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.
Cette invention concerne une protéine de cellulase modifiée qu'on utilise avec profit dans le traitement de textiles. Il s'agit plus particulièrement d'un procédé de traitement d'un tissu contenant de la cellulose qui consiste à former une solution aqueuse contenant une composition de cellulase qui diffère d'une cellulase précurseur en ce qu'elle a été agrandie; et à mettre en contact la solution aqueuse avec un tissu contenant de la cellulose pendant une durée et dans des conditions appropriées pour traiter le tissu. La cellulase agrandie peut comprendre une composition multimère d'au moins deux unités distinctes de cellulase ou une cellulase unique à laquelle ont adhéré des constituants polymères ou fibreux.
