摘　　要：为了进一步弄清大曲在酒精发酵过程中的作用,以清香型大曲为研究对象,研究了大曲微生物及其内在物质在清香型白酒酵母酒精发酵过程中的作用。结果表明,大曲在清香型白酒酒精发酵过程中不仅提供了具有发酵力作用的酿酒酵母菌株,还提供了能协同促进酿酒酵母完成酒精发酵的菌株;同时,大曲还提供了有助于酵母酒精发酵的物质。In order to further understand the roles of Daqu in ethanol fermentation, in this study, we used Qingxiang Daqu as the research object and investigated the effects of Daqu microbes and its intrinsic materials on ethanol fermentation. The results showed that, Daqu could not only provide S.cerevisiae strains to produce ethanol but also provide some bacterial strains with synergistic reactions with S.cerevisiae to produce ethanol. Besides, Daqu could provide some materials helpful for ethanol fermentation.
