Just after inoculation, place the culture media plates or tubes within the designated incubators at the specified temperature and duration mentioned in the SOP.

The colonies are similar in overall look and sign reactions to those Formerly attained by using a Beforehand tested and authorised batch of medium.

The quantity of CFU for The brand new batch needs to be inside of a issue of two of the standard range of colonies within the Earlier approved batch.
