【摘要】 高浓度酒精发酵起始于20世纪70年代,主要以可再生资源粮食或植物纤维为原料,采用连续发酵,计算机控制,实现CIP技术,发酵酒精浓度可达12%,酒精得率可达92%～93%,酵母可连续运行200d。经过不断研究,现最终酒精浓度可达16%,淀粉利用率达90%以上,发酵时间50h内。(孙悟)更多还原

【Abstract】 The high concentration fermentation of alcohol started in1970’s.Renewable resources like grains or plant fiber were mainly applied as raw materials.Through consecutive fermentation and under the computer control,CIP techniques implemented and the con-centration of fermented alcohol could achieve12%and the output rate of alcohol achieved92%～93%,the yeast may be continuously use d for200d.Through persistent study,currently,the ultimate concentration of alcohol could achieve16%and the utilization rate of amylum achieved above90%with the fermentation time within50h.(Tran.by YUE Yang)更多还原
