一、过去情况:据资料介绍:“5406”抗生菌生长温度为16-45℃,最适为28-30℃,母剂在28-30℃条件下保温5-7天即可出产品。二、试验过程: 第一点:(45-16)×0.618+16=33.9≈34℃。第二点:取原定最适温度28℃为一点。第三点:(45+28)-34=39℃。按以上三种温度分别进行保温培养,四天后34℃的即出产品(灰白色的孢子长至瓶底)。28℃与39℃的孢子生长均较差些,经含菌量测定:34℃的为33.04亿/克;28℃为
First, the past situation: According to the information: “5406” antibacterial growth temperature of 16-45 ℃, the most suitable for 28-30 ℃, 28-30 ℃ parent material in the insulation 5-7 days to the product. Second, the test process: The first point: (45-16) × 0.618 +16 = 33.9 ≈ 34 ℃. The second point: take the original optimum temperature of 28 ℃ for a little. The third point: (45 + 28) -34 = 39 ℃. According to the above three kinds of temperature were incubated, respectively, four days after the product is 34 ℃ (gray spores grow to the bottom of the bottle). 28 ℃ and 39 ℃ spores were poor, the determination of the amount of bacteria: 34 ℃ to 3.304 billion / g; 28 ℃ is
