摘要:

以MS2噬菌体为指示微生物, 检验了7种不同成分的消毒剂 (双氧水、乙醇、发酵乳酸消毒剂、络合碘消毒剂、复合季铵盐消毒剂、含氯消毒剂和过氧乙酸消毒剂) 对噬菌体的杀灭效果. 结果表明, 被广泛使用的消毒剂对病毒杀灭的效果差异较大. 络合碘消毒剂具有最强的杀灭作用, 其次为复合季铵盐消毒剂和过氧乙酸消毒剂, 而双氧水、乙醇和发酵乳酸消毒剂的杀灭效果较差. 该试验结果可为合理配置消杀环境中有害微生物的消毒剂提供参考依据.

关键词: 消毒剂, MS2噬菌体, 杀灭率, 灭活对数值

Abstract:

In this study, the MS2 phages were used as an indicator microorganism to test the function of seven disinfectants with different components: hydrogen peroxide, ethanol, fermented lactic acid disinfectant, iodine disinfectant, quaternary ammonium disinfectant, chlorine-containing disinfectant, and peracetic acid disinfectant. Our results showed that the virus disinfection rate varied notably between the selected disinfectants. The iodine disinfectant exhibited the strongest disinfection effect, followed by the quaternary ammonium salt disinfectant and the peracetic acid disinfectant, while the disinfection effects of hydrogen peroxide, ethanol, and fermentation lactic acid disinfectant were inadequate. The test results provide a reference for the efficient utilization of various disinfectants to eliminate harmful microorganisms in the environment.

Key words: disinfectant, MS2 phage, disinfection rates, disinfection logarithm values
