TECHNICAL FIELD

The present disclosure relates to a detergent composition, such as laundry compositions and dish wash compositions, including hand wash and automatic dish wash compositions, comprising xanthan lyase or endoglucanase or mixtures thereof and at least one enzyme stabilizing component, in order to improve at least one or more properties including detergent stability (e.g. improved stability in a detergent composition) and/or storage stability (e.g. improved storage stability in a detergent composition). The disclosure also relates to methods for producing and using such compositions as well as to the use of specific enzyme stabilizing components for improving storage stability of xanthan lyase or endoglucanase or mixtures thereof. The variants described herein are particularly suitable for use in cleaning processes and detergent compositions, in particular laundry detergents.

BACKGROUND

Xanthan gum is a polysaccharide derived from the bacterial coat of Xanthomonas campestris. It is produced by the fermentation of glucose, sucrose, or lactose by the Xanthomonas campestris bacterium. After a fermentation period, the polysaccharide is precipitated from a growth medium with isopropyl alcohol, dried, and ground into a fine powder. Later, it is added to a liquid medium to form the gum. Xanthan gum is a natural polysaccharide consisting of different sugars which are connected by several different bonds, such as β-D-mannosyl-β-D-1,4-glucuronosyl bonds and β-D-glucosyl-β-D-1,4-glucosyl bonds. Xanthan gum is at least partly soluble in water and forms highly viscous solutions or gels. Complete enzymatic degradation of xanthan gum requires several enzymatic activities including xanthan lyase activity and endo-β-1,4-glucanase activity. Xanthan lyases are enzymes that cleave the β-D-mannosyl-β-D-1,4-glucuronosyl bond of xanthan and have been described in the literature. Xanthan lyases are known in the art, e.g. two xanthan lyases have been isolated from Paenibacillus alginolyticus XL-1 (e.g. Ruijssenaars et al. (1999) ‘A pyruvated mannose-specific xanthan lyase involved in xanthan degradation by Paenibacillus alginolyticus XL-1’, Appl. Environ. Microbiol. 65(6): 2446-2452, and Ruijssenaars et al. (2000), ‘A novel gene encoding xanthan lyase of Paenibacillus alginolyticus strain XL-1’, Appl. Environ. Microbiol. 66(9): 3945-3950).

Glycoside hydrolases are enzymes that catalyze the hydrolysis of the glycosyl bond to release smaller sugars. There are over 100 classes of glycoside hydrolases which have been classified, see e.g. Henrissat et al. (1991) ‘A classification of glycosyl hydrolases based on amino-acid sequence similarities’, J. Biochem. 280: 309-316 and the Uniprot website at www.cazy.org. The glycoside hydrolase family 9 (GH9) consists of over 70 different enzymes that are mostly endoglucanases (EC 3.2.1.4), cellobiohydrolases (EC 3.2.1.91), β-glucosidases (EC 3.2.1.21) and exo-β-glucosaminidase (EC 3.2.1.165).

In recent years, xanthan gum has been used as an ingredient in many consumer products including foods (e.g. as thickening agent in salad dressings and dairy products) and cosmetics (e.g. as stabilizer and thickener in toothpaste and make-up, creams and lotions to prevent ingredients from separating and to provide the right texture of the product). Further xanthan gum has found use in the oil industry as an additive to regulate the viscosity of drilling fluids etc. The widespread use of xanthan gum has led to a desire to degrade solutions, gels or mixtures containing xanthan gum thereby allowing easier removal of the byproducts. Endoglucanases and xanthan lyases for the degradation of xanthan gum and the use of such enzymes for cleaning purposes, such as the removal of xanthan gum containing stains, and in the drilling and oil industries are known in the art, e.g. WO 2013/167581, WO 2018/037064, WO 2018/037065 or WO 2019/162000.

The known endoglucanase having SEQ ID NO:1 and the known xanthan lyase having SEQ ID NO:2 were both found to be sensitive to the presence of detergents, in particular with respect to certain detergent components such as chelators and/or surfactants and/or further enzymes such as proteases. To improve the applicability and/or cost and/or performance of such enzymes, there is an on-going search for variants with altered properties, such as increased stability, e.g. improved stability in a detergent composition as such or improved stability after storage. However, mutagenesis of large enzymes followed by purification and functional analysis of mutant libraries can be very expensive and laborious. Hence, there is ongoing need for stabilized endoglucanase variants and/or xanthan lyase variants for the use in detergent compositions resp. for detergent compositions with improved enzyme stabilization, in particular for detergent compositions in which the enzyme mix containing endoglucanase and/or xanthan lyase shows improved stabilization.

DETAILED DESCRIPTION
Overview of Sequence Listing

SEQ ID NO:1 is the amino acid sequence of the parent mature endoglucanase from a strain of Paenibacillus sp.

SEQ ID NO:2 is the amino acid sequence of the parent mature xanthan lyase from a strain of Paenibacillus sp.

DEFINITIONS

Cleaning or detergent application: the term “cleaning or detergent application” means applying the endoglucanase variant and/or the xanthan lyase variant in any composition for the purpose of cleaning or washing, by hand, machine or automated, on a hard surface or a textile.

Color clarification: During washing and wearing loose or broken fibers can accumulate on the surface of the fabrics. One consequence can be that the colors of the fabric appear less bright or less intense because of the surface contaminations. Removal of the loose or broken fibers from the textile will partly restore the original colors and looks of the textile. By the term “color clarification”, as used herein, is meant the partial restoration of the initial colors of textile.

Corresponding to: The term “corresponding to” as used herein, refers to a way of determining the specific amino acid of a sequence wherein reference is made to a specific amino acid sequence. For example, when references are made to specific amino acid positions, the skilled person would be able to align another amino acid sequence to said amino acid sequence that reference has been made to, in order to determine which specific amino acid may be of interest in said another amino acid sequence. Alignment of another amino acid sequence with e.g. the sequence as set forth in SEQ ID NO:1 or 2 has been described elsewhere herein. Alternative alignment methods may be used and are well-known for the skilled person.

Degrading xanthan gum and xanthan gum degrading activity: The terms “degrading xanthan gum” and “xanthan gum degrading activity” are used interchangeably and are defined as the depolymerization, degradation or breaking down of xanthan gum into smaller components. The degradation of xanthan gum can either be the removal of one or more side chain saccharides, the cutting of the backbone of xanthan gum into smaller components or the removal of one or more side chain saccharides and the cutting of the backbone of xanthan gum into smaller components. A preferred assay for measuring degradation of xanthan gum is the reducing sugar assay as described in examples 2 and 3 herein. Non-limiting examples of the xanthan gum degrading activity include endoglucanase EC 3.2.1.4 activity and/or xanthan lyase EC 4.2.2.12 activity.

Detergent component: the term “detergent component” is defined herein to mean the types of chemicals which can be used in detergent compositions. Examples of detergent components are surfactants, hydrotropes, builders, cobuilders, chelators or chelating agents, bleaching system or bleach components, polymers, fabric hueing agents, fabric conditioners, foam boosters, suds suppressors, dispersants, dye transfer inhibitors, fluorescent whitening agents, perfume, optical brighteners, bactericides, fungicides, soil suspending agents, soil release polymers, anti-redeposition agents, enzyme inhibitors or stabilizers, enzyme activators, antioxidants, and solubilizers. The detergent composition may comprise of one or more of any type of detergent component.

Detergent composition: the term “detergent composition” (or “cleaning composition”) refers to compositions that find use in the removal of undesired compounds from items to be cleaned, such as textiles, dishes, and hard surfaces. The detergent composition may be used to e.g. clean textiles, dishes and hard surfaces for both household cleaning and industrial cleaning. The terms encompass any materials/compounds selected for the particular type of cleaning composition desired and the form of the product (e.g. liquid, gel, powder, granulate, paste, or spray compositions) and includes, but is not limited to, detergent compositions (e.g. liquid and/or solid laundry detergents and fine fabric detergents; hard surface cleaning formulations, such as for glass, wood, ceramic and metal counter tops and windows; carpet cleaners; oven cleaners; fabric fresheners; fabric softeners; and textile and laundry pre-spotters, as well as dish wash detergents). In addition to containing an endoglucanase and/or xanthan lyase, as described herein, the detergent formulation may contain one or more additional enzymes (such as proteases, amylases, lipases, cutinases, cellulases, endoglucanases, xyloglucanases, pectinases, pectin lyases, xanthanases, peroxidases, haloperoxygenases, oxidoreductases, catalases and mannanases, or any mixture thereof), and/or further detergent components.

Dish wash: The term “dish wash” refers to all forms of washing dishes, e.g. by hand or automatic dish wash. Washing dishes includes, but is not limited to, the cleaning of all forms of crockery such as plates, cups, glasses, bowls, all forms of cutlery such as spoons, knives, forks and serving utensils as well as ceramics, plastics, metals, china, glass and acrylics.

Dish washing composition: The term “dish washing composition” refers to all forms of compositions for cleaning hard surfaces. The present disclosure is not restricted to any particular type of dish wash composition or any particular detergent.

Endoglucanase: The term “endoglucanase” or “EG” means an endo-1,4-(1,3;1,4)-β-D-glucan 4-glucanohydrolase (EC 3.2.1.4) that catalyzes endohydrolysis of 1,4-β-D-glycosidic linkages in cellulose, cellulose derivatives (such as carboxymethyl cellulose and hydroxyethyl cellulose), lichenin, β-1,4 bonds in mixed β-1,3 glucans such as cereal β-D-glucans, xyloglucans, xanthans and other plant material containing cellulosic components. A preferred assay for measuring endoglucanase activity is the reducing sugar assay as described in example 2 herein. Non-limiting examples of endoglucanases include the mature parent endoglucanase having SEQ ID NO:1.

Endoglucanase variant having activity on xanthan gum pre-treated with xanthan lyase: The term “endoglucanase variant having activity on xanthan gum pre-treated with xanthan lyase” or an “endoglucanase having activity on xanthan gum pre-treated with xanthan lyase and belonging to the GH9 class of glycosyl hydrolases” is defined as a polypeptide comprising a domain belonging to the GH9 class of glycosyl hydrolases, and having activity (e.g. enzymatic activity, xanthan degrading activity, endoglucanase EC 3.2.1.4 activity) on xanthan gum pre-treated with xanthan lyase. A preferred assay for measuring activity on xanthan gum pre-treated with xanthan lyase is disclosed in example 2 herein.

Enzyme detergency benefit: The term “enzyme detergency benefit” is defined herein as the advantageous effect an enzyme may add to a detergent compared to the same detergent without the enzyme. Important detergency benefits which can be provided by enzymes are stain removal with no or very little visible soils after washing and or cleaning, prevention or reduction of redeposition of soils released in the washing process (an effect that also is termed anti-redeposition), restoring fully or partly the whiteness of textiles, which originally were white but after repeated use and wash have obtained a greyish or yellowish appearance (an effect that also is termed whitening). Textile care benefits, which are not directly related to catalytic stain removal or prevention of redeposition of soils are also important for enzyme detergency benefits. Examples of such textile care benefits are prevention or reduction of dye transfer from one fabric to another fabric or another part of the same fabric (an effect that is also termed dye transfer inhibition or anti-backstaining), removal of protruding or broken fibers from a fabric surface to decrease pilling tendencies or remove already existing pills or fuzz (an effect that also is termed anti-pilling), improvement of the fabric softness, color clarification of the fabric and removal of particulate soils which are trapped in the fibers of the fabric or garment. Enzymatic bleaching is a further enzyme detergency benefit where the catalytic activity generally is used to catalyze the formation of bleaching component such as hydrogen peroxide or other peroxides.

Hard surface cleaning: The term “hard surface cleaning” is defined herein as cleaning of hard surfaces wherein hard surfaces may include floors, tables, walls, roofs etc. as well as surfaces of hard objects such as cars (car wash) and dishes (dish wash).

Improved property: The term “improved property” means a characteristic associated with a variant that is improved compared to the parent. Such improved properties include, but are not limited to, catalytic efficiency, catalytic rate, chemical stability, oxidation stability, pH activity, pH stability, specific activity, stability under storage conditions, chelator stability, substrate binding, substrate cleavage, substrate specificity, substrate stability, surface properties, thermal activity, thermostability, wash performance, or stain removal.

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. The laundering process can be carried out using e.g. a household or an industrial washing machine or can be carried out by hand.

Mature polypeptide: The term “mature polypeptide” means a polypeptide in its final form following translation and any post-translational modifications, such as N-terminal processing, C-terminal truncation, glycosylation, phosphorylation, etc. In one aspect, the mature polypeptide is amino acids 1 to 1055 of SEQ ID NO:1 or amino acids 1 to 1037 of SEQ ID NO:2.

Parent: The term “parent” or “parent endoglucanase” or “parent xanthan lyase” means any polypeptide with endoglucanase resp. xanthan lyase activity to which an alteration is made to produce the enzyme variants. In one aspect, the parent is an endoglucanase (resp. xanthan lyase) having the identical amino acid sequence of the variant, but not having the alterations at one or more of the specified positions. It will be understood that the expression “having identical amino acid sequence” relates to 100% sequence identity. Non-limiting examples of parent endoglucanases include the mature parent endoglucanase having SEQ ID NO:1. Non-limiting examples of parent xanthan lyases include the mature parent xanthan lyase having SEQ ID NO:2.

Sequence identity: The relatedness between two amino acid sequences is described by the parameter “sequence identity”. The sequence identity between two amino acid sequences is 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).

Stability: The term “stability” means resistance or the degree of resistance to change, unfolding, disintegration, denaturation or activity loss. Non-limiting examples of stability include conformational stability, storage stability and stability during use, e.g. during a wash process and reflects the stability of a polypeptide (e.g. an endoglucanase variant or xanthan lyase variant) as a function of time, e.g. how much activity is retained when said polypeptide (e.g. said endoglucanase variant or xanthan lyase variant) is kept in solution, in particular in a detergent solution. The stability is influenced by many factors, e.g. presence of chelators, pH, temperature, detergent composition, e.g. amount of builders, surfactants, chelators etc. The endoglucanase or xanthan lyase stability may be measured as described in examples 2 and 3 herein.

Textile: The term “textile” means any textile material including yarns, yarn intermediates, fibers, non-woven materials, natural materials, synthetic materials, and any other textile material, fabrics made of these materials and products made from fabrics (e.g. garments and other articles). The textile or fabric may be in the form of knits, wovens, denims, non-wovens, felts, yarns, and toweling. The textile may be cellulose based such as natural cellulosic, including cotton, flax/linen, jute, ramie, sisal or coir or manmade cellulosic (e.g. originating from wood pulp) including viscose/rayon, ramie, cellulose acetate fibers (tricell), lyocell or blends thereof. The textile or fabric may also be non-cellulose based such as natural polyamides including wool, camel, cashmere, mohair, rabbit and silk or synthetic polymer such as nylon, aramid, polyester, acrylic, polypropylene and spandex/elastane, or blends thereof as well as blend of cellulose based and non-cellulose based fibers. Examples of blends are blends of cotton and/or rayon/viscose with one or more companion material such as wool, synthetic fibers (e.g. polyamide fibers, acrylic fibers, polyester fibers, polyvinyl alcohol fibers, polyvinyl chloride fibers, polyurethane fibers, polyurea fibers, aramid fibers), and cellulose-containing fibers (e.g. rayon/viscose, ramie, flax/linen, jute, cellulose acetate fibers, lyocell). Fabric may be conventional washable laundry, e.g. stained household laundry. When the term fabric or garment is used it is intended to include the broader term textiles as well.

Variant: The term “variant” means a polypeptide (e.g. an endoglucanase polypeptide or a xanthan lyase polypeptide) comprising an alteration, i.e. a substitution, insertion, and/or deletion, at one or more (e.g. several) positions. A substitution means replacement of the amino acid occupying a position with a different amino acid; a deletion means removal of the amino acid occupying a position; and an insertion means adding one or more (e.g. several) amino acids, e.g. 1-5 amino acids, adjacent to and immediately following the amino acid occupying a position. Non-limiting examples of endoglucanase variants and/or xanthan lyase variants, as described herein, include endoglucanase variants and/or xanthan lyase variants having an activity on xanthan gum (for xanthan lyase) and xanthan gum pre-treated with xanthan lyase (for endoglucanase). Non-limiting examples of variants described herein further include variants having at least 20%, e.g. at least 40%, 50%, 60%, 70%, 80%, 90%, 95%, or 100% endoglucanase activity of the mature parent having SEQ ID NO:1 or SEQ ID NO:2. A preferred assay for measuring activity on xanthan gum (optionally pre-treated with xanthan lyase) is disclosed in examples 2 and 3 herein.

Conventions for designation of variants: The mature polypeptide disclosed in SEQ ID NO:1 is used to determine the corresponding amino acid residue in another endoglucanase and the mature polypeptide disclosed in SEQ ID NO:2 is used to determine the corresponding amino acid residue in another xanthan lyase. The amino acid sequence of another endoglucanase/xanthan lyase is aligned with the mature polypeptide disclosed in SEQ ID NO:1 or, and based on the alignment, the amino acid position number corresponding to any amino acid residue in the mature polypeptide disclosed in SEQ ID NO:1 or 2 is determined using the Needleman-Wunsch algorithm (as described above). Identification of the corresponding amino acid residue in another endoglucanase or xanthan lyase can be determined by an alignment of multiple polypeptide sequences using several computer programs, which are known to the skilled person. In describing the variants, the nomenclature described below is adapted for ease of reference. The accepted IUPAC single letter or three letter amino acid abbreviation is employed.

Substitutions: For an amino acid substitution, the following nomenclature is used: Original amino acid, position, substituted amino acid. Accordingly, the substitution of threonine at position 226 with alanine is designated as “Thr226Ala” or “T226A”. Multiple mutations are separated by addition marks (“+”), e.g. “Gly205Arg+Ser411Phe” or “G205R+S411F”, representing substitutions at positions 205 and 411 of glycine (G) with arginine (R) and serine (S) with phenylalanine (F), respectively.

Deletions: For an amino acid deletion, the following nomenclature is used: Original amino acid, position, *. Accordingly, the deletion of glycine at position 195 is designated as “Gly195*” or “G195*”. Multiple deletions are separated by addition marks (“+”), e.g. “Gly195*+Ser411*” or “G195*+S411*”.

Insertions: For an amino acid insertion, the following nomenclature is used: Original amino acid, position, original amino acid, inserted amino acid. Accordingly, the insertion of lysine after glycine at position 195 is designated “Gly195GlyLys” or “G195GK”. An insertion of multiple amino acids is designated [Original amino acid, position, original amino acid, inserted amino acid #1, inserted amino acid #2; etc.]. For example, the insertion of lysine and alanine after glycine at position 195 is indicated as “Gly195GlyLysAla” or “G195GKA”. An indication of an insertion at a particular position is understood as being an insertion after the original amino acid residue. For example, an “insertion at position 195” is understood to be an insertion after the original residue in position 195.

In such cases the inserted amino acid residue(s) are numbered by the addition of lower-case letters to the position number of the amino acid residue preceding the inserted amino acid residue(s). In the above example, the sequence would thus be:

Parent:
Variant:

195
195 195a 195b

G
G - K - A

Multiple alterations: Variants comprising multiple alterations are separated by addition marks (“+”), e.g. “Arg170Tyr+Gly195Glu” or “R170Y+G195E” representing a substitution of arginine and glycine at positions 170 and 195 with tyrosine and glutamic acid, respectively.

Different alterations: Where different alterations can be introduced at a position, the different alterations are separated by a comma, e.g. “Arg170Tyr,Glu” represents a substitution of arginine at position 170 with tyrosine or glutamic acid. Thus, “Tyr167Gly,Ala+Arg170Gly,Ala” designates the following variants: “Tyr167Gly+Arg170Gly”, “Tyr167Gly+Arg170Ala”, “Tyr167Ala+Arg170Gly”, and “Tyr167Ala+Arg170Ala”. Alternatively, different alterations or may be indicated using brackets, e.g. Arg170[Tyr, Gly] or in one-letter code R170[Y,G].

Wash performance: The term “wash performance” is used as an enzyme's ability to remove stains present on the object to be cleaned during e.g. wash or hard surface cleaning. The improvement in the wash performance may be quantified by calculating the so-called intensity value (Int) in ‘Automatic Mechanical Stress Assay (AMSA) for laundry’ or the remission value (Rem).

Xanthan lyase variant having activity on xanthan gum: The term “xanthan lyase variant having activity on xanthan gum” is defined as a polypeptide that cleaves the β-D-mannosyl-β-D-1,4-glucuronosyl bond of xanthan (e.g. xanthan lyase EC 4.2.2.12 activity). A preferred assay for measuring activity on xanthan gum is disclosed in example 3 herein. Examples of the xanthan lyase variants having activity on xanthan gum, are xanthan lyase polypeptides as such.

The known xanthan endoglucanase having SEQ ID NO:1 and the xanthan lyase having SEQ ID NO:2 are both large enzymes (>1000 amino acid residues). It is therefore extremely laborious and expensive to target its properties for improvement of, e.g. stability in a detergent composition, e.g. in the presence of a surfactant or a chelator.

The inventors have surprisingly found that the stability of specific endoglucanase variants and/or xanthan lyase variants in detergent compositions can be improved by addition of certain enzyme stabilizing components, like e.g. being selected from the group consisting of polyols such as glycerol or 1,2-propylene glycol, alditols such as non-cyclic polyols having the formula HOCH₂[CH(OH)]_nCH₂OH, mannitol, isomalt, lactit, sorbitol, xylitol, threitol, erythritol or arabitol, alkanol amines such as ethanol amine, or formates such as sodium formate, potassium formate, calcium formate or magnesium formate, preferably said enzyme stabilizing component is selected from glycerol and formates, in particular by addition of sodium formate.

In one embodiment, the detergent composition comprises an endoglucanase variant comprising an alteration, preferably a substitution, at one or more positions in one or more regions selected from the group consisting of region 1 corresponding to amino acids 95 to 105 of SEQ ID NO:1, region 2 corresponding to amino acids 115 to 138 of SEQ ID NO:1, region 3 corresponding to amino acids 210 to 251 of SEQ ID NO:1, region 4 corresponding to amino acids 267 to 301 of SEQ ID NO:1, region 5 corresponding to amino acids 339 to 361 of SEQ ID NO:1, region 6 corresponding to amino acids 547 to 595 of SEQ ID NO:1, region 7 corresponding to amino acids 612 to 660 of SEQ ID NO:1, region 8 corresponding to amino acids 806 to 828 of SEQ ID NO:1, region 9 corresponding to amino acids 839 to 1042 of SEQ ID NO:1, region 10 corresponding to amino acids 1 to 94 of SEQ ID NO:1, region 11 corresponding to amino acids 106 to 114 of SEQ ID NO:1, region 12 corresponding to amino acids 139 to 209 of SEQ ID NO:1, region 13 corresponding to amino acids 252 to 266 of SEQ ID NO:1, region 14 corresponding to amino acids 302 to 338 of SEQ ID NO:1, region 15 corresponding to amino acids 362 to 546 of SEQ ID NO:1, region 16 corresponding to amino acids 596 to 611 of SEQ ID NO:1, region 17 corresponding to amino acids 661 to 805 of SEQ ID NO:1, region 18 corresponding to amino acids 829 to 838 of SEQ ID NO:1, and region 19 corresponding to amino acids 1043 to 1055 of SEQ ID NO:1.

In one embodiment, the detergent composition comprises a xanthan lyase variant comprising an alteration, preferably a substitution, at one or more positions in one or more regions selected from the group consisting of region 1 corresponding to amino acids 154 to 176 of SEQ ID NO:2, region 2 corresponding to amino acids 614 to 658 of SEQ ID NO:2, region 3 corresponding to amino acids 731 to 803 of SEQ ID NO:2, region 4 corresponding to amino acids 807 to 846 of SEQ ID NO:2, region 5 corresponding to amino acids 872 to 885 of SEQ ID NO:2, region 6 corresponding to amino acids 903 to 1004 of SEQ ID NO:2, region 7 corresponding to amino acids 1 to 153 of SEQ ID NO:2, region 8 corresponding to amino acids 177 to 613 of SEQ ID NO:2, region 9 corresponding to amino acids 659 to 730 of SEQ ID NO:2, region 10 corresponding to amino acids 804 to 806 of SEQ ID NO:2, region 11 corresponding to amino acids 847 to 871 of SEQ ID NO:2, region 12 corresponding to amino acids 886 to 902 of SEQ ID NO:2, and region 13 corresponding to amino acids 1005 to 1037 of SEQ ID NO:2.

If not explicitly indicated otherwise, all the endoglucanase and/or xanthan lyase variants, as described above, may further comprise one or more additional alterations at one or more (e.g. several) other positions in any of the regions described herein.

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. 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. 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. The identity of essential amino acids can also be inferred from an alignment with a related polypeptide.

In Asia (Japan) a low detergent concentration system is used, while the United States uses a medium detergent concentration system, and Europe uses a high detergent concentration system. A low detergent concentration system includes detergents where less than about 800 ppm of detergent components are present in the wash water. Japanese detergents are typically considered low detergent concentration system as they have approximately 667 ppm of detergent components present in the wash water. A medium detergent concentration includes detergents where between about 800 ppm and about 2000 ppm of detergent components are present in the wash water. North American detergents are generally considered to be medium detergent concentration systems as they have approximately 975 ppm of detergent components present in the wash water. A high detergent concentration system includes detergents where greater than about 2000 ppm of detergent components are present in the wash water. European detergents are generally considered to be high detergent concentration systems as they have approximately 4500 to 5000 ppm of detergent components in the wash water. Latin American detergents are generally high suds phosphate builder detergents and the range of detergents used in Latin America can fall in both the medium and high detergent concentrations as they range from 1500 to 6000 ppm of detergent components in the wash water. Such detergent compositions are all embodiments. A polypeptide may also be incorporated in the detergent formulations disclosed in WO 97/07202.

Hydrotropes

A hydrotrope is a compound that solubilizes 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. Hydrotropes do not display a critical concentration above which self-aggregation occurs as found for surfactants and lipids forming micellar, 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 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 comprise 0 to 5 wt.-%, such as 0.5 to 5 wt.-% or 3 to 5 wt.-%, of a hydrotrope. Any hydrotrope known in the art for use in detergents may be utilized.

In a dish wash detergent, the level of builder is typically 40 to 65 wt.-%, particularly 50 to 65 wt.-%. The builder and/or cobuilder may particularly be a chelating agent that forms water-soluble complexes with Ca²⁺and Mg²⁺. Any builder and/or cobuilder 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), ethanol amines such as 2-amino ethan-1-ol (MEA), diethanolamine (DEA, also known as imino diethanol), triethanolamine (TEA, also known as 2,2′,2″-nitrilo triethanol), and carboxy methyl inulin (CMI), and combinations thereof.

Bleaching Systems

The detergent may comprise 0 to 50 wt.-%, such as 0.1 to 25 wt.-%, of a bleaching system. Any bleaching system known in the art for use in laundry detergents may be utilized. Suitable bleaching system components include bleaching catalysts, photobleaches, bleach activators, sources of hydrogen peroxide such as sodium percarbonate and sodium perborates, preformed peracids and mixtures thereof.

Suitable preformed peracids include, but are not limited to, peroxy carboxylic acids and salts, percarbonic acids and salts, perimidic acids and salts, peroxy monosulfuric acids and salts, e.g. Ox-one®, and mixtures thereof.

The term bleach activator is meant herein as a compound which reacts with peroxygen bleach like hydrogen peroxide to form a peracid. 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 tetra cetyl ethylene diamine (TAED), sodium 4-[(3,5,5-trimethyl hexanoyl)oxy] benzene sulfonate (ISONOBS), diperoxy dodecanoic acid, 4-(dodecanoyl oxy) benzene sulfonate (LOBS), 4-(decanoyl oxy) benzene sulfonate, 4-(decanoyl oxy) benzoate (DOBS), 4-(nonanoyl oxy) benzene sulfonate (NOBS), and/or those disclosed in WO 98/17767. A particular family of bleach activators of interest was disclosed in EP 0624154 and particularly 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 as it eventually degrades into citric acid and alcohol. Furthermore, acetyl triethyl citrate and triacetin has a good hydrolytic stability in the product upon storage and it is an efficient bleach activator. Finally, ATC provides a good building capacity to the laundry additive.

Alternatively, the bleaching system may comprise peroxy acids of, e.g., the amide, imide, or sulfone type. The bleaching system may also comprise peracids such as 6-(phthalo imido) peroxy hexanoic acid (PAP).

Formulation of Detergent Products

The detergent composition may be in any convenient form, e.g. a bar, a homogenous tablet, a tablet having two or more layers, a pouch having one or more compartments, a regular or compact powder, a granule, a paste, a gel, or a regular, compact or concentrated liquid. There are a number of detergent formulation forms such as layers (same or different phases), pouches, as well as forms for machine dosing unit.

Pouches can be configured as single or multicompartment. It can be of any form, shape and material which is suitable for hold the composition, e.g. without allowing the release of the composition from the pouch prior to water contact. The pouch is made from water soluble film which encloses an inner volume. Said inner volume can be divided into compartments of the pouch. Preferred films are polymeric materials preferably polymers which are formed into a film or sheet. Preferred polymers, copolymers or derivates thereof are selected from polyacrylates, water soluble acrylate copolymers, methyl cellulose, carboxy methyl cellulose, sodium dextrin, ethyl cellulose, hydroxy ethyl cellulose, hydroxy propyl methyl cellulose, malto dextrin, polymethacrylates, most preferably polyvinyl alcohol copolymers and, hydroxy propyl methyl cellulose (HPMC). Preferably the level of polymer in the film is at least about 60%. Preferred average molecular weight will typically be about 20000 to about 150000. Films can also be of blend compositions comprising hydrolytically degradable and water-soluble polymer blends such as polylactide and polyvinyl alcohol (known under the Trade reference M8630 as sold by Chris Craft In. Prod. Of Gary, Ind., US) plus plasticizers like glycerol, ethylene glycerol, propylene glycol, sorbitol and mixtures thereof. The pouches can comprise a solid laundry cleaning composition or part components and/or a liquid cleaning composition or part components separated by the water-soluble film. The compartment for liquid components can be different in composition than compartments containing solids (US 2009/011970).

Detergent ingredients can be separated physically from each other by compartments in water dissolvable pouches or in different layers of tablets. Thereby negative storage interaction between components can be avoided. Different dissolution profiles of each of the compartments can also give rise to delayed dissolution of selected components in the wash solution.

A liquid or gel detergent, which is not unit dosed, may be aqueous, typically containing at least 20 wt.-% and up to 95 wt.-%, such as up to 70 wt.-%, 65 wt.-%, 55 wt.-%, 45 wt.-% or 35 wt.-%, water. Other types of liquids, including without limitation, alkanols, amines, diols, ethers and polyols may be included in an aqueous liquid or gel. An aqueous liquid or gel detergent may contain from 0 to 30 wt.-% organic solvent. A liquid or gel detergent may be non-aqueous.

The enzymes may be added to laundry soap bars and used for hand washing laundry, fabrics and/or textiles. The term laundry soap bar includes laundry bars, soap bars, combo bars, syndet bars and detergent bars. The types of bar usually differ in the type of surfactant they contain, and the term laundry soap bar includes those containing soaps from fatty acids and/or synthetic soaps. The laundry soap bar has a physical form which is solid and not a liquid, gel or a powder at room temperature. The term solid is defined as a physical form which does not significantly change over time, i.e. if a solid object (e.g. laundry soap bar) is placed inside a container, the solid object does not change to fill the container it is placed in. The bar is a solid typically in bar form but can be in other solid shapes such as round or oval.

Method of Producing the Composition

Construction, Expression and Purification of Endoglucanase Variants and Xanthan Lyase Variants

Endoglucanase variants, as described herein, and xanthan lyase variants, as described herein, have been constructed and produced as described in WO 2018/037064, WO 2018/037065 and WO 2019/162000 (all three applications are incorporated herein by reference).

Example 2
Detergent Stability Assay for Endoglucanase

GH9 endoglucanase (EG) activity (EC 3.2.1.4) was determined by reducing ends on xanthan gum pre-treated with xanthan lyase using the colorimetric assay developed by Lever (Anal. Biochem. 47: 273-279, 1972). Pre-treated xanthan gum is a modified form of the xanthan sugar, where the terminal pyruvated mannose from side chains is removed (prepared according to Nankai et al. (1999) from the source Keltran). The GH9 mature parent endoglucanase and its variants cleave at beta-(1,4)-glucosyl bonds in the glucan backbone of pretreated xanthan gum releasing glucans with a reducing end which can be determined by reaction with p-Hydroxybenzoic acid hydrazide (PAHBAH). The increase of color is proportional to the enzyme activity. Enzyme sample was mixed with detergent (as exemplified in Table 1) and stored at 30° C. for 8 weeks. After incubation, the enzyme-detergent sample was 100-fold diluted in assay buffer (50 mM MOPS, 4 mM CaCl₂, 0.01% Triton X-100, pH 7.0).

To assess the enzymatic activity, 50 μl of diluted enzyme-detergent sample was mixed with 50 μl 4 mg/ml modified xanthan gum. The samples had then been incubated at 50° C. for 1 hour. Finally, the level of reducing ends is estimated by adding 75 μl PAHBAH solution (15 mg/ml PAHBAH, 50 g/L potassium sodium tartrate tetrahydrate, 20 g/L NaOH), and the samples had then been incubated at 95° C. for 10 minutes. After cooling down to room temperature, the absorbance at 405 nm was measured.

Example 3
Detergent Stability Assay for Xanthan Lyase

Enzyme sample was mixed with detergent (as exemplified in Table 1) and stored at 30° C. for 8 weeks. After incubation, the enzyme-detergent sample was 50-fold diluted in dilution buffer (50 mM MOPS, 1 mM CaCl₂, pH 7.5).

To measure the enzyme activity of diluted enzyme-detergent samples, 50 μl of diluted samples were mixed with 50 μl of freshly prepared substrate solution (0.4% w/v xanthan gum was freshly prepared by dissolving 400 mg of xanthan gum in 100 ml of Milli Q water) and incubated at 40° C. for 1 hour.

After incubation, 75 μl of PAHBAH reagent (1.5% PAHBAH reagent was freshly prepared by dissolving 1.5 g of p-hydroxy benzoic acid hydrazide in a stock solution mix (stock solution mix containing 1.0 M Na₂CO₃, 0.17 M potassium sodium tartrate and 5 mM (Bi(NO3)3 x 5H20) was prepared by dissolving 106.99 g of Na₂CO₃, 47.98 g of potassium sodium tartrate and 2.42 mg of (Bi(NO₃)₃×5H₂O) in Milli Q water for a final volume of 1000 ml)) was added, and the sample was incubated at 90° C. for 10 minutes, followed by subsequent cooling at 10° C. Afterwards, absorbance was measured at 405 nm (Infinite M1000 reader; TECAN, Switzerland).

Example 4
Residual Activity

The in-detergent stability was determined by measuring the enzymatic activity present in detergent fresh, after the enzymes have been added to the detergent and also after storage of the enzymes containing detergent at 30° C.

The residual activity (RA) was calculated as the percentage of enzymatic activity remaining after incubation at 30° C. relative to the enzymatic activity after freshly formulating the enzyme.

S1: Detergent matrix as shown in Table 1 with 0.7 wt.-% (t.q.) of enzyme mix containing endoglucanase and xanthan lyase, as described herein; pH=8

S2: Detergent matrix as shown in Table 1 with additional 5 wt.-% glycerol and 0.7 wt.-% (t.q.) of enzyme mix containing endoglucanase and xanthan lyase; pH =8

S3: Detergent matrix as shown in Table 1 with 1 wt.-% sodium formate and 0.7 wt.-% (t.q.) of enzyme mix containing endoglucanase and xanthan lyase; pH =8

All three samples, S1, S2 and S3, had been stored at 30° C. for 8 weeks. After storage, residual activity of endoglucanase and xanthan lyase had been determined as described above.

From Table 2, it can be seen that endoglucanase as well as xanthan lyase can be stabilized by rather low sodium formate concentrations, whereas elevated glycerol concentration only has a stabilizing effect on xanthan lyase.

Using as low concentration of enzyme stabilizer as possible is especially advantageous in compacted dosage forms, like in particular unit dose, pouches and caps. In this respect, sodium formate shows surprisingly good stabilizing results while being applied in rather low concentration.
