摘要
纤维素酶应用于发酵酒精工业可提高燃料酒精和白酒的出酒率、原料的利用率、缩短发酵时间。对纤维质原料制酒精的研究主要有酿酒酵母的合理运用和性能改良、发酵过程优化、提高利用率,降低成本等。克隆或原生质体融合技术可改良发酵菌株的纤维素酶基因,构建工程发酵酵母,提高纤维素的利用率,对产酒精具有广阔的发展前景。
The utilization of cellulase in alcohol fermentation industry could evidently increase liquor yield and fuel alcohol yield, enhance the use rate of raw materials, and shorten fermentation time,The research on alcohol production by cellulose mainly covered the following aspects： proper use and property transformation of S.cerevisiae, the optimization of fermentation process, and the approaches to reduce production cost and to increase utilization rate etc. The techniques inlcuding clone and protoplast fusion could improve cellulase genes of fermented strains, construct engineering S.cerevisiae, and increase the use rate of cellulase, which had a promising prospect in alcohol production.
