Abstract

The present invention relates to new polypeptides, nucleotides encoding the polypeptide, as well as methods of producing the polypeptides. The present invention also relates to detergent composition comprising polypeptides, a laundering method and the use of polypeptides.

First claim

The invention claimed is:

1. A detergent composition comprising a surfactant and a polypeptide having DNase activity, wherein the polypeptide having DNase activity has at least 90% sequence identity to the polypeptide of SEQ ID NO: 3 or is a fragment thereof having DNase activity.

2. The detergent composition of claim 1 which further comprises at least one additional component selected from:
i. a polyol,
ii. an additional enzyme, and
iii. one or more polymer.

3. The detergent composition of claim 2 , wherein the polyol is selected from glycerol, (mono, di, or tri) propylene glycol, ethylene glycol, polyethylene glycol, sugar alcohols, sorbitol, mannitol, erythritol, dulcitol, inositol, xylitol and adonitol.

4. The detergent composition of claim 2 , comprising at least one additional enzyme, wherein the additional enzyme is selected from the group consisting of proteases, amylases and lipases.

5. The detergent composition according to claim 1 , wherein the surfactant is selected from soap, LAS, AEOS and SLES.

6. The detergent composition of claim 2 , wherein the polymer is selected from (carboxymethyl)cellulose (CMC), poly(vinyl alcohol) (PVA), poly(vinylpyrrolidone) (PVP), poly(ethyleneglycol) and poly(ethylene oxide) (PEG).

7. The detergent composition of claim 1 , wherein the polypeptide having DNase activity has at least 98% sequence identity to the polypeptide of SEQ ID NO: 3.

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

9. A laundering method for laundering an item comprising:
a) exposing an item to a wash liquor comprising the detergent composition of claim 1 ;
b) completing at least one wash cycle; and
c) optionally rinsing the item,

wherein the item is a textile.

10. The method of claim 9 , wherein the pH of the wash liquor is in the range 5.5 to 11.

11. The method of claim 9 , wherein the temperature of the wash liquor is in the range of 5° C. to 95° C.
