Growth promotion test (GPT): Also referred to as fertility or nutritive properties test, which can be performed within the media used through distinctive tests like sterility test, microbial Restrict test, preservative efficacy test to display that it's able to supporting the growth of micro-organisms
Monitor and assess duties to ensure compliance with regulatory demands and retain product or service quality
Determine average CFU of The brand new large amount of media and ordinary CFU of your Formerly authorized number of media and % recovery through the use of subsequent equation;
The just lately harmonized Microbial Restrictions Tests (USP 2003b, USP 2003c) extend the requirements to an analysis from the differential and selective Houses with the media, Along with confirming the nutritive Qualities. Lastly, the proposed USP chapter on microbiological laboratory techniques stresses the need to adequately Handle the growth media (USP 2004). None of such documents, on the other hand, provides in depth info on how to ascertain the general excellent characteristics of media.
