Screening of A Cellulase-Producing Strain and Optimization on Its Cellulase Production Conditions

A cellulase-producing strain was isolated from the composting sugarcane leaves.And the optimum conditions for cellulase production were determined as follows:culture time of 72 h,culture temperature of 30 ℃,initial pH value of medium of 8,inoculum amount of 3%.Under the optimal conditions,the cellulase activity reached 90.19 U·mL-1.
