Abstract

The present invention relates to cleaning compositions, including laundry, dishwashing, household cleaning and oral/dental compositions, comprising a xylan degrading alkaline enzyme and a non-plant cell walls degrading enzyme.

Description

CLEANING COMPOSITIONS COMPRISING XYLAN DEGRADING ALKALINE
'- ENZYME AND NON-PLANT CELL WALLS DEGRADING ENZYME

Field of the Invention The present invention relates to cleaning compositions, including laundry, dishwashing, household cleaning and oral/dental compositions, comprising a xylan degrading alkaline enzyme and a non-plant cell walls degrading enzyme.
Background of the invention Performance of a cleaning product, for use in washing or cleaning method, is judged by a number of factors, including the ability to remove soils, and the ability to prevent the redeposition of the soils, or the breakdown products of the soils on the articles in the wash.
Removal by detergents of stains stemming from plants, wood, mould-clay based soil and fruits is on of the thoughest cleaning challenge.
Especially in the laundry processes wherein the tendency is to move to low wash temperatures and shorter washing cycles. These stains typically contain complex mixtures of fibrous material, based mainly on carbohydrates -and their derivatives, fibre and cell wall components.
- 35 Moreover, such stains are generally accompanied by amylose, sugars and their derivatives. Specific examples of such soils would include orange, tomato, banana, tea, mango, broccoli, spinash soils and grass.
In particular, food soils are often difficult to remove effectively from a soiled item. Highly coloured or 'dried-on' soils derived from fruit and/or vegetables are particularly challenging soils to remove. Indeed processed or cooked vegetables and fruits often contain non-plant cell walls materials used for the processing, cooking and flavouring of the food : butter, milk, eggs, oils such as soya or olive oil, thickeners, sweeteners such as sugar.
These material are often based on proteins, fats and/or starches.
The items can be fabrics, hard surfaces and dishware such as plasticware, glassware or chinaware, or teeth and mouth.
It is therefore an object of the present invention to provide a cleaning composition which significantly improves the removal of a broad range of plant based stains. It is another object of the present invention to provide a cleaning composition which enhances fabric realistic items cleaning and whitening.
The above objective has been met by formulating cleaning 2o compositions comprising a xyian degrading alkaline enzyme and a non-plant cell walls degrading enzyme, especially a protease, lipase and/or amylase.
In a preferred embodiment, the present invention relates to a laundry and/or fabric care composition comprising a xylan degrading alkaline enzyme and a non-plant cell walls degrading enzyme, especially a protease, lipase and/or amylase, which enhances fabric realistic items cleaning and whitening. In a second embodiment, the present invention relates to dishwashing or household cleaning compositions comprising a xylan degrading alkaline enzyme and a non-plant cell walls degrading enzyme, especially a protease, lipase and/or amylase and in a third embodiment, the present invention relates to oral/dental care compositions comprising a xylan degrading alkaline enzyme and a non-plant cell walls degrading enzyme, especially a protease, lipase and/or amylase.
Xylan degrading enzymes like xylanase are commonly used in the paper/pulp industry and to a lesser extent also in the starch/baking industry.
In WO 94/01532 is disclosed a method for producing enzymes from strains of the alkalophilic species Bacillus sp. AC 13. Enzymes obtainable from these strains are proteases, xylanases and cellulases as well. The protease and cellulase enzymes are demonstrated to be valuable for use in detergents while on the other hand xylanase is shown to be of use in processes for treatment of lignocellulosic pulp i.e. the paper pulp industry.
In WO 92/06209 is disclosed that xylanase enzymes are overexpressed by microbial strains constructed via genetic techniques free 0 of cellulolytic enzymes. These xylanase enzymes are described for use in a variety of applications like the bleaching of wood pulps and the modification of cereals and grains for use in baking and the production of animal feeds.
In WO 92/19726 are disclosed stabilised, modified enzymes. The ~ 5 naturatty occurring amino acids (other than proline) have been substituted with a proline residue at one or more positions. Among the modified enzymes, amylases, lipases, cellulases, xylanases and peroxidases are mentioned. Said stabilised, modified enzymes can be used in detergent compositions.
EP 709 452 recognises the benefits for use of xylanase at low levels in cleaning formulations.
WO 95/35362 describes cleaning compositions containing plant cell walls degrading enzymes such as pectinases and/or hemicellulases and/or optionally cellulases. The cleaning properties of the xylanases enzymes were tested in non-enzymes containing detergents.
As can be seen from the above, cleaning benefits of the combined 3o use of xylan degrading alkaline enzymes with non-plant cell walls degrading enzymes, especially protease, lipase and/or amylase, have not been previously recognised.
Summar~r of the invention The present invention relates to cleaning compositions comprising a xylan degrading alkaline enzyme and a non-plant cell walls degrading WO 98/39403 PCTIiJS97/03557 enzyme, especially a protease, lipase and/or amylase, which significantly improve the removal of a broad range of plant based stains.
Detailed description of the invention The xvlan de4rading alkaline enzyme An essential component of the cleaning compositions of the invention is a xylan degrading alkaline enzyme. The cleaning compositions of the present invention significantly improve the removal of a broad range of plant based stains. In addition, it has been found that the cleaning compositions ~ 5 of the present invention enhance fabric realistic items cleaning and whitening.
Without wishing to be bound by theory, it is believed that the xylan degrading alkaline enzyme is capable of attacking specific parts of plant/fruit 2o cell constituents, breaking them down and facilitating removal during the wash process. This goes by random endo-hydrolysis of the xylan component or by successive exo-hydrolysis of xylose residues from the non-reducing end of the xylan polymer chain or by removal of substituents such as acetyl, 4-O-methyl glucuronic side chains, the L-arabinose side chains 25 and ferulic acid cross linkages and p-coumaric side chains from the xylan polymer of the plant/fruit cells. Moreover, the xylan degrading activity enhances the accessibility of other detergent ingredients such as non-plant cell walls degrading enzymes, at the stain/soil.
3o By xylan degrading enzyme it is meant herein any enzyme which degrade, for instance hydrolyse and/or modify, xylan containing polymers which are associated with hemicellulose and other plant polysaccharides.
By xylan degrading alkaline enzyme it is meant a xylan degrading enzyme having -an enzymatic activity of at least 10%, preferably at least 35 25%, more preferably at least 40% of its maximum activity at a pH ranging from 7 to 12. Preferably, a xylan degrading enzyme having its maximum activity at a pH ranging from 7 to 12.

The xylan degrading alkaline enzyme can be a single xyian degrading activity species or a mixture of the iso-enzymes obtained via the purification ._ of the crude xylan degrading alkaline enzyme mixure. The xylan degrading 5 enzymes of interest are the endo- and exo-Xylanases hydrolysing Xyian in endo- or in exo fashion: endo-1,3 beta Xylosidase (E.C. 3.2.1.32) , the endo-1,4-beta Xylanase (E.C. 3.2.1.8), 1,3-beta D Xylans Xyiohydrolase,(E.C. 3.2.1.72), 1,4 -beta D Xylans Xylohydrolase,lE.C.
3.2.1.371. Other Xylan degrading alkaline enzymes of interest remove ~o substitutions from the main xylan polymer such as Acetylxylan esterase ;
Glucuronoarabinoxyian endo-1,4-xyianase (E.C. 3.2.1.136), arabinosidase (E.C.3.2.1.55) and ferulic esterase and coumaric acid esterase. These enzymes remove respectively the acetylation , 4-O-methyl glucuronic side chains ; the L-arabinose side chains and ferulic acid cross linkages and p-~ 5 coumaric side chains from the main xylan polymer.
The xylan degrading alkaline enzymes can be produced as the wild types by alkalophilic micro-organisms, but also the genes encoding the xylan degrading alkaline enzymes can be cloned and expressed in suitable 2o hosts. The cloned xylan degrading alkaline enzymes are either the natural wild types or the protein engineered enzymes for improved compatibility with detergents. Examples of micro-organisms suitable for the production of the enzymes are listed : Bacillus species: AC13(NCIMB 40482); SD 902 (FERM P-13356); BX-1; BX-2; BX-3; BX-4 ; DSM 71 197; W2 (FERM P-25 7221 ); W4 (FERM P-7223); C-%(-2 (FERM P-1698); TAR-1; V1-4; 41 M 1;
K-12; B. stearothermophilus; B. polymyxa; B. circulans; Thermotoaa s ecies: T. neopolitama; T. thermarium.; Stre~tomvces species:
S.viridosporus (ATCC 391 15) S. olivochromogenes; As~eraillus species: A.
phoenicis; Humicola species: H. insolens; Trichoderma species: T. reesei 30 (VTT-D-86271-RUT C30); Actinomadura flexuosa; Microtetetraspora flexuosa ; Thermonaspora fusca KW 3 (DSM 6013); E.coli and variants carrying plasmid pCX31 1; Cepholosporum (NCL 87.1 1.9); Actinomycetes.
- Nowadays, it is common practice to modify wild-type enzymes via protein / genetic engineering techniques in order to optimise their - 35 performance efficiency in the cleaning compositions of the invention. For example, the variants may be designed such that the compatibility of the enzyme to commonly encountered ingredients of such compositions is increased. Alternatively, the variant may be designed such that the optimal pH, bleach stability, catalytic activity and the like, of the enzyme variant is tailored to suit the particular cleaning application.
In particular, attention should be focused on amino acids sensitive to oxidation in the case of bleach stability and on surface charges for the surfactant compatibility. The isoelectric point of such enzymes may be modified by the substitution of some charged amino acids, e.g. an increase in isoelectric point may help to improve compatibility with anionic surfactants. The stability of the enzymes may be further enhanced by the creation of e.g. additional salt bridges and enforcing calcium binding sites to increase chelant stability.
Pulpzyme HB and Pulpzyme HC from Novo Nordisk and xylanase ~ 5 L120000 from Solvay are commercial available xylan degrading alkaline enzymes.
Said xylan degrading alkaline enzyme is incorporated into the compositions of the present invention preferably at a level of from 20 0.0001 % to 2%, more preferably from 0.0005% to 0.5%, most preferred from 0.001 % to 0.05% pure enzyme by weight of the composition.
The non-plant cell walls de4rading enzyme The cleaning compositions further comprise one or more non-plant cell walls degrading enzymes which provide cleaning performance and/or fabric care benefits.
3o By non-plant cell wall degrading enzymes, it is meant to exclude the three broad enzyme classes of cellulases, hemicellulases and pectinases (Ward and Young (1989), CRC Critical Rev. in Biotech. 8, 237-2741.
Celluiolytic enzymes have been traditionally divided into three classes endoglucanases, exoglucanases or cellobiohydrolases and (3-glucosidases (Knowles, J. et al. (1987) TIBTECH 5, 255-2611. Examples of pectinases are pectin esterase, pectin lyase, pectate lyase and endo- or exo-polygalacturonase (Pilnik and Voragen (1990) Food Biotech 4, 319-328), enzymes degrading hairy regions such as rhamnogalacturonase and accessory enzymes ISchols et al. (1990), Carbohydrate Res. 206, 105-115;
Searle Van Leeuw et al. ( 1992) Appl. Microbiol. Biotech. 38, 347-349).
Galactanase, arabinase, lichenase and mannase are some hemicellulose degrading enzymes.
Non-plant cell walls degrading enzymes include enzymes selected from the group of protein degrading enzymes such as proteases, Keratanase, from the group of starch-and starch-derivatives degrading enzymes like: alfa-,beta- and iso-amylases, pullulanase, from the group of polysaccharide degrading enzymes such as isomaltase, glucoamylase, dextranase, mycodextranase, invertase, lactase, insuiinase and from the group of oligosaccharide degrading enzymes such as lysozym, endoglycosidaseH, alfa- and beta-N-acetylgalactosaminidases, ~ 5 neuraminidase, chondroitinase, hesperinidase, hyaluronidase and chitinase.
Also suitable are enzymes selected from the group of esters and fat's and wax-hydrolysing enzymes like lipase, phospholipases, esterases and cutinases and enzymes of the group of oxidoreductases such as peroxidases, laccases. Preferred are those enzymes being of the alkaline 20 type.

Suitable lipases include those which show a positive immunological cross-reaction with the antibody of the lipase, produced by the microorganism Pseudomonas fluorescent IAM
1057. This lipase is available from Amano Pharmaceutical Co. Ltd., Nagoya, 3o Japan, under the trade name Lipase P "Amano," hereinafter referred to as "Amano-P". Other suitable commercial lipases include Amano-CES, lipases ex Chromobacter viscosum, e.g. Chromobacter viscosum var. lipolyticum - NRRLB 3673 from Toyo Jozo Co., Tagata, Japan; Chromobacter viscosum lipases from U.S. Biochemical Corp., U.S.A. and Disoynth Co., The 35 Netherlands, and lipases ex Pseudomonas gladioli. Especially suitable lipases are lipases such as M 1 LipaseR and LipomaxR (Gist-Brocades) and LipolaseR
