In case the microorganisms increase very well over the medium, it truly is considered to be a good quality medium, and may be used for microbiological testing. If there isn't a growth or bad growth of microorganisms, it implies that the medium may very well be contaminated or of weak excellent, and shouldn't be utilized for testing.
The TSB tubes are incubated below suitable conditions, and just after incubation, the tubes showing growth are counted. The bacterial count in the first sample can then be calculated based upon the dilution variables.
