sangat perlu dilakukan karena setiap bets media maupun setiap merek media yang berbeda terdapat perbedaan jumlah pertumbuhan mikroba, karena hal tersebut untuk menentukan media yang cocok maupun media yang masih layak pakai.
1. The average number of colonies on the new batch from the medium should be “similar” to the typical number of colonies about the previously approved batch. A quantitative definition of “similar” isn't established from the USP, Ph. Eur. or JP.
This is certainly confirmed by identification tests. The product complies Along with the test if colonies of the categories explained are usually not existing or if the confirmatory identification tests are negative.
five. Does it ought to be performed whenever the item is tested or in the method validation or could it be feasible to get it done periodically?
