笔者对配制肉汤琼脂培养基的方法进行了改进,改进后的制法为:取胨、氯化钠加入肉汤液内,微温溶解后,调节pH为7.4～7.6,再加入琼,脂,加热、煮沸。待琼脂完全溶化后,混匀,过滤,分装,15磅20min灭菌。改进后的配制方法较原法操作更为方便,且pH值也更易调节准确。用改进后的制法配制的培养基接种培养金黄色葡萄球菌、大肠杆菌、绿脓杆菌生长均良好。用于药品的卫生检验,结果
The method of preparing broth agar was improved. The improved method is as follows: peptone and sodium chloride are added into the broth solution, and after being slightly warmed, the pH value is adjusted to 7.4-7.6, Heat and boil. After agar is completely dissolved, mix, filter, aliquot and sterilize at 15 lbs. The improved preparation method is more convenient than the original method and the pH value is more easily adjusted accurately. The medium prepared by the improved method was inoculated culture Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa growth are good. For the health inspection of drugs, the result
