         10 . The detergent composition according to  claim 1  further comprising a builder. 
     
     
         11 . The detergent composition according to  claim 1 , wherein said composition is in a solid form. 
     
     
         12 . The detergent composition according to  claim 1 , wherein said composition is in a liquid form. 
     
     
         13 . The detergent composition according to  claim 4 , wherein said detergent composition comprises a solvent. 
     
     
         14 . The detergent composition according to  claim 1 , wherein said polypeptide having deoxyribonuclease activity is selected from the group consisting of a polypeptide having at least 85% sequence identity to the mature polypeptide of SEQ ID NO: 1, a polypeptide having at least 85% sequence identity to the amino acid sequence set forth in SEQ ID NO: 2, a polypeptide having at least 85% sequence identity to the amino acid sequence set forth in SEQ ID NO: 3, a polypeptide having at least 85% sequence identity to the mature polypeptide of SEQ ID NO: 4, a polypeptide having at least 85% sequence identity to the mature polypeptide of SEQ ID NO: 5 and a polypeptide having at least 85% sequence identity to the mature polypeptide of SEQ ID NO: 6. 
     
     
         15 . The detergent composition according to  claim 1 , wherein said polypeptide having deoxyribonuclease activity is selected from the group consisting of a polypeptide comprising or consisting of the mature polypeptide of SEQ ID NO: 1, a polypeptide comprising or consisting of the amino acid sequence set forth in SEQ ID NO: 2, a polypeptide comprising or consisting of the amino acid sequence set forth in SEQ ID NO: 3, a polypeptide comprising or consisting of the mature polypeptide of SEQ ID NO: 4, a polypeptide comprising or consisting of the mature polypeptide of SEQ ID NO: 5 and a polypeptide comprising or consisting of the mature polypeptide of SEQ ID NO: 6.
