Abstract

This invention relates to novel detergent compositions comprising bacterial mannanase enzymes. The detergent compositions comprising bacterial mannanases are useful in laundry and cleaning applications wherein degradation or modification of mannan is desired. The invention also relates to the use of said detergent compositions in laundry and cleaning applications as well as a method for degrading mannan.

Claims (11)

1. A detergent composition comprising at least one enzyme having an amino acid sequence having at least 96% sequence identity to the amino acid sequence of SEQ ID NO: 12, wherein the at least one enzyme has mannan degrading activity.

2. The detergent composition of claim 1 , wherein the at least one enzyme has an amino acid sequence having at least 98% sequence identity to the amino acid sequence of SEQ ID NO: 12.

3. The detergent composition of claim 1 , wherein the at least one enzyme has an amino acid sequence having at least 99% sequence identity to the amino acid sequence of SEQ ID NO: 12.

4. The detergent composition of claim 1, 2, or 3 , wherein the composition further comprises one or more additional enzymes selected from the group consisting of: protease, lipase, cutinase, amylase, carbohydrase, cellulase, pectinase, pectatlyase, mannanase, arabinase, galactanase, xylanase, oxidase, xanthanase, laccase, and/or peroxidase enzymes.

5. The detergent composition of claim 1 , wherein the composition is in form of 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.

6. The detergent composition of claim 1 , wherein the detergent composition is a laundry detergent composition, preferably a liquid or solid laundry detergent composition.

7. A method for degrading mannan, the method comprising administering the detergent composition of any one of claim 1, 2, or 3 .

8. The method of claim 7 , wherein the method is part of a laundry process.

9. A method for removing a stain from a surface, comprising contacting the surface with a detergent composition according to claim 1, 2, or 3 .

10. A method for degrading mannan comprising applying a detergent composition according to claim 1 to mannan.

11. The method for degrading mannan of claim 10 , wherein the mannan is on the surface of a textile.
