WebChromogenic reagents include the various kinds of chemicals used as pH indicators (for both aqueous and nonaqueous systems), redox indicators, metal indicators, giving changes usually in color but also in fluorescence or luminescence, and reagents used for visual and/or absorptiometric colorimetry. WebThe chromogenic mixture is mainly composed of two substances: 6-chloro-3-indolyl-ß-D-galacto-pyranoside and 5-bromo-4-chloro-3-indolyl-ß-D-glucuronide. The first is cleaved by the characteristic enzyme of coliforms, ß-D-galactosidase and gives a salmon to red colour to the coliform colonies.
