Chromogenic Coliform Agar (ISO) plates are a fast, accurate, and efficient way to detect coliforms and E.coli during microbiological quality testing of drinking water, disinfected pool water, and treatment plant samples.
• Conforms to ISO 9308-1 guidelines
• Easily and clearly differentiatesE. coliand coliforms
• Ready-to-use convenience of prepared media
• Tested in accordance with the methods described in ISO 7704:2023The guideline, ISO 9308-1:2014 Enumeration of Escherichia coli and coliform bacteria –Part 1: Membrane filtration method for waters with low bacterial background flora, specifies a method based on membrane filtration, subsequent culture on a Chromogenic Coliform Agar medium, and calculation of the number of target organisms in the sample. Chromogenic Coliform Agar (ISO) utilizes specific enzymes associated with general coliforms and E.coli for differentiation.
• The chromogen Salmon GAL, when cleaved by D-galactosidase, produces a pink to red coloration; this coloration and enzyme are associated with coliforms.
• E.colicontains D-galactosidase which cleaves Salmon GAL; however, it also contains D-glucuronidase, which cleaves the chromogen X-glucuronide. The combination of these chromogens produces a dark blue to violet coloration associated withE.coli.Tergitol-7 within the medium inhibits Gram positive bacteria and Gram negative bacteria with exception of coliforms.Not all products are available for sale in all territories.
