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 seriously affects the fermentation of hydrolysates.In this paper,we described the types of fermentative inhibitors,the mechanism of their formation and the metabolism of their toxicology,as well as the research advances on techniques for biological detoxification and the biological degradation pathways of different inhibitors.Furthermore,we analyzed its development based on previous researches.
