eleven. Test strains has to be inoculated independently applying several micro-organisms reminiscent of not a lot more than a hundred CFU, could you make clear if Because of this only the particular micro-organism less than detection inside the test method is inoculated in the growth medium or if Every of the four microorganisms are additional separately into the growth medium for each of the precise test methods?
