纤维质酒精预处理液中抑制剂脱毒方法研究进展

摘要

利用纤维质原料生产燃料酒精是目前研究的热点。综述了纤维质原料预处理液中抑制物脱毒方法的研究进展。介绍了抑制物形成、抑制机理、抑制物对微生物生长和酒精发酵的影响以及脱毒方法的进展情况。指出选择适宜的预处理及脱毒方法、尤其选育耐抑制物的菌株是实现纤维质原料生产燃料酒精工业化研究的重点。%The research on fuel ethanol from lignocellulosic material is a hot topic.Research progress of detoxification methods in inhibitors in lignocellulosic material-pretreated hydrolysate was reviewed.Formation of fermentation inhibitors,mechanism of inhibitors,the effect of inhibitors on microbial growth and ethanol fermentation and development of detoxification methods were introduced.Appropriate pretreatment and detoxification methods and the selection of tolerant-inhibitor strains are the focus of further research.
