ABSTRACT
21 cold-active strains which produced cold-active cellulase were isolated from Bohai Bay. One of the strains CNY01 was a kind of Trichoderma viride and its cellulase activity was 67.30 U/mL. Through UV and DES mutation, the strain CNY086 was bred and its cellulase activity was 92.17 U/mL. The strain CNY086 had stable ability to produce cellulase. Through orthogonal experiment, the optimal condition of the fermentation medium had been tested. The suitable medium was that straw power 1.20%, bran 0.70%, (NH4)2SO4 0.50%, KH2PO4 0.55%, in this condition the cellulase activity came to 108.55 U/mL.
