Method for producing cellulase and method for producing glucose using it

摘要

PROBLEM TO BE SOLVED: To provide a cellulase having a high biomass-degrading activity for hydrolyzing biomass into glucose by improving a method for culturing a Trichoderma filamentous fungus having a cellulase-producing ability. SOLUTION: The method for producing cellulase includes culturing Trichoderma filamentous fungus and causing the Trichoderma filamentous fungus to produce cellulase, and a lactose-containing ammonia water in which lactose is dissolved at 250 g / L or more is subjected to Trichoderma genus. Includes addition to the culture during the culture of Trichoderma. [Selection diagram] None
