Nutrient medium for detecting microbes in presence of hydrogen peroxide, useful for checking efficiency of fumigation, contains sulfur-containing salts for neutralizing peroxide

摘要

A nutrient medium (A) that can be sterilized by gamma-rays, and is based on casein-soya peptone agar, contains (by weight of the agar) 2-10% sodium thioglycolate; 5-20% sodium thiosulfate and 10-30% sodium disulfite. It is used to detect microorganisms in hydrogen peroxide (HP)-containing air or on HP-containing surfaces.
