WebResults of the MPN procedure using A-1 medium are reported in terms of the most probable number (MPN) / g calculated from the number of positive A-1 culture tubes and percent total solids (dry weight basis). 3.0. Definitions . 3.1. Fecal coliform bacteria are gram-negative, non-spore-forming rods that are found in the intestines 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.
