Abstract:In China the biomass that could be used to produce ethanol in large quantity is lignocellulose.The main challenges of ethanol production from lignocellulosic materials are the saccharification process by which lignocellulosics is transformed into sugar.The methods of enhancing hydrolysis efficiency of cellulase are as follows:(1) the lignocellulose is pretreated,(2) the optimal condition of cellulase hydrolysis is studied,(3) cellulase recycle is conducted,4) the reasonable fermentation process is adopted,and so on.The structures of cellulose and hydrolysis way of cellulase are analyzed.The progress in research of a few pretreatment methods and the effect of different pretreatment methods on hydrolysis efficiency are mainly reviewed,the optimal condition of cellulase hydrolysis,cellulase recycle use,and the reasonable fermentation process are analyzed.
Keywords:cellulase  lignocellulose  hydrolysis efficiency  ethanol
