  • Description

    Chromogenic ECC Selective Agar, Modified is a selective medium recommended for the simultaneous detection of Escherichia coli and total coliforms in water and food samples. The chromogenic mixture contains two chromogenic substrates. The enzyme ?-D-galactosidase produced by coliforms cleaves one of the chromogen to form salmon to red coloured colonies. The enzyme ?-D-lucuronidase produced by E.coli, cleaves X-glucuronide, the other chromogen. Colonies of E.coli give dark blue to violet coloured colonies due to cleavage of both the chromogens.
