Inoculate each container with among the list of ready and standardized inoculum, and blend.

Work out regular CFU of The brand new wide range of media and typical CFU of the Earlier authorised number of media and % recovery by making use of following equation;

1. Don’t expect a microorganism to expand at the same time on selective agar as on non-selective agar (even though the non-selective agar was created for the microorganism species)
