RAPID'E.coli 2 Supplement #12008041

Use RAPID'E.coli 2 Selective Supplement with RAPID'E.coli 2 Agar for the direct enumeration of E.coli and coliforms in water intended for human consumption and waste water. RAPID'E.coli 2 Agar for Water Testing is based on the simultaneous detection of β-D-glucuronidase (GLUC) and β-D-galactosidase (GAL) activities. Coliforms (GAL+/GLUC-) form green colonies, whereas for E.coli (GAL+/GLUC+) the combined GAL and GLUC (pink) enzyme activities result in blue to violet colonies. Interfering flora in water is inhibited by the supplement making RAPID'E.coli 2 Agar a good choice for testing water for human consumption and untreated water (such as water from wells, lakes, and rivers) where standard media are often not suitable.
