摘　　要：设置单因素试验考察不同浓度离子液体氯化1-丁基-3-甲基咪唑([BMIM]Cl)对酿酒酵母(Saccharomyces cerevisiae)AS2.399生长及其乙醛脱氢酶活性的影响。结果表明,[BMIM]Cl对酵母的生长有抑制作用,且其浓度越高,抑制作用越明显;低浓度的[BMIM]Cl可以提高酵母乙醛脱氢酶的活性,高浓度则会抑制其活性。The effects of ionic liquid 1-butyl-3-methylimidazolium chlorine（[BMIM]C1） on growth and aldehye dehydrogenase （ALDH） activity of Saccharomyces cerevisiae AS2.399 were studied by signal factor tests. The results indicated that [BMIM^C1 could inhibit the growth of yeast. The higher the [BMIM]C1 concentration, the more obvious the inhibition effect was. The activity of ALDH could be promoted by low concentration of [BMIM]C1 while inhibited by high concentration.
