Descripción

Application

ECC ChromoSelect Agar is a differential medium recommended for the presumptive identification of Escherichia coli and other coliforms in food and environmental samples. The chromogenic mixture containstwo chromogens as X-glucuronide and Salmon-GAL. X-glucuronide is cleaved by the enzyme beta glucuronidase produced by Escherichia coli. Salmon-GAL is cleaved by the enzyme galactosidase produced by majority of coliforns, including Escherichia coli. Color of E. coli colonies: blue/purple

Preparation Note

Suspend 55.8 g in 1 litre distilled water. Sterilize by autoclaving at 121°C for 15 minutes. Cool to 50°C and pour into sterile petri plates
