Lab M Launches New Coliform Medium for Milk
|E. coli use MUG as a substrate, releasing a fluorogenic compound|| |
Microbiology specialist Lab M is introducing a new medium for the enumeration of presumptive Escherichia coli in milk and milk products.
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 Kovac's reagent is added to the tube.
