General description

m-ColiBlue24® broth is recommended for simultaneous detection of total coliform bacteria and Escherichia coli (E. coli) in water samples within 24 hours. An enzymatic indicator in the medium causes non-fecal total coliform colonies grown on the m-ColiBlue24® medium to be red, while the E. coli (fecal coliform) colonies are blue. The selectivity of the enzymatic indicator eliminates the need for confirmation. The low false positive and false negative rates allow for the detection of at least 95% of all E. coli. m-ColiBlue24® Broth enhances the growth rate of coliform bacteria. Special inhibitors in the medium efficiently minimize the growth of non-coliform bacteria.

Application

m-ColiBlue24® broth is used for monitoring drinking water, wastewater, and other types of water using a 24 hour incubation period. It can also be used to detect coliforms in other types of water—bottled, surface, ground, well, recreational (fresh or marine), as well as process water for ultrapure chemical processing.

Features and Benefits

  • Ready-to-use Liquid ampoule media solve numerous problems in microbiology laboratories where time, equipment, and trained personnel are often in short supply.
  • They are available in convenient, single-test 2 mL plastic ampoules, eliminating the manipulation of glass ampoules and avoiding the waste and spoilage associated with bulk packaged media.
