| 摘 要： | 从四川阿坝地区采收的威代尔冰葡萄果实中分离出葡萄酒酵母，通过产气能力和产醇能力实验，初筛出4株产气和产醇能力强的酵母菌，并通过WL培养基鉴别，4株酵母菌均为酿酒酵母。将4株酿酒酵母与对照葡萄酒酵母进行耐受性能比较，分离得到的V9酵母菌对温度、酸度、糖度、酒精度及SO2均有较好的耐受性，具有地区特色葡萄酒的发酵潜能。

| Abstract: | The yeasts in Vidal ice grapes fxom Aba area, Sichuan were isolated and purified. Four yeasts were filtered by the capacity of gas production and alcohol production test. And the four yeasts were all Saccharomyces cerevisiae which were identification by WL medium. The tolerance properties of these strains were compared with wine yeasts. The V9 yeast had excellent tolerance properties against temperature, acidity, alcohol, sugar, and sulfur dioxide, with potential to produce unique regional ice wine of Aba area in Sichuan. |
