摘　　要：稀酸是木质纤维素水解生成可发酵性糖的重要催化剂,但会伴随产生大量的微生物代谢抑制物,严重影响水解物的可发酵性。文中介绍了发酵抑制物的种类、形成机理、代谢毒理,以及不同抑制物的生物降解途径与生物脱毒方法的研究进展,在此基础上对其发展方向作了进一步分析。Dilute acid is an important catalyst for generating fermentable sugar through lignocellulose hydrolysis. But this process will be accompanied by production of a large number of microbial metabolic inhibitors, which serious-ly affects the fermentation of hydrolysates. In this paper, we described the types of fermentative inhibitors, the mecha-nism of their formation and the metabolism of their toxicology, as well as the research advances on techniques for bio-logical detoxification and the biological degradation pathways of different inhibitors. Furthermore, we analyzed its de-velopment based on previous researches.
