摘要： 在木质纤维素类生物质结构中,木质素是生物质中纤维素与半纤维素进行生物降解的天然抗性屏障,预处理是打破木质纤维素抗性结构这一阻碍生物转化与利用瓶颈的最主要途径。本文分别概述了木质纤维素蒸汽爆破预处理技术与生物预处理技术的研究现状,介绍了蒸汽爆破-生物联合预处理的研究进展,分析了蒸汽爆破预处理过程中抑制物产生的机理和主要抑制物的种类,并提出了具有脱毒效果的蒸汽爆破-生物联合预处理技术,以及木质纤维素高效预处理技术研究发展方向。

Abstract: In the structure of lignocellulosic biomass,lignin is the natural resistant barrier in the biological degradation of cellulose and hemicellulose. The most critical step to break the barrier,which is the bottleneck of biological conversion and utilization,is pretreatment. The recent research progresses of steam explosion pretreatment technology and biological pretreatment technology of lignocellulose are summarized in this article,and the recent research progress of steam explosion-biological combination pretreatment is introduced. This paper also analyses main types of inhibitors and their mechanisms of products during steam explosion pretreatment. A new pretreatment with the detoxification function, steam explosion-biological combination pretreatment,as well as the development direction of the research of efficient pretreatment technology for lignocellulose, is proposed.

Key words: steam explosion, biological pretreatment, detoxification
