The most probable number method, otherwise known as the method of Poisson zeroes, is a method of getting quantitative data on concentrations of discrete items from positive/negative (incidence) data. Purpose
An A1 broth is a liquid culture medium used in microbiology for the detection of fecal coliforms in foods, treated wastewater and seawater bays using the most probable number (MPN) method. It is prepared according to the formulation of Andrews and Presnell given below. [1]
Lauryl tryptose broth is used for the most probable number test of coliforms in waters, effluent or sewage. It acts as a confirmation test for lactose fermentation with gas production. Sodium lauryl sulfate inhibits organisms other than coliforms. Formula in grams/litre (g/L) Tryptose: 20.0, Lactose : 5.0, Sodium chloride : 5.0,
Instead of colony-forming units, the parameters Most Probable Number (MPN) and Modified Fishman Units (MFU) [29] can be used. The Most Probable Number method counts viable cells and is useful when enumerating low concentrations of cells or enumerating microbes in products where particulates make plate counting impractical.
