作者创造了一种7小时的粪大肠菌群快速检验法,这是滤膜法的发展。该法使用一种低缓冲乳糖基础培养基和灵敏的 pH 值指示剂。粪大肠菌群在这种培养基上于41.5℃培养7至7.25小时后,在淡紫色的培养基背景上,菌落显黄色,然后对这种典型的菌落进行计数。同时作24小时的滤膜法培养作为对照,将其结果与7小时法的结果相比较。用7小时法计数/24小时法计数的比率来表示二种方法的差别。实验所得的结果是:地面水水样两种方法
The authors created a 7-hour rapid test for fecal coliform bacteria, which is the development of the filter method. This method uses a low-buffered lactose base medium and a sensitive pH indicator. Fecal coliforms colonize on this medium for 7 to 7.25 hours at 41.5 ° C, colonies yellow on a lavender medium background and then count this typical colony. At the same time for 24 hours of membrane culture as a control, the results of the method compared with the results of 7 hours. The difference between the two methods is expressed as the ratio of the 7-hour counting / 24-hour counting. The experimental results are: two kinds of surface water and water methods
