Claims20
A method of treating a fabric, comprising contacting the fabric with an aqueous solution of a hexosaminidase having β1,6 N-acetylglucosaminidase activity, wherein the fabric comprises a biofilm comprising polymers of N-acetyl-glucosamine (PNAG), wherein
- (a) the amino acid sequence of the hexosaminidase has at least 90% sequence identity to the amino acid sequence of SEQ ID NO:
- 3, and
- (b) the biofilm is reduced or removed from the fabric.
A method for cleaning or laundering a fabric, comprising
- (a) exposing the fabric to a wash liquor comprising a detergent composition comprising a hexosaminidase having β1,6 N-acetylglucosaminidase activity, wherein the amino acid sequence of the hexosaminidase has at least 90% sequence identity to the amino acid sequence of SEQ ID NO:
- 3, and wherein the fabric comprises a biofilm comprising polymers of N-acetyl-glucosamine (PNAG);
- and
- (b) completing at least one wash cycle;
- wherein the biofilm is reduced or removed from the fabric.
