), inoculating Every plate with a small quantity (not in excess of one hundred cfu) of the right microorganism. Incubate at the required temperature for a length of time in the assortment specified in the test. Colonies are comparable in appearance and indication reactions to People Beforehand received that has a Formerly tested and authorised batch of medium.
With more than thirty-five years’ practical experience in manufacturing Redipor® ready media, Cherwell has in-depth Perception and expertise that makes sure it continually provides prepared media of the best calibre to its consumers.
The objective of the Growth Promotion Test is to exhibit the media used to detect the microorganisms is suited. Laboratories execute the test by inoculating new batches of media with a small range of microorganisms. The microorganisms will increase if the media is suitable.
Following a specified incubation period, notice the tube/flask and file the observations in Annexure I.
When parallel testing is made use of, the new and previously authorised batches on the medium has to be inoculated Along with the exact same inoculum, by precisely the same technician, and are subjected to similar incubation disorders. The one variable could be the medium.
