Tryptose Lauryl Sulfate is a selective medium for the detection of Escherichia coli and coliforms in water and wastewater, milk and dairy products, and other foodstuffs, using the Most Probable Number technique, according to many microbiological standard methods like ISO4831, ISO7251 and ISO11866. The broth recipe was created by Mallmann & Darby in 1941. The principle of the medium relies on the ability of coliforms to ferment lactose with the production of acid and gas. Due to the presence of sodium lauryl sulfate, the medium inhibits bacteria other than coliforms. Inhibition of sporulated aerobic bacteria is total. This medium can also be used with the addition of tryptophane and MUG for the specific detection of Escherichia coli.
