[Objective] The effects of ionic liquid 1-ethyl-3-methylimidazolium diethylphosphate ([Emim] DEP) on growth activity of Saccharomyces cerevisiae SY101 were studied by signal factor tests.[Method] Observed the morphological structure and budding of Saccharomyces cerevisiae SY101 at Log growth phase in the presence of different concentration of [Emim] DEP.Drawn growth curve according to numerical value by spectrophotography in liquid suspension culture.[Result] The results indicated that[Emim] DEP could inhibit the growth of yeast.The higher the[Emim] DEP concentration,the more obvious the inhibition effect was.The yeast' s single cell morphology changed when[Emim] DEP concentration was greater than 3 g/L,and its reproduction rate by budding decreased when[Emim] DEP concentration was greater than 10 g/L.The half effective concentration (EC50) of[Emim] DEP to Saccharomyces cerevisiae SY101 were measured by using solid and value were 6.67 g/L.[Conclusion] The study can provide basic data for fuel alcohol residue fermentation.
