Determination of the membrane lipid composition of Saccharomyces cerevisiae revealed an increase in the unsaturation index, qualitative and quantitative changes in sterol content and an alteration of the activity of the plasma membrane ATPase when cells were pre-adapted to ethanol. All these changes may constitute different adaptation mechanisms which allow the cell to cope with ethanol stress. The importance of the lipid environment on the plasma membrane ATPase activity is also discussed.
对酿酒酵母细胞膜脂质组成的测定表明，当细胞预先适应乙醇时，不饱和指数增加、固醇含量发生定性和定量变化，以及质膜ATP酶活性改变。所有这些变化可能构成不同的适应机制，使细胞能够应对乙醇胁迫。还讨论了脂质环境对质膜ATP酶活性的重要性。
