Abstract: For making use of defatted soybean meal,the influence factor during the cellulase produced by trichoderma koningiisolidity fermentation and cellulase enzyme hydrolysisof defatted soybean meal. The major affecting factors of solidityfermentation are temperature , pH , medium moisture content and time.The major affecting factors of enzymatic hydrolysis arepH value, temperature and time .It showed that the adequate condition for enzyme production is temperature (30℃), pH (4.5),medium moisture content 2.5:1, time (4d), and cellulase activity produced is 7.98U/g. And we also proceeded enzyme hydrolysisby cellulase produced, the optimum condition is temperature 50℃, pH 5.0, time3d, the yield of enzyme hydrolysis is 5.32%.

Key words: defatted soybean meal, trichoderma koningii, solidity fermentation, enzymatic hydrolysis
