Two media were developed that allowed both a total coliform count and an Escherichia coli count to be determined on the same medium after 24 h of incubation at 35 degrees C. The new media were tested along with two standard media on 10 surface water and 7 sewage samples. The experimental media yielded equivalent or higher counts relative to the standard media and recovered more specifically the desired indicator groups as determined by colony identification.
开发了两种培养基,在35摄氏度下培养24小时后,可在同一培养基上同时测定总大肠菌群数和大肠杆菌数。将这两种新培养基与两种标准培养基一起在10份地表水和7份污水样本上进行测试。通过菌落鉴定确定,实验培养基相对于标准培养基产生了相当或更高的菌落数,并且更特异性地回收了所需的指示菌群。
