There happen to be reports and worries about variances in these values obtained working with unique sampling methods, media variability, and incubation temperatures.
Just after getting The brand new whole lot media, numbering shall be performed for all of the media containers According to SOP Media management.
Test a nonselective media for instance TSA in parallel With all the new and Beforehand authorised batches of selective media if you want to make sure you inoculated the media with no more than 100 CFU.
