Abstract: Considering the physicochemical characteristics and pretreatment necessity of sugarcane bagasse, the recent domestic and abroad research progresses on different pretreatment technologies including physical method, chemical method, biological method and combination method are reviewed systematically. The results and features of various pretreatment technologies are summarized and compared. Finally, the development direction of pretreatment methods in the future is prospected.Sugarcane bagasse is a major solid waste of cane sugar manufacturing process. It has the advantages of high quantity, concentration and abundant fiber content. It could be one of main and potential raw material for the second-generation bioethanol production. The effective pretreatment for lignocellulosic biomass is critical for bioethanol production. It also directly affects enzymatic saccharification and ethanol fermentation of post-processing.

Key words: sugarcane bagasse, cellulose, pretreatment, bioethanol
