丰富的麻疯树废弃物是生产糖和2,3-丁二醇发酵的有前途的可再生原料。为了获得高得率的水溶性产物和高浓度的还原糖，本研究将离子液体（IL）预处理和150℃的稀酸水解相结合。预处理后的生物质的晶体结构被破坏，比表面积增加，使其水解效率提高。与原纤维素相比，经il预处理后还原糖的产率和浓度均提高了139%，水解后水溶性产物的产率提高了128%。与水洗麻疯树皮相比，经il预处理后，还原糖的产率和浓度分别提高了80%和76%，水解后的水溶性产物产率提高了70%。il预处理有利于麻疯树壳水解产物发酵，二醇产率为66.58%，产率由0.35 g/（L·h）提高到0.40 g/（L·h）。
Abundant Jatropha waste is a promising renewable feedstock for the production of sugars and 2,3-butanediol fermentation. To obtain high yield of water-soluble products and high concentration of reducing-sugars, ionic liquid (IL) pretreatment and dilute acid hydrolysis at 150°C were combined in this work. The destruction of crystalline structure and increase surface area of biomasses after IL-pretreatment, made their hydrolysis more efficient. Compared with original cellulose, after IL-pretreatment, both the yield and concentration of reducing-sugars increased by 139%, and the water-soluble products yield increased by 128% after hydrolysis. Compared with water-washed Jatropha hulls, after IL-pretreatment, the yield and concentration of reducing-sugars increased by 80% and 76%, respectively, and the water-soluble products yield increased by 70% after hydrolysis. IL-pretreatment benefited the fermentation of Jatropha hull hydrolysate with 66.58% diol yield and its productivity increased from 0.35 to 0.40 g/(L · h).
