Abstract

Total thermotolerant coliforms (TTC) and Escherichia coli strains were isolated from sewage from a treatment plant before and after peracetic acid (PAA) disinfection. The plasmid profiles of 120 E. coli strains were analyzed. Although PAA disinfection effectively reduced the number of TTC and E. coli strains, the percentage of E. coli strains containing plasmids was not statistically different among water samples. The sizes of the plasmids found ranged from < 3 kb to > 56 kb, but plasmids of between 3 and 5 kb were encountered most frequently.

摘要

从一家污水处理厂经过和未经过过氧乙酸（PAA）消毒处理的污水中分离出了总耐热大肠菌群（TTC）和大肠杆菌菌株。对120株大肠杆菌菌株的质粒图谱进行了分析。虽然PAA消毒有效地减少了TTC和大肠杆菌菌株的数量，但水样中含有质粒的大肠杆菌菌株百分比在统计学上并无差异。所发现的质粒大小范围从小于3 kb到大于56 kb，但最常遇到的是3至5 kb之间的质粒。
