The identification of microorganisms is built using a variety check here of strategies. For that identification of bacteria, observation of colony morphology, Gram staining, together with other differential staining for learning mobile morphology and executing distinct biochemical tests is generally done.
You would not have to implement an inhibitory strain to be able to test the suitability of the method. For instance should you test the suitability of the method for E. coli, you should use only E. coli as test micro-organism for development advertising.
