Colonies are equivalent in overall look and sign reactions to These Beforehand acquired using a Formerly tested and approved batch of medium.
Transfer the bacterial cultures, media’s and streaking loops In the sub culturing room beneath Biosafety cabinet.
The growth of microbes is monitored about a specified length of time, normally by measuring optical density or observing colony development on agar plates.
Good Medium Acceptance Criteria – Common the amount of colonies through the new batch of medium and the amount of colonies from your Earlier permitted batch of medium. For the new batch of medium to be accredited, the following acceptance criteria have to be satisfied for every microorganism tested:
