Selective For: E. coli and other coliforms
Description: Coliscan® is a clear medium containing two chromogenic substrates. One is cleaved by the enzyme galactosidase (produced almost exclusively by coliforms) to produce an insoluble pink compound. This causes coliform colonies to be pink/red. The second is cleaved by the enzyme glucuronidase (produced almost exclusively by E. coli) to produce an insoluble teal compound. Using the two compounds allows easy visual distinction between general coliforms (pink/red colonies) and E. coli (pink + teal = blue/purple colonies)
