Abstract
Novel cleaning compositions comprising cell wall degrading enzymes are disclosed having pectinases and/or hemicellulases and optionally cellulases. The compositions are particularly suitable for removing stains of vegetable origin, especially from textiles. Although compositions having only one type of such enzymes axe part of the invention (excluding cellulases alone), preferred embodiments have a mixture of cell wall degrading enzyme activities to allow for a concerted action against the fibrous mass which usually constitutes a stain of vegetable origin.
Claims29
A laundry detergent composition comprising at least one plant cell wall degrading substance, wherein said at least one plant cell wall degrading substance comprises at least two plant cell wall degrading enzymes selected from the group consisting of pectinases and hemicellulases, wherein said hemicellulase is a microbial mannanase obtained from strain C11SB.G17 (CBS 480.95).
A method of laundering a soiled fabric comprising the steps of contacting said soiled fabric with a composition comprising a laundry detergent composition comprising at least one plant cell wall degrading substance, wherein said at least one plant cell wall degrading substance comprises at least two plant cell wall degrading enzymes selected from the group consisting of pectinases and hemicellulases, wherein said hemicellulase is a microbial mannanase obtained from strain C11SB.G17 (CBS 480.95).
