), inoculating Just about every plate with a little number (not greater than one hundred cfu) of the appropriate microorganism. Incubate at the desired temperature for the stretch of time inside the selection specified in the test. Colonies are similar in physical appearance and sign reactions to All those Earlier obtained having a Beforehand tested and authorized batch of medium.
At our facility, we do not conduct pour plates on MacConkey agar. If you suspect the microorganism is the cause of no growth, you should electronic mail techsupport@microbiologics.com with this concern and we will likely be joyful to research this more.

The a hundred CFU refers to the inoculum (e.g., what's going to be about the filter or on the plate).
