Abstract
The present invention relates to a modified cellulase protein which is advantageously used in the treatment of textiles. Particularly, a method for treating a cellulose containing fabric is provided comprising the steps of forming an aqueous solution comprising a cellulase composition which differs from a precursor cellulase in that it has been enlarged and contacting the aqueous solution with a cellulose containing fabric for a time and under conditions appropriate to treat the fabric. The enlarged cellulase may comprise a multimeric composition of two or more distinct cellulase units or a single cellulase which has had adhered thereto polymeric or fibrous constituents.
