| Abstract: | The culture conditions for the production of cellulases was optimized by using Trichoderma.koningii N 18.Results indicated that the highest level of Solid fermentation occurred in the optimal ration of straw and bran 6：2,and ammonium sulfate was the best nitrogen source with the optimal ratio of C：N 6：1.And the water content was 200% with the optimal conditions of enzyme pH 6.0.The optimal culture temperature was 28 ℃,and the optimal time was 7d.Under the optimal culture condition,the activities of CMcase and FPAase were 321.64U·mL^-1 and 59.58 U·mL^-1,respectively. |
