11. Test strains should be inoculated independently working with many micro-organisms equivalent to not more than one hundred CFU, could you explain if Consequently only the specific micro-organism less than detection in the test method is inoculated into your growth medium or if Each individual of the 4 microorganisms are extra independently into the growth medium for each of the precise test methods?
Offered the critical mother nature of microbiological high quality tests used to make sure the protection of pharmaceutical goods for human use, it is essential to undertake QC tests confirming the media applied is suit for goal.
