Abstract

With inocula of 6 to 7 log(10) CFU, most vegetative bacteria and spores tested survived on surfaces for more than 5 weeks, but all were inactivated within 90 min of exposure to hydrogen peroxide vapor in a 100-m(3) test room even in the presence of 0.3% bovine serum albumin to simulate biological soiling.

摘要

接种量为6至7 log(10) CFU时，大多数受试的营养细菌和孢子在表面存活超过5周，但即使在存在0.3%牛血清白蛋白以模拟生物污垢的情况下，在100立方米的测试室内暴露于过氧化氢蒸汽90分钟内，所有细菌和孢子均被灭活。
