Coli (EC) Broth

Description

EC Medium is a culture medium for the detection of coliform bacteria at 35°C and of Escherichia coli at an elevated temperature (44.5 or 45.5°C).

EC Medium is recommended for use in the fecal coliform Most Probable Number (MPN) procedure for the examination of water, wastewater and foods. The procedure employing EC Medium provides information regarding the source of the coliform group (fecal or nonfecal) when used as a confirmatory test. It should not be used for the direct isolation of coliforms since prior enrichment in a presumptive medium for optimal recovery of fecal coliforms is required.
