eleven. Test strains must be inoculated separately employing a number of micro-organisms equivalent to not greater than 100 CFU, could you explain if Consequently only the specific micro-organism beneath detection within the test method is inoculated in the growth medium or if Every single from the 4 microorganisms are extra separately on the growth medium for every of the specific test methods?
