WebThe most-probable-number (MPN) method permits estimation of population density without an actual count of single cells or colonies. It is some-times called the method of ultimate or extinction dilution or, less descriptively, simply the dilution method. WebThe method is based on the growth of target organisms in a liquid medium and calculation of the “Most Probable Number” (MPN) of organisms by reference to MPN tables. This method can be applied to all types of water, including those containing an appreciable amount of suspended matter and high background counts of heterotrophic bacteria.
