Previous to launch for use, batches of the media for use for APS must be reconstituted and sterilized; then samples really should be subjected to quality Regulate testing for growth promotion by inoculating with ≤ one hundred colony-forming units of consultant compendial strains of microorganisms. Microorganism strains from environmental monitoring may be included in the growth promotion test.

Reliable media is ideal when count is not really larger than 2 from your calculated worth of the standardized worth.

Good Medium Acceptance Criteria – Regular the number of colonies from your new batch of medium and the amount of colonies in the Beforehand approved batch of medium. For the new batch of medium to get approved, the subsequent acceptance criteria has to be achieved for each microorganism tested:
