摘要
The hydrothermal, ionic liquids-ethanol-water system and the coupling pretreatments were used to separate components of bamboo, the effects of different methods on compositions and enzymatic hydrolysis of bamboo were studied, and the mild hydrogenolysis research of lignin extracted from coupling pretreatment was carried out. The results indicate that hemicellulose is mostly removed after hydrothermal pretreatment, ionic liquids- ethanol- water system can remove large amounts of hemicellulose and lignin. After enzymatic hydrolysis 120 h, glucose yield of bamboo pretreated by hydrothermal, ionic liquids- ethanol- water system and the coupling method are 42.12%, 57.67% and 82.87%, respectively, which are 1.35, 1.85 and 2.66 times of that of untreated bamboo.
