When in -house prepared microbiological media are properly prepared andsterilized using a validated method, the growth-promotion testing maybe limited to each incoming lot of dehydrated media ,unless otherwiseinstructed by the relevant compendial method .If the media preparationwas not validated , then every batch of media would be subjectedto groth-promotion testing .
在本段的前半句中提到 properly prepared and sterilized using a validated method，只要是合适的并且灭菌过程中经过验证的配制，促生长试验可放宽至一个干粉培养基的批号。
后半句则说media preparation was not validated ，培养基的配制未经过验证，则每个配制批次的培养基需做促生长试验！
而实验室中的灭菌过程肯定是经过验证的啊，第一次用培养基做灭菌器的满载试验时就做过的啊 那是否就如前半部份所说的，每个干粉培养基的批次做一次促生长试验就可？ 7OuzQzhcK },1**_#<Br )HZUCi/F] -I, _{3. S doR'E= Z4h X,- 'v[z C9-9cdWH $ql-"BB tYfhKJzGC F dv&kK!
