1959年第一季度菌苗污染霉菌的颇多,不仅没加硫柳汞的如此,已加硫柳汞的菌苗也有部分出现了霉菌,由于硫柳汞缺乏,在菌苗内加入1/2万乙酸苯汞,也不能抑制霉菌的生长,因此进行了本试验,以明确各种汞剂的杀霉效能。 1、乙酸苯汞杀霉菌试验: 用不同量的乙酸苯汞,加入已除去霉菌块的污染菌苗中,处理38,52小时,在处理过程中每日摇动数次,然后接种于不滴定PH的琼脂斜面上,大管肉汤及压气肉肝汤中,置室
In the first quarter of 1959, there was a lot of mold and mold contamination. Not only did it not add thimerosal, but some fungal vaccines containing thimerosal also showed mold. Due to the lack of thimerosal, 1/2 million acetic acid phenylmercury was added to the vaccine. The growth of mold was not inhibited, so the test was conducted to clarify the fungicide efficacy of various amalgams. 1. Phenylmercuric-acetic acid and fungicidal test: Add different amounts of phenylmercuric acetate to the contaminated bacterins that have removed the mold and treat it for 38, 52 hours. Shake several times daily during the treatment, then inoculate in the non-titrated PH. Agar slant, large tube broth and contaminated meat liver soup, set the room
