Compact Dry CF is an easy tool for the detection of coliforms. Coliforms grow with blue/blue green colonies as the recipe contains the chromogenic enzyme substrate X-GAL. The growth of bacteria other than coliforms is mainly inhibited but in case of growth they form colorless colonies. Compact Dry CF is AOAC, MicroVal und NordVal approved.
