The Enzymatic Hydrolysis and Dilute Sulfuric Acid Hydrolysis of Corn Stalk Compared

This paper describes the experiment of hydrolysis of cellulose under enzyme and acid hydrolyzing, the hydrolysis properties of Suhong cellish L and Cellusoft L compared with dilute sulfuric acid from the main affecting factor of hydrolysis (time, temperature, substrate concentration etc.) and mechanism. The results show that the different mechanism of enzyme and acid hydrolysis result in diverse influence on hydrolyzing corn stalk. The velocity of enzymatic hydrolysis was slower than that of acid hydrolysis, while the yield was much higher. The yield of hydrolyzing corn stalk would be higher if combining enzyme and acid hydrolyzing.
