离子液体[Bmim]Cl对酿酒酵母AY92022生长的影响

考察了不同浓度的离子液体对酿酒酵母AY92022（Saccharomyces cerevisiae AY92022）生长的影响，以在不合氯化1-丁基，3甲基咪唑的土豆培养基中生长的酿酒酵母AY92022为对照组。结果发现，当Bmim]Cl的浓度低于10^-6g／L时，酵母菌生长受到的影响较小。随着离子液体浓度的增大，酵母菌生长受到的影响逐步增大，当Bmkn]Cl的浓度为10-^-3g／L时，其稳定生长期的菌体浓度为0．0101g／mL，为对照组的63．5％；葡萄糖浓度为1．59％时，为对照组的2．41倍；乙醇浓度为4．83g／L时，为对照组的61．4％。

Influence on the Growth of Saccharomyces Cerevisiae AY92022 by [Bmim]Cl

Compared with the growth of Saccharomyces cerevisiae AY92022 in suspended YPD medium without EBmim]Cl, the influence of different concentrations of ionic liquids on the growth of AY92022 was studied. The results showed that when concentration of Bmim]Cl was 10-6 g/L, the growth of the yeast was almost the same with the control group. With the increase of the concentration of Bmim]Cl, the growth of AY92022 was affacted gradually, and when the concentration of Bmim] CI was 10^-3 g/L, the concentration of biomass in stationary phase was 0. 010 1 g/mL, which was 63.5% of the concentration in the control group, the glucose content increased to 1.59% ,which was 2.41 times in the control group, and the concentration of ethanol in was 4. 83 g/L,which was 61.4% of the concentration in the control group.
