纤维素(植物细胞壁的主要成分)是自然界最丰富的一种可再生资源,但是极难降解利用。纤维素体是一种多酶复合体,能够高效降解纤维素,降解产物能够被某些厌氧微生物利用发酵产乙醇。综述了近年来产纤维素体菌厌氧降解纤维素制乙醇的研究进展,报道了纤维素体结构和功能、重组设计型纤维素体、代谢工程、混菌培养等研究方向的最新成果和思路,并对其前景作了展望。可以预期,随着研究的深入,生物质制乙醇必将日益显示出其强大的市场竞争力。
Cellulose, the main component of plant cell walls, is one of the richest natural resources in the world, but it is extremely difficult to degrade. Cellulose is a multi-enzyme complex, which can degrade cellulose efficiently. Degradation products can be fermented to ethanol by some anaerobic microorganisms. In this paper, the research progress of anaerobic degradation of cellulose made from cellulosic bacteria in ethanol production in recent years was reviewed. The latest achievements and ideas of cellulosic structure and function, recombinant design cellulose, metabolic engineering and mixed culture were reported , And looked forward to its prospects. It is expected that, with the deepening of research, biomass ethanol will inevitably increasingly show its strong market competitiveness.
