Question

what is the principal of MPN?

Answer 1

Most Probable Number (MPN)  is a method used to estimate the concentration of viable microorganisms in a sample by means of  replicate liquid broth growth in ten-fold dilutions. It is commonly used in estimating microbial populations in soils, waters, agricultural products and is particularly useful with samples that contain particulate material that interferes with plate count enumeration methods.
