小麦淀粉生产酒精中酵母菌所需的营养

Investigation on the Nutrition in Need for Microzyme during Alcohol Production by Wheat Starch

对用小麦淀粉生产酒精过程酵母菌所需营养进行分析。结果表明,以发酵促进剂作为发酵营养补充剂,可有效提高酵母活力,促进酵母繁殖和代谢产酒精的能力;酒母罐细胞数提高20%～35%,出芽率提高15%～20%,发酵周期缩短8～10 h,淀粉出酒率可达54%以上。

The nutrition in need for microzyme during alcohol production by wheat starch was investigated.The results showed that the use of fermentation promoter as nutritional supplement could effectively promote microzyme activity and advance microzyme reproduction and metabolism and strengthen its alcohol-producing capability.Its use could increase cells number in yeast tank by 20 %～35 %,increase sprouting rate by 15 %～20 %,shorten fermenting period by 8～10 h,and increase alcohol yield up to above 54 %.
