| 摘 要： | 为了挑选出适合于甘蔗汁酒精发酵的酵母菌株,优化了两株酵母菌（JL2008和GGFS16）的发酵条件,并研究了优化条件下两株菌以蔗糖及其水解产物（葡萄糖、果糖）为底物时的酒精发酵情况。实验结果表明,两株菌都能很好地将果糖,葡萄糖和蔗糖转化为酒精。相比之下GGFS16的产酒精能力较好,JL2008的耐酸性较强。以150g/L蔗糖作为底物,JL2008和GGFS16发酵酒精浓度分别为8.2%和9.2%（v/v）.

| Abstract: | In order to select a preferable strain for sugarcane juice alcohol fermentation,the factors that affected the alcohol concentration were tested.Under the optimal conditions,sucrose,glucose and fructose were fermented to product alcohol respectively by saccharomyces cerevisiae JL2008 and GGFS16.The results showed that both of the two strains could convert sucrose,glucose and fructose to alcohol efficiently and GGFS16 was more efficient.JL2008 was more acid-resistant than GGFS16.The fermentating alcohol concentration was 8.2% and 9.2%(v/v) by JL2008 and GGFS16 respectively using 150g/L sucrose as a substrate. |
