摘　　要：木质纤维原料是地球上最丰富的可再生资源,开发木质纤维原料的应用必须经过不同预处理,但预处理过程中均会产生一些副产物,大多数会对后续的糖化及发酵具有抑制作用。针对不同木质纤维素原料采取的预处理方法进行了综合性分析,并阐述了预处理副产物的抑制机理,指出了最有效的抑制物解除方法。最后对如何选择成本低,产生副产物少,且纤维素回收率及酶解率高的预处理方法及其工业生产的应用前景进行了展望。Lignocellulosic materials are the most abtmdant renewable resources on the earth, which need different pretreatment for application. During the pretreatment process, some by-products will be generated, most of which would inhibit the subsequent saccharification and fermentation process. Different pretreatment methods for different lignocellulosic materials were analyzed in this paper. The inhibition mechanisms of the by-products produced in pretreatment were also elaborated; meanwhile the detoxification methods to remove the inhibitors were also exampled. Finally, how to choose the pretreatment method with low cost, less by-products, and high cellulose recovery rate with efficient enzymatic hydrolysis rate were discussed.
