Cleaning compositions comprising enzymes
The present invention relates to compositions, methods and use of a mixture of enzymes having DNase activity and an enzyme having hexosaminidase activity.
1. A method for laundering a textile, comprising:
a. exposing a textile to a wash liquor comprising an enzyme having DNase activity and an enzyme having hexosaminidase activity, wherein the enzyme having hexosaminidase activity has at least 80% sequence identity to SEQ ID NO: 19 or at least 85% sequence identity to SEQ ID NO: 20; and
b. completing at least one wash cycle.
2. The method of claim 1 , wherein the enzyme having hexosaminidase activity has at least 85% sequence identity to SEQ ID NO: 19.
3. The method of claim 1 , wherein the enzyme having hexosaminidase activity has at least 90% sequence identity to SEQ ID NO: 19.
4. The method of claim 1 , wherein the enzyme having hexosaminidase activity has at least 90% sequence identity to SEQ ID NO: 20.
5. The method of claim 1 , wherein the enzyme having hexosaminidase activity has at least 95% sequence identity to SEQ ID NO: 19.
6. The method of claim 1 , wherein the enzyme having hexosaminidase activity has at least 95% sequence identity to SEQ ID NO: 20.
7. The method of claim 1 , wherein the enzyme having hexosaminidase activity comprises SEQ ID NO: 19.
8. The method of claim 1 , wherein the enzyme having hexosaminidase activity comprises SEQ ID NO: 20.
9. The method of claim 1 , wherein the enzyme having DNase activity has at least 80% sequence identity to SEQ ID NO: 2.
10. The method of claim 1 , further comprising rinsing the textile.
11. The method of claim 1 , wherein the pH of the wash liquor is in the range 5.5 to 11.
12. The method of claim 1 , wherein the temperature of the wash liquor is from about 20° C. to about 40° C.
13. The method of claim 1 , wherein the textile is pre-treated with an enzyme having DNase activity and an enzyme having hexosaminidase activity.
14. The method of claim 1 , wherein the concentration of DNase in the wash liquor is at least 0.00001 mg/L of enzyme per liter of wash liquor.
15. The method of claim 1 , wherein the concentration of the polypeptide having hexosaminidase activity in the wash liquor is at least 0.00001 mg/L of enzyme per liter of wash liquor.
