摘　　要：木质纤维素组分结构复杂,未处理的木质纤维素很难直接被微生物和酶降解。解决了木质素的降解问题,就能在很大程度上提高木质纤维素的降解性能,因此研究开发有效的预处理技术是一种合理利用木质纤维素的重要方法。经过预处理使木质纤维素首先降解成结构简单的组分,有利于进一步发酵生产乙醇或甲醇。预处理木质纤维素是提高原料利用率,缩短生产时间的有效手段。Due to the special structure,untreated lignocellulosic was not able to be degraded directly by microbial and enzyme.In order to improve the lignocellulosic degradation rate,the lignin degradation issue should be solved in the first place.One of the most important methods of degrading lignin was to develop an appropriate pre-treatment of lignocellulosic,after pretreatment of lignocellulosic,which broke lignin into simple elements before fermenting to produce ethanol or methanol.Pretreatment of lignocellulosic materials was to increase raw material utilization,effective means of reducing production time.
