Enzyme hydrolysis result shows that the better substrate is 10% NH3 H2O pretreated corn-cob. And when substrate concentration is 15%(W /V), the optical hydrolysis condition is pH 4. 8, 50 C, enzyme quantity 30U/g substrate.

• 利用所做复合水解酶对预处理玉米芯进行酶水解，当底物浓度为15%25(W/V)，pH值为4.；8，温度为50℃，酶用量30U/g底物时水解效果最好，水解24h后还原糖浓度可达62
