The required microorganisms need to be detected While using the sign reactions as explained under Testing of Solutions.

The target from the Growth Promotion Test should be to reveal the media used to detect the microorganisms is ideal. Laboratories accomplish the test by inoculating new batches of media with a small range of microorganisms. The microorganisms will develop Should the media is suited.

After a specified incubation period of time, observe the tube/flask and report the observations in Annexure I.

You should make use of the strains that are cited During this chapter, or equivalent strains from other culture collections.
