    • A gamma-sterilizable nutrient medium based on casein soya peptone agar for the detection of microorganisms in hydrogen peroxide-bearing air or on hydrogen peroxide-bearing surfaces, with a content of between 2 and 10% by weight of sodium thioglycolate, between 5 and 20% by weight of sodium thiosulfate and between 10 and 30% by weight of sodium disulfite in each case with respect to the agar. Preferably the agar used is microbial content test agar and the nutrient medium may contain between 0.1 and 0.25% by weight of sodium pyruvate with respect to the agar. If bromocresol purple and bromocresol violet are used as pH-indicators the nutrient medium may also contain polyvinylpyrrolidone.
    • 基于酪蛋白大豆蛋白胨琼脂的γ消毒营养培养基,用于检测含过氧化氢的空气中或含过氧化氢的表面上的微生物含量为2-10重量%的巯基乙酸钠,为5至20 相对于琼脂,在每种情况下,硫代硫酸钠的重量百分比和10-30%重量的亚硫酸氢钠。 优选地,使用的琼脂是微生物含量测试琼脂,营养培养基可以含有0.1至0.25重量%的丙酮酸钠相对于琼脂。 如果使用溴甲酚紫和溴甲酚紫作为pH指标,营养培养基也可能含有聚乙烯吡咯烷酮。
