摘　　要：白酒生产常用的发酵容器有泥壁窖和石壁窖,通过对这两种窖池不同层面酒醅中微生物的研究,结果表明:泥壁窖和石壁窖出窖酒醅的微生物区系在数量及类别上存在一定差异。同一层面,好氧菌和霉菌数量是石壁窖略多于泥壁窖;兼性厌氧菌数量则是泥壁窖明显多于石壁窖,尤其是下层更突出;酵母菌数量在两种窖间的差异不明显;两种窖酒醅微生物均以兼性厌氧菌为主,霉菌极少,酵母更少甚至检测不出。Liquor production usually use mud wall pit and stone wall pit as the fermented container. Based on the research on fermented grains microbes of different spaces to two materials of pits, the results showed that fermented grains microbe quantity and category has certain difference in mud wall pit and stone wall pit. In the same space, the amount of aerobic bacteria and mould in stone wall pit is slightly more than mud wall pit; facultative anaerobe amount is mud wall pit significantly more than stone wall pit, especially the lower space even more prominent; yeast amount between two kinds of pits is no obvious difference; two kinds of pits fermen- ted grains microbes were predominantly facultative anaerobic bacteria, a small am- ount of mould, even less yeast.
