Abstract

Cleaning compositions having an enzyme system, where the enzyme system includes a nuclease enzyme, an extracellular-polymer-degrading enzyme, and a cleaning adjunct. Methods of making and using such cleaning compositions. Use of an extracellular-polymer-degrading enzyme.

First claim

What is claimed is:

1. A cleaning composition comprising an enzyme system,
the enzyme system comprising:
(a) a nuclease enzyme;
(b) an extracellular-polymer-degrading enzyme that is a mannanase with greater than about 90% identity to SEQ. ID NO. 10 ( Chaetomium virescens ); and
(c) a cleaning adjunct.

2. A cleaning composition according to claim 1 , wherein the nuclease enzyme is a deoxyribonuclease enzyme, a ribonuclease enzyme, or a mixture thereof.

3. A cleaning composition according to claim 1 , wherein the nuclease enzyme is selected from any of E.C. classes E.C. 3.1.21.x (where x=1, 2, 3, 4, 5, 6, 7, 8, 9), 3.1.22.y (where y=1, 2, 4, 5), E.C. 3.1.30.z (where z=1, 2) or E.C. 3.1.31.1, or mixtures thereof.

4. A cleaning composition according to claim 1 wherein the nuclease enzyme comprises a deoxyribonuclease enzyme.

5. A cleaning composition according to claim 1 in which the nuclease enzyme comprises a nuclease enzyme having both RNase and DNase activity.

6. A cleaning composition according to claim 1 , wherein the nuclease enzyme is a microbial enzyme.

7. A cleaning composition according to claim 1 , wherein the nuclease enzyme has an amino acid sequence having at least 85%, or at least 90 or at least 95% or even 100% identity with the amino acid sequence shown in SEQ ID NO:1, SEQ ID NO:2 or SEQ ID NO:3.

8. A cleaning composition according to claim 1 , wherein the enzyme system comprises a mannanase having greater than about 95% identity to SEQ. ID NO. 10 ( Chaetomium virescens ).

9. A cleaning composition according to claim 8 , wherein the mannanase has greater than about 98% identity to SEQ. ID NO. 10 ( Chaetomium virescens ).

10. A cleaning composition according to claim 1 , wherein the enzyme system comprises additional enzymes selected from a protease, an amylase, a lipase, or combinations thereof.

11. A cleaning composition according to claim 1 , wherein the cleaning adjunct comprises from about 1% to about 80%, by weight of the cleaning composition, of a surfactant system.

12. A cleaning composition according to claim 10 , wherein the surfactant system comprises an anionic surfactant.

13. A method of cleaning a surface, a textile, comprising mixing the cleaning composition according to claim 1 with water to form an aqueous liquor and contacting a textile with the aqueous liquor in a laundering step.

14. A cleaning composition according to claim 3 , wherein the nuclease enzyme is selected from E.C. class E.C. 3.1.21.x (where x=1, 2, 3, 4, 5, 6, 7, 8, 9).

15. A cleaning composition according to claim 14 , wherein the nuclease enzyme is selected from E.C. class E.C. 3.1.21.1.

16. A cleaning composition according to claim 5 , wherein the nuclease enzyme having both RNase and DNase activity is from E.C. 3.1.30.2.

17. A cleaning composition according to claim 6 , wherein the nuclease enzyme is a bacterial enzyme.

18. A cleaning composition according to claim 9 , wherein the mannanase has greater than about 99% identity to SEQ. ID NO. 10 ( Chaetomium virescens ).

19. A cleaning composition according to claim 12 , wherein the anionic surfactant comprises a member selected from the group consisting of alkyl sulfate, alkyl alkoxy sulfate, alkyl benzene sulfonate, paraffin sulfonate, and mixtures thereof.

20. A cleaning composition according to claim 19 , wherein the anionic surfactant comprises a member selected from the group consisting of alkyl sulfate, alkyl alkoxy sulfate, alkyl benzene sulfonate, and mixtures thereof.
