Coliforms, primarily Citrobacter freundii, gave negative verification results in the total-coliform membrane filtration test. The organisms produced gas from lactose in brilliant green bile broth but not in lauryl tryptose broth. The discrepancy was related to the peptone sources used in the media.
大肠菌群,主要是弗氏柠檬酸杆菌,在总大肠菌群膜过滤试验中验证结果为阴性。这些微生物在亮绿胆盐肉汤中能利用乳糖产气,但在月桂基胰蛋白胨肉汤中则不能。这种差异与培养基中使用的蛋白胨来源有关。
