How to calculate mpn.

Introduction . For the convenience of analysts using the procedures in this Guidebook, tables of Most Probable Numbers (MPN) are provided in this appendix. MPN is a procedure to estimate the population density of viable microorganisms in a test sample.What we want to know is the “most probable number (MPN)”, the density which maximizes the probability of obtaining the observed result. Such a density is obtained by finding root of the derivative of log likelihood function. Therefore, the MPN is given by the root of the following equationMPN: MPN - Frequently Asked Questions.
