摘　　要：目的研究环氧乙烷与二氧化碳混合气体杀菌效果。方法采用载体定量杀菌试验和模拟现场消毒试验方法,对环氧乙烷混合气体杀菌效果进行了实验室和模拟现场试验观察。结果在常温常湿条件下,用50 g/m3环氧乙烷混合气体熏蒸24 h,或用100 g/m3的该混合气体熏蒸5 h,对1 m3密闭玻璃柜内菌片上大肠杆菌和金黄色葡萄球菌杀灭率可达90%以上;对菌片上枯草杆菌黑色变种芽孢杀灭率仅达73%以上。在相同条件下,对集装箱模拟现场消毒效果与上述结果类似。结论环氧乙烷混合气体对集装箱内细菌繁殖体杀灭效果较好,但对细菌芽孢杀灭效果较差,需要改变消毒条件。Objective To study the germicidal efficacy of ethylene oxide and carbon dioxide mixed gas. Methods The carrier quantitative method and simulated scenes trial were used to observe germicidal efficacy of the ethylene oxide mixed gas in laboratory and simulated scenes. Results On the condition of normal temperature and humidity, the killing rates of Escherichia coli and Staphylococcus aureus on carrier in 1 m3 airtight glass - box exposed to the mixed gas 50 g/m3 for 24 hours or the mixed gas 100 g/m3 for 5 hours were above 90% ; while the killing rate ofBacillus subtilis var. niger spores on carrier was only above 73%. With the same condition, the germicidal efficacy of simulated scenes trail in container was similar. Conclusion The germicidal efficacy of ethylene oxide mixed gas on the vegetative form of bacteria is better, but that on bacterial spores is not so good. So the disinfection condition should be changed.
