酵母细胞表面工程在生物乙醇生产中的应用

摘要

This paper gives an insight into recent technological progresses in the production of bioethanol using surface engineered yeast, which provides strategies to genetically immobilize amylolytic, cellulolytic and xylanolytic enzymes on yeast cell surface for the production of fuel ethanol from biomass. The expression system of recombinant saccharomyces cerevisiae utilizing starchy and lignocellulosic biomass is highlighted, and its potential of application in bio-ethanol production and also present existing problems are primarily summarized.%介绍了国内外利用酵母表面工程转化各种生物质原料生产生物乙醇的最新技术进展.该技术为在酵母表面基因水平固定淀粉酶、纤维素酶和木聚糖酶从而生产乙醇提供了新的策略.重点阐述了利用淀粉质和木质纤维素原料的重组酿酒酵母表达系统,并对其在生物乙醇生产中的应用潜力以及目前存在的问题做了初步总结.
