The broth may be used for the detection and enumeration of micro organism, along with for maintaining bacterial cultures and conducting susceptibility testing.
Acceptance criteria: The average CFU of the new batch of media ought to be similar to the typical CFU in click here the batch of Formerly accepted media.
Not enough selectivity: TSB is a non-selective medium, which means it does not incorporate precise inhibitors or selective brokers to inhibit the growth of sure bacteria whilst selling the growth of Some others.
Bacterial growth promotion test: TSB may be used To judge the flexibility of the medium or growth ailments to guidance bacterial growth. With this test, a small inoculum in the microorganisms of interest is included to TSB and incubated at the right temperature and situations.
