【摘要】 大肠菌群是指能发酵乳糖、产酸产气、需氧和兼性厌氧的革兰氏阴性无芽孢杆菌。啤酒生产过程中可能会污染大肠菌群。因此,国家规定发酵酒必须检测大肠菌群。为杜绝啤酒产品在生产流通过程中污染大肠菌群,可采用菌落计数法直观、简易地检测啤酒中的大肠菌群,效果良好。(孙悟)更多还原

【Abstract】 Coliform group referred to aerobic or facultative anaerobic gram-negative budless bacillus which could ferment lactose and produce acids and CO2. However, contamination of coliform group might occur during beer brewing. Accordingly, the government had formulated the provision that coliform group of fermented wine must be determined in the production to avoid the contamination of coliform group. And group-counting method, simple to operate, was applied to determine coliform group and better effects were achieved.(Tran. by YUE Yang)更多还原
