General coliforms produce the enzyme galactosidase in lactose fermentation and E. coli produces the enzyme glucuronidase in addition to galactosidase.
Coliscan takes advantage of these facts to give you a simple, accurate and quantitative way to identify and differentiate coliforms and E. coli (true fecal coliform) from other bacteria in water or other types of samples. This patented method incorporates two special chromogenic substrates which are acted upon by the presence of the enzymes galactosidase and glucuronidase to produce pigments of contrasting colors. All that is needed to identify the presence and numbers of coliforms and E. coli is to add a test sample to the medium, pour it into a petri dish and incubate it at room temperature or at a higher controlled temperature (35 ° C is suggested).
