木质纤维素新型预处理与顽抗特性
An overview on lignocellulose pretreatment and recalcitrant characteristics
摘要
Abstract
Lignocellulose is the most abundant renewable biomass on the earth. Enzymatic hydrolysis of cellulosic polysaccharide is key step of lignocellulose biorefineries. To enhance efficiency of cellulose hydrolysis, pretreatment is necessary for effectively breaking its recalcitrant structure. So, great attentions have been paid for design of pretreatment technologies to crack recalcitrant characteristics of lignocellulose. In this paper, the latest research progresses on lignocellulose pretreatment and recalcitrant characteristics were reviewed, focusing on the new pretreatment technologies and their main advantages, including combined pretreatment, cold pretreatment, green solvents pretreatment and electrochemical approach. Otherwise, the influence of recalcitrant characteristics, such as lignin, crystallinity, accessibility, on cellulose hydrolysis was discussed. The new methods used for analysis of recalcitrant characteristics and the new insight obtained are highlighted in this review. These are useful for evaluation of pretreatment technologies,and identification of key factors that limit cellulose hydrolysis,and can also be a basis for design and screen of appropriate pretreatment technologies,as well as for understand of lignocellulose hydrolysis mechanism.关键词
