New Coliform Medium for Milk
Jan 30 2008
Used in conjunction with the Most Probable Numbers (MPN) technique, Modified Lauryl Sulphate Tryptose Broth (ISO) is used as a confirmatory test for lactose fermentation and gas production for presumptive coliforms. The addition of MUG to the medium allows the positive discrimination of E.coli strains. As the majority of E. coli harbour the glucuronidase enzyme, they can use MUG as a substrate, releasing a fluorogenic compound. Tubes which fluoresce under UV are confirmed for E.coli by a positive indole reaction when Kovacâs reagent is added to the tube.
