| 摘 要： | 以存活率为指标,探讨了不同时期不同面包酵母的耐盐性能、耐酒精性能、耐高温性能以及耐冷冻性能,并且测定了不同时期菌体胞内海藻糖含量,研究结果表明胞内海藻糖含量与酵母的耐受性之间存在一定的相关性,海藻糖含量越高,酵母的耐性越好。

| Abstract: | The freeze-tolerance,the stress resistance and the trehalose content of different baker yeasts in the different periods was discussed.It was found that there was a correlation between the trehalose content and the stress resistance,and there was a better stress resistance with the higher trehalose content. |
| |
| Keywords: | baker yeast trehalose stress resistance freeze-tolerance survival rate |
