不同温度刺激处理白云边酒大曲细菌研究

研究采用不同温度、不同激活时间激活培养大曲中的微生物,对中温曲和高温曲中的细菌、酵母菌、霉菌和放线菌采用稀释涂平板法进行分离培养。结果表明,不同的温度和热激条件对大曲微生物的培养存在差异;大曲中细菌数量最多,酵母次之,霉菌量少,放线菌基本没有发现;快生型细菌不管是在中温曲还是在高温曲中都普遍存在,数量最多的是中温曲,对白云边酒的风格特征的形成有一定的作用。

Study on the Bacteria in Baiyunbian Daqu Activated at Different Temperature

Microbes in culture Daqu was activated at different temperature and in different activation time.Then bacteria,microzyme,mould,and actinomycetes in medium-temperature Daqu and in high-temperature Daqu were isolated by dilute plate method.The results showed that different temperature and different thermal stimulus would result in great difference in microbes culture in Daqu.In Daqu,the quantity of bacteria was the maximum,then microzyme,then mould,and there was rare actinomycetes.Fast-growing bacteria was ub...
