Quantité:
A differential medium recommended for the presumptive identification of Escherichia coli and other coliforms in food and environmental samples. The medium contains two chromogens. One of the chromogen is cleaved by the enzyme glucuronidase produced by Escherichia coli to give blue to purple coloured colonies whereas the other chromogen is cleaved by the enzyme galactosidase, produced by majority of coliforms, resulting in the formation of rose-pink coloured colonies.
