Acceptance criteria: The growth (turbidity) from the tube of the new batch of media ought to be comparable to the batch of Beforehand permitted media.
All media Employed in a cGMP facility needs to be tested, together with media for microbial more info limitations, environmental monitoring and sterility testing
Prior to a product may be tested, the laboratory need to know if the medium it really is making use of to the test will expand the specified microorganism if it is existing in smaller figures.
