| 摘 要： | 从酒精厂废液、糖厂废糖蜜、土壤及淤泥等七种不同样品中,经富集、分离、纯化,筛选得到两株酒精耐受性较好的酵母菌株TM8和TM23.实验结果表明,两株酵母菌在9%的酒精浓度下,仍然能够保持一定的生长趋势。TM8在渗透压和低酸的耐受性上都要优于TM23.在含150 g/L的葡萄糖的发酵培养基中进行发酵,TM8和TM23所得的酒精终浓度分别为4.0%和3.5%（v/v）.

| Abstract: | Two alcohol-tolerant yeast strains,TM8 and TM23,were isolated from nature.The two strains could grow in culture medium with 9%(v/v) ethanol.The ability of TM8 about osmotic pressure-tolerance and acid-tolerance were more excellent than TM23.Using 150g/L glucose as substrate,the fermented alcohol concentration were 4.0% and 3.5%(v/v) by TM8 and TM23 respectively. |
