The micro-organisms are to get included towards the diluted/suspended product at the conclusion of the preparing (usually a 1 in 10 dilution is prepared) or following the neutralization (in the last portion from the rinsing fluid in the case of filtration or concurrently While using the planning in/about the Petri dish in the situation of the plate count method) if inhibition of growth from the sample are not able to otherwise be avoided. The one hundred CFU refers to the inoculum (e.g., what will be on the filter or about check here the plate).
