ABSTRACT:
The subject invention relates to novel compositions of neutral and/or alkaline cellulase and methods for obtaining neutral and/or alkaline cellulase compositions from Chrysosporium cultures, in particular Chrysosporium lucknowense. This invention also provides mutants and methods of generating mutants of Chrysosporium capable of producing neutral and/or alkaline cellulose. This invention also relates to the genes encoding the enzymes comprising the neutral and/or alkaline cellulase composition. In addition, this invention provides methods of culturing Chrysosporium to produce neutral and/or alkaline cellulases. The neutral and/or alkaline cellulase compositions of the subject invention can be used in a variety of processes including stone washing of clothing, detergent processes, deinking and biobleaching of paper & pulp and treatment of waste streams.
