To complete Growth promotion test on new media good deal, take Anybody media container with the new large amount and carry out test with microorganisms as demonstrated in Desk-I.
The colonies are similar in visual appeal and indication reactions to those Beforehand acquired having a previously tested and permitted batch of medium.
Transfer the sterile tubes/flasks that contains media for the LAF bench and get more info allow it to chill to area temperature.
The growth promotion test is a high quality Manage requirement that confirms the flexibility of a completely new batch of media to aid growth of the predetermined array of agent microorganisms.
