훈증소독제, Fumagari OPP®의 Escherichia coli와 Salmonella typhimurium에 대한 살균효과

Bactericidal Efficacy of Fumagari OPP®, Fumigant Against Escherichia coli and Salmonella typhimurium

초록

본 연구는 E. coli와 S. typhimurium을 대상으로 orthophenylphenol 20%를 함유한 훈증소독제, Fumagari OPP$^{(R)}$의 살균효과를 평가하기 위해 수행되었다. 예비 시험에서, E. coli와 S. typhimurium의 현탁액 균수는 모두 $4.0{\times}10^8CFU/mL$이었으며, 모든 훈증소독제에 노출시킨 담체의 균수는 모두 평판배지법과 여과법으로 배양한 시험균주 현탁액의 균수의 50%보다 많았다. 또한, 대조 담체로부터 회복된 E. coli와 S. typhimurium 균수는 모두 $3.4{\times}10^6CFU/mL$이었다. 훈증소독제의 살균효과 시험에서는, 훈증소독제를 처리한 담체의 E. coli와 S. typhimurium의 감소 균수는 각각 5.64와 5.26 logCFU/mL로 나타났다. 이상의 결과로부터, 훈증소독제, Fumagari OPP$^{(R)}$은 E. coli와 S. typhimurium에 대해 효과적인 살균력을 갖는 것으로 확인되었으며, 병원성 세균에 오염된 식품재료 및 주방용품의 소독에 적용할 수 있을 것으로 사료된다.

Abstract

This test was performed to evaluate the bactericidal efficacy of Fumagari OPP$^{(R)}$, fumigation disinfectant, containing 20% ortho-phenylphenol against Escherichia coli (E. coli) and Salmonella typhimurium (S. typhimurium). In preliminary tests, both E. coli and S. typhimurium working culture suspension number (N value) was $4.0{\times}10^8$ CFU/mL. And all of the colony numbers on the carriers exposed the fumigant (n1, n2, n3) were higher than 0.5N1 (the number of bacterial test suspentions by pour plate method), 0.5N2 (the number of bacterial test suspentions by filter membrane method) and 0.5N1, respectively. In addition, the mean number of bacteria recovered on the control-carriers (T value) was $3.4{\times}10^6$ CFU/mL. In the bactericidal effect of the fumigant, the reduction number of S. typhimurium and E. coli (d value) was 5.26 and 5.64 logCFU/mL, respectively. According to the French standard for the fumigant, the d value for the effective bactericidal fumigant should be over than 5 logCFU/mL. With the results of this study, Fumagari OPP$^{(R)}$ has an effective bactericidal activity, then the fumigant can be applied to disinfect food materials and kitchen appliances contaminated with pathogenic bacteria.
