Question

Quizplus · Accepted Answer

The Most Probable Number (MPN) method is used to estimate numbers of cells in samples with a low density of bacterial cells. This method involves dilution of the sample and inoculation into multiple tubes or wells, with subsequent observation for growth. The MPN can then be calculated based on the number of tubes or wells that show growth at each dilution level.
