Abstract

The present invention relates to compositions such as cleaning compositions comprising a mix of enzymes. The invention further relates, use of compositions comprising such enzymes in cleaning processes.

First claim

What is claimed is:

1. A cleaning composition comprising
(a) a DNAse having at least 85% sequence identity to the polypeptide of SEQ ID NO: 13,
(b) a mannanase having mannanase activity and at least 90% sequence identity to the polypeptide of SEQ ID NO: 82, and
(c) a cleaning component.

2. The cleaning composition of claim 1 , wherein the DNase has at least 90% sequence identity to the polypeptide of SEQ ID NO: 13.

3. The cleaning composition of claim 1 , wherein the DNase has at least 95% sequence identity to the polypeptide of SEQ ID NO: 13.

4. The cleaning composition of claim 1 , wherein the DNase has at least 98% sequence identity to the polypeptide of SEQ ID NO: 13.

5. The cleaning composition of claim 1 , wherein the DNase is the polypeptide of SEQ ID NO: 13.

6. The cleaning composition of claim 1 , wherein the mannanase has at least 95% sequence identity to the polypeptide of SEQ ID NO: 82.

7. The cleaning composition of claim 1 , wherein the mannanase has at least 97% sequence identity to the polypeptide of SEQ ID NO: 82.

8. The cleaning composition of claim 1 , further comprising a cellulase.

9. The cleaning composition of claim 8 , wherein the cellulase is selected from the group consisting of:
a polypeptide having at least 80% sequence identity to the polypeptide shown in SEQ ID NO: 83,
a polypeptide having at least 80% sequence identity to the polypeptide shown in SEQ ID NO: 84,
a polypeptide having at least 80% sequence identity to the polypeptide shown in SEQ ID NO: 85, and
a polypeptide having at least 80% sequence identity to the polypeptide shown in SEQ ID NO: 86.

10. The cleaning composition of claim 1 , further comprising an amylase.

11. The cleaning composition of claim 10 , wherein the amylase is a polypeptide selected from the group consisting of:
a polypeptide having at least 80% sequence identity to the polypeptide shown in SEQ ID NO: 88,
a polypeptide having at least 80% sequence identity to the polypeptide shown in SEQ ID NO: 89,
a polypeptide having at least 80% sequence identity to the polypeptide shown in SEQ ID NO: 90, and
a polypeptide having at least 80% sequence identity to the polypeptide shown in SEQ ID NO: 91.

12. The cleaning composition of claim 1 , further comprising a xylanase.

13. The cleaning composition of claim 12 , wherein the xylanase is a polypeptide having at least 80% sequence identity to the polypeptide shown in SEQ ID NO: 87.

14. The cleaning composition of claim 1 , wherein the DNase comprises one or both of the motif(s) [D/M/L][S/T]GYSR[D/N] (SEQ ID NO: 73) or ASXNRSKG (SEQ ID NO: 74).

15. The cleaning composition of claim 1 , wherein the amount of the DNase is from 0.01 to 1000 ppm and the amount of the mannanase is from 0.01 to 1000 ppm.

16. The cleaning composition of claim 1 , wherein the cleaning component is a surfactant.

17. The cleaning composition of claim 16 , wherein the surfactant is an anionic and/or nonionic surfactant.

18. The cleaning composition of claim 1 , wherein the cleaning component is a builder or bleach component.

19. A kit for deep cleaning, which comprises a solution of a mixture comprising (a) a DNase having DNA activity and at least 85% sequence identity to the polypeptide of SEQ ID NO:13, (b) a mannanase having mannanase activity and at least 90% sequence identity to the polypeptide of SEQ ID NO: 82, and (c) a cleaning component.

20. A method of deep cleaning a textile, comprising washing the textile with a cleaning composition of claim 1 .
