eleven. Test strains must be inoculated separately utilizing many micro-organisms comparable to not a lot more than a hundred CFU, could you make clear if Therefore only the precise micro-organism underneath detection inside the test method is inoculated in the growth medium or if Each and every with the 4 microorganisms are extra separately on the growth medium for each of the precise test methods?
Biochemical testing: TSB can function a foundation medium for carrying out different biochemical tests to establish or characterize bacterial isolates.
The concentration of an added antimicrobial preservative is often kept at a bare minimum When the Lively substances in the formulation possess an intrinsic antimicrobial exercise.
