摘　　要：采用多种培养基对衡水老白干酒大曲制曲过程中不同时期的大曲曲坯进行微生物分离。通过对比各种培养基上的微生物种类、菌落数量、形态类别、分离效果等多项指标。结果表明,牛肉膏蛋白胨培养基、MRS培养基、Elliker培养基、马丁氏培养基、麦芽浸出粉培养基分别对老白干香型白酒大曲中的一般性细菌、乳杆菌、乳球菌、霉菌、酵母菌具有较好的分离效果。In this study, multiple culture mediums were used for the isolation of microbes in semi-finished Daqu in different culture period of Hengshui Laobaigan Daqu. Through the comparison of various indexes among different culture mediums such as microbial varieties, colony quantity, morphological type, and isolation effects etc., beef extract-peptone medium, MRS medium, Elliker medium, Martin medium, malt ex- tract powder medium were finally determined as the best isolation mediums for general bacteria, lactobacillaceae, lactococcus, mould and yeast, respectively.
