摘　　要：以自选的5株酵母菌为出发菌种进行酒精发酵试验,最终获得1株适宜以甜高梁汁液为原料进行液体发酵的高产酵母菌株,其最佳发酵条件为:温度32℃,pH值5.5,接种量0.6mL,糖度19Brix。In this paper,five sorts of yeast strains were studied by liquid-state fermentation. Finally a kind of yeast with high alcohol yield was screened,which was suitable for the production of liquid-state fermentation. The optimum alcohol fermentation process conditions were：the temperature of 32 ℃,the pH of 5.6,the yeast consumption of 0.6 mL,the concentration of sweet sorghum stalk juice of 19 Brix.
