Escherichia coli ATCC 27622 injured during chlorination of secondary sewage failed to produce colonies on membrane filters incubated on m-FC medium or to grow and produce gas in lactose broth. Thus, standard methods for the enumeration of total and fecal coliforms in water and wastes should not be applied to chlorinated effluents.
在二级污水处理氯化过程中受到损伤的大肠埃希氏菌ATCC 27622,在m-FC培养基上培养的膜滤器上未能形成菌落,在乳糖肉汤中也不能生长并产生气体。因此,用于水和废物中总大肠菌群和粪大肠菌群计数的标准方法不适用于氯化后的废水。
