OPTIMIZATION OF SOLID FERMENTATION CONDITION FOR CELLULASE PRODUCTION BY TRICHODERMA KONINGII

The solid fermentation condition for cellulose production by Trichoderma koningii was optimized.The activities of FPA,CMCase were assayed.The results showed: the ideal prescription for cellulase complex production by Trichoderma koningii and the solid fermentation condition were that using straw powder/wheat bran(3∶2) as carbon source,300% water,1% NH4SO2,0.1% Tween-80,cultured 4 days at 28 ℃.The initial pH could affect the CMC activity greatly,the highest enzyme activity occurred at pH 3.0,but the initial pH affected the FPA activity slightly,the highest activity occurred at pH 5.0.
