: 443-453) as implemented in the Needle program of the EMBOSS package (EMBOSS: The European Molecular Biology Open Software Suite, Rice et al., 2000, Trends Genet. 16: 276-277), preferably version 5.0.0 or later. The parameters used are gap open penalty of 10, gap extension penalty of 0.5, and the EBLOSUM62 (EMBOSS version of BLOSUM62) substitution matrix. The output of Needle labeled “longest identity” (obtained using the—nobrief option) is used as the percent identity and is calculated as follows:
(Identical Residues×100)/(Length of Alignment−Total Number of Gaps in Alignment)

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.
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 laundry 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 also contain 0-50% by weight, such as about 5% to about 30%, of a detergent co-builder. The detergent composition may include a co-builder alone, or in combination with a builder, for example a zeolite builder.

The enzyme of the invention may be formulated as a granule for example as a co-granule that combines one or more enzymes. Each enzyme will then be present in more granules securing a more uniform distribution of enzymes in the detergent. This also reduces the physical segregation of different enzymes due to different particle sizes. Methods for producing multi-enzyme cogranulates for the detergent industry are disclosed in the IP.com disclosure IPCOM000200739D.
Another example of formulation of enzymes by the use of co-granulates are disclosed in WO 2013/188331, which relates to a detergent composition comprising (a) a multi-enzyme cogranule; (b) less than 10 wt zeolite (anhydrous basis); and (c) less than 10 wt phosphate salt (anhydrous basis), wherein said enzyme co-granule comprises from 10 to 98 wt % moisture sink component and the composition additionally comprises from 20 to 80 wt % detergent moisture sink component.

The multi-enzyme co-granule may comprise an enzyme of the invention and (a) one or more enzymes selected from the group consisting of first-wash lipases, cleaning cellulases, xyloglucanases, perhydrolases, peroxidases, lipoxygenases, laccases and mixtures thereof; and (b) one or more enzymes selected from the group consisting of hemicellulases, proteases, care cellulases, cellobiose dehydrogenases, xylanases, phospho lipases, esterases, cutinases, pectinases, mannanases, pectate lyases, keratinases, reductases, oxidases, phenoloxidases, ligninases, pullulanases, tannases, pentosanases, lichenases glucanases, arabinosidases, hyaluronidase, chondroitinase, amylases, nucleases, and mixtures thereof. In another embodiment, the multi-enzyme co-granule does not comprise a cellulase.
The polypeptides of the present invention may be added to and thus become a component of a detergent composition.
The detergent composition of the present invention may be formulated, for example, as a hand or machine laundry detergent composition including a laundry additive composition suitable for pre-treatment of stained fabrics and a rinse added fabric softener composition, or be formulated as a detergent composition for use in general household hard surface cleaning operations, or be formulated for hand or machine dishwashing operations.

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. A LOM or is basically a large temperature controlled water bath with 20 closed metal beakers rotating inside it.

In miniLOM, washes are performed in 50 ml test tubes placed in Stuart rotator.
The Terg-O-tometer (TOM) is a medium scale model wash system that can be applied to test 12 different wash conditions simultaneously. A TOM is basically a large temperature controlled water bath with up to 12 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, as well as for EU 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 and the more time consuming full scale experiments in top loader washing machines.
Expression constructs were constructed by preparing a shuttle plasmid comprising the nucleotide sequence encoding the CBM in operation connection with an Aspergillus promoter, signal sequence and Kex cleavage site and terminator, and further comprising an amdS gene for amdS selection in Aspergillus. The promoter used for the CBM production is further described in WO2003/008575. The correctness of the constructs was confirmed by sequencing.
