Abstract: This study aimed to optimeze the fermentation conditions of Trichoderma reesei for producing cellulase.The results showed that the optimal conditions for producing cellulase are as follows:2‰ wheat brans as carbon source,(NH4)2SO4 as nitrogen source fermentation time 96~120 h,liquid volume in 250 ml flask 60 ml,fermentation temperature 25~30 ℃ and initial pH value 4.5~5.0.

Key words: Trichoderma reesei, cellulase, condition for producing enzyme, fermentation
