This agar is designed for the enumeration and differentiation of coliforms and Escherichia coli (E.coli) in water samples, adhering to ISO 9308-1 guidelines. It provides fast and accurate results within 24 hours, eliminating the need for subculturing.

Differentiation is clear: E.coli forms dark blue/violet colonies (due to D-galactosidase and D-glucuronidase cleaving chromogens), while coliforms produce pink to red colonies (from D-galactosidase activity on Salmon GAL). Tergitol-7 inhibits most Gram-positive and other Gram-negative bacteria, ensuring selectivity.
