These methods use culture- specific media and elevated temperature to isolate and enumerate fecal coliform organisms. A most probable number method is practised for the qualitative and quantitative water to determine microorganisms’ presence (mainly coliforms). “ MPN ” is an acronym for most probable number. Multiple tube fermentation test or MPN method determines the quality of water by quantifying the number of coliforms in 100 ml of the water sample.
