Selective For: Total coliforms
Description: Coliform is a clear medium with one chromogenic substrate for the differentiation of general coliforms. (Due to the production of galactosidase.) Coliform colonies will be teal/green. This product does not differentiate E. coli from other coliforms. (To differentiate E. coli from other coliforms, use Coliscan®)
Composition: Violet red bile nutrients without VRB dyes, plus a chromogenic substrate to identify galactosidase activity. pH 7.3 ± 0.2
Use standard methodology for product being tested.
Incubation times and temperatures:
For total coliforms:
15-24 hrs at 35°C.
For fecal coliforms only:
15-24 hrs at 44.5°C.
Under optimal conditions, it is possible to take accurate preliminary readings at 15 hours incubation time. Colors will intensify and colony size will be larger at 24 hours.
Interpretation: General coliforms will have a blue-green overall colony color. Proteus, Salmonella, and Shigella will generally grow as white colonies. Other non-coliform colonies are generally inhibited.
