ABSTRACT:
The present invention relates to detergent compositions comprising an enzyme preparation with substantial cellulytic activity, especially endoglucanase activity, at alkaline conditions which is enzyme composition is derived from or producible by a fungus selected from the Basidiomycetous families Coprinaceae and Bolbitiaceae, preferably from the group of strains belonging to the genera Psathyrella, Podaxis, Panaeolus, Coprinus and Bolbitius, more preferably from the group of strains belonging to the species Coprinus micaceus, Coprinus domesticus, Coprinus ephemerus, Coprinus disseminatus, Coprinus radians, Coprinus picaceus, Coprinus frisei, Coprinus subimpatiens, Psathyrella candolleana, Psathyrella prona, Panaeolus semiovatus, Podaxis pistillaris and Bolbitius aleuriatus; and a method for providing a stone-washed look to textiles, especially to cellulosic fabric such as denim, using the mentioned enzyme preparation; and a method for improving the drainage of paper pulp or the de-inking of recycled paper using the mentioned enzyme preparation; and an enzyme preparation with substantial cellulytic activity at alkaline conditions which is enzyme composition is derived from or producible by a fungus selected from the Basidiomycetous families Coprinaceae and Bolbitiaceae, provided that the fungus does not belong to the species Coprinus cinereus.
