No. Often selective media has inhibitory attributes. To meet pharmacopeial demands, the volume of colonies on the new batch of selective media only has to be akin to the quantity of colonies recovered on the Earlier authorised batch.
Calculate typical CFU of the new large amount of media and ordinary CFU on the Formerly authorized wide range of media and % Restoration by using subsequent equation;
Suitability needs to be verified if a change in testing overall performance or perhaps a alter within the solution which could have an effect on the result in the test is introduced.
