m-Endo Agar is used for the enumeration of coliforms in water by the membrane filtration method.
Product Summary and Explanation
The coliform group, especially Escherichia coli, are used as indicators of fecal pollution in water, for assessing the effectiveness of water treatment and disinfection, and for monitoring water quality. m-Endo Agar is prepared according to the formula of McCarthy, Delaney, and Grasso, and used in testing water for coliforms by a two-step membrane filtration procedure. Lauryl Tryptose Broth is used as the preliminary enrichment, resulting in higher coliform counts.
The American Public Health Association (APHA) recommends m-Endo Agar in standard total coliform membrane filtration procedure for testing water, wastewater, and foods. The US EPA specifies using m-Endo Agar in the total coliform methods for testing water. m-Endo Agar is also known as LES (Lawrence Experimental Station) Endo Agar.
