Abstract

A modified cellulase and method of preparing is disclosed which comprises a cellulase composition which is treated with a protease wherein at least one proteolytically stable cellulase is present in the cellulase composition. The disclosed cellulase composition may be used in the treatment of lignocellulosic material, the treatment of animal feed, the treatment of waste water, the treatment of textiles, stonewashing or in laundry detergents.
