Abstract
The present invention relates to detergent compositions comprising one or more enzymes which are immobilized by a covalent binding on an activated polymer. Such enzymes are preferably bound to the activated polymer via a spacer molecule. The enzymes are selected from a variety of enzymes including, for example, cellulases, hemicellulases, peroxidases, proteases, glucoamylases, amylases, lipases, cutinases, pectinases, reductases, oxidases, phenoloxidases, lipoxygenases, laccases, ligninases, pullulanases, xylanases, tannases, pentosanases, manlanases, .beta.-glucanases, arabinosidases, and mixtures thereof. The polymer is selected from a variety of polymers. A preferred polymer for use in the present invention is polyethylene glycol.
