水中致病菌的现有检查法,其缺点是复杂、费力,并需特殊仪器等。据В.М.Фищер的研究,作者用了一种简易方法即凝结培养法,来检查水中的致病菌。操作程序是:取被检水样450毫升(加过氯的水须脱去氯),盛于无菌器内,加入 PH 8.0—8.2的10%蛋白腺水溶液50毫升,于37℃恒温箱中放3小时后,加入10%硫酸铝钾溶液2.5毫升, The existing method of detecting pathogens in water has the disadvantages of being complex, laborious, and requiring special instruments. According to the study of В.М.Фищер, the author used a simple method of coagulation culture to detect pathogens in water. The procedure is: Take the seized water samples 450 ml (plus chlorine water to be dechlorinated), Sheng Sheng in the sterilizer, adding 10% of 8.0-8.2 10% protein gland aqueous solution 50 ml, 37 ° C incubator After 3 hours, 2.5 ml of 10% potassium aluminum sulfate solution was added,
