STUDIES ON THE CELLULASE PRODUCER TRICHODERMA VIRIDE T 99

The cellulase producer Trichoderma viride T 99 was isolated from soil.Under the optimal conditions of culture, the activities of FP, CMCase and β Gase were 120 U,110～125 U,and 90 U,respectively.The components of medium were optimized, and the physical and chemical characters of enzyme were analyzed. The optimal conditions of rice straw enzymolysis were measured.Under the conditions of 50℃,pH4.0,when the substrate concentration was 5% and the time of enzymolysis was 36 h,the conversion rate of substrate and cellulase were 33.49% and 61.33% respectively.
