Abstract
Optimization studies on cellulase production from corn stover by Arachniotus sp. under continuous shaking conditions showed that addition of (NH4)2S04'MgS04.7H20, cscr, 2HP and KHZP04 to the fermentation medium enhanced cellulose production. Maximum endoglucanase (1.15IU/ml/min), exoglucanase (O.64IU/ml/min) and 13-glucosidase(1.12IU/mVmin) activity was recorded after 24 hours continuous shaking fermentation (120rpm) in the culture medium of 7.5% corn stover containing (NH4)zS04'0.2%; CaClz.2Hp, 0.05%;MgS04.7Hp, 0.01% and KHZP04, 0.2% at pH 4 and 32QC. Key words: Arachniotus sp., cellulase optimization, continuous shaking fermentation
