), inoculating Every plate with a little selection (not in excess of one hundred cfu) of the suitable microorganism. Incubate at the specified temperature for not more than the shortest time period laid out in the test. Growth on the microorganism similar to that previously attained by using a Earlier tested and authorized batch of medium occurs. Test for Inhibitory Properties, Liquid or Stable Media— Inoculate the appropriate medium with at least 100 cfu of the suitable microorganism.
Right before a whole new batch of society media is often released for almost any microbiological tests, specially less than pharmaceutical market regulations, it should be thoroughly tested for its capacity to assure dependable and responsible results.
