* Liquid and stable media are sterilized employing a validated method. These media are commercially readily available in dehydrated kind.
Review visually, the colonies figures on the new media agar plates Together with the colonies characters on the Beforehand authorised media agar plates as per annexure-two, Growth Advertising and marketing, inhibitory and Indicative Homes of Media.
The lately harmonized Microbial Limitations Tests (USP 2003b, USP 2003c) expand the requirements to an evaluation on the differential and selective Houses of the media, in addition to confirming the nutritive Qualities. Eventually, the proposed USP chapter on microbiological laboratory practices stresses the necessity to sufficiently control the growth media (USP 2004). None of those documents, nonetheless, gives in-depth information on how to determine the general high quality attributes of media.
ANTIMICROBIAL Usefulness TESTING Antimicrobial preservatives are substances added to nonsterile dosage sorts to safeguard them from microbiological growth or from microorganisms that are released inadvertently all through or subsequent to your manufacturing approach.
Controlled Atmosphere—Any place within an aseptic procedure technique for which airborne particulate and microorganism ranges are controlled to distinct concentrations, acceptable to your activities performed within just that atmosphere.

The compendia believe a GP test by comparison of CFU, with the cells plated in the traditional manner with the lab. The compendia generally have to have which the colony counts derived from growth on The existing batch of media be no fewer than 50% (USP 2003b) or 70% (USP 2004) of the Earlier qualified batch.
