Growth promotion should be tested for each new batch of medium. Growth promotion has to be checked on agar media and nutritive broth although not on diluted broth.
Weigh and dissolve the ingredients: Evaluate out the appropriate quantities of each ingredient based upon the desired quantity of TSB.
Transfer the bacterial cultures, media’s and streaking loops In the sub culturing home beneath Biosafety cabinet.
Growth received ought to not be differing by an element larger than two from your calculated value for standardized inoculums for Stable Media, For freshly organized inoculums, growth from the micro-organisms comparable to that previously attained that has a previously tested and authorized batch of medium happens.
Routinely monitor the cultures for growth, noting any observations or abnormalities. This will help you establish Should the growth promotion test is productive or if any difficulties need to be resolved.

Colony sizing: The size of bacterial colonies on TSA can vary from smaller pinpoint colonies to huge colonies, dependant upon the bacterial species and growth disorders.
Just a little experimentation could possibly be required to pick the most effective media and growth conditions for hard-to-expand environmental isolates for example
Acceptance criteria: The colonies characters on the new media agar plates should be similar Together with the colonies figures on the Formerly authorised media agar plates.
