The Optimal Fermentation Conditions of Cold-active Cellulase Strain CNY086(Ⅱ) / 微生物学通报

ABSTRACT

Based on the research of text (Ⅰ) which determined the fermentation medium, the fermentation condition of CNY086 including temperature, volume, inoculum and inoculum age had been studied by single factor and orthogonal experiment. The optimum temperature, liquid volume, inoculum and seed age were 15?C, 250 mL/500 mL, 15%, 10 h. Under the conditions above mentioned, enzyme activity reached 104.36 U/mL in 5 L fermentor.
