Lab M's Modified Lauryl Sulphate Tryptose Broth with MUG and Tryptophan (ISO) is designed for the presumptive enumeration of E coli from milk and milk products.
Used in conjunction with the Most Probable Number (MPN) technique and in accordance with ISO 11866-1:2005, Modified Lauryl Sulphate Tryptose Broth with MUG and Tryptophan (ISO) allows presumptive E coli to be enumerated from presumptive coliforms.
The addition of MUG to the Lauryl Tryptose broth formulation allows the positive discrimination of E coli strains.
Tubes that fluoresce under UV light are confirmed for E coli by a positive indole reaction when Kovac's reagent is added to the tube.
