Abstract
The need for a laundry detergent composition which provides improved removal of stains comprising a combination of mannans and other polysaccharides, is met using a combination of detersive surfactant and a cocktail of enzymes comprising a xanthan endoglucanase, a xanthan lyase, and a mannanase.
Claims20
A laundry detergent composition comprising:
- a) detersive surfactant, wherein the detersive surfactant comprises a combination of anionic and nonionic surfactant;
- b) an enzyme system comprising:
- i. a xanthan endoglucanase, wherein said xanthan endoglucanase comprises a polypeptide with at least about 60% sequence identity to SEQ ID NO:
- 1;
- ii. a xanthan lyase, wherein said xanthan lyase comprises a polypeptide with at least about 60% sequence identity to SEQ ID NO:
- 2, and
- iii. a mannanase, wherein said selected from the group consisting of:
- a) mannanase having mannanase activity and a polypeptide having at least about 85% sequence identity to residues 27-331 of SEQ ID NO:
- 3, SEQ ID NO:
- 3 corresponds to the full-length amino acid sequence of the Man7 mannanase endogenous to Bacillus hemicellulosilyticus including a signal sequence;
- b) mannanase has mannanase activity and a polypeptide having at least about 60% identity to SEQ ID NO:
- 4, the mannanase has mannanase activity and a polypeptide having at least 80% identity to SEQ ID NO:
- 4, wherein SEQ ID NO:
- 4 corresponds to the full-length amino acid sequence of the Man4 mannanase endogenous to Paenibacillus sp;
- c) and mixtures thereof.
