LAURYL SULPHATE BROTH (LAURYL TRYPTOSE BROTH)

Lauryl Sulphate Broth is used for the detection of coliforms in water, dairy products and other foods, as recommended by APHA. Lauryl Sulphate Broth is also recommended by the ISO Committee for the detection of coliforms. It can be used for the presumptive detection of coliforms in water, effluent or sewage by the MPN test. Lauryl Sulphate Broth was developed by Mallmann and Darby. Cowls demonstrated that inclusion of sodium lauryl sulphate makes the medium selective for coliform bacteria. It was later investigated that Lauryl Sulphate Broth gave a higher colon index than the confirmatory standard methods media and also that gas production in Lauryl Sulphate Broth not only acts as a presumptive test but also as a confirmatory test for the presence of coliforms, in the routine testing of water.
