In this study, the substitute of culture mediums of yeast strains was explored. The fermentation contrast experiment was performed at 38 ℃ of yeast strains cultured by corn mash, corn filtrate, and traditional wort respectively. The results suggested that there was significant difference in alcohol content fermented by yeast strains cultured by mediums of different concentration. For example,while the ratio of corn and water was 1∶2, alcohol content of fermenting broth by yeast strains cultured by corn mash...
