Presumptively identify coliform organisms in milk, water and foods as specified by the American Public Health Association1,2,3 with Thermo Scientific™ Oxoid™ Lactose Broth (Dehydrated). Beef extracts and peptone in this liquid medium supply essential nutrients while lactose is a fermentable carbohydrate for coliforms. Coliforms ferment lactose in the medium resulting in gas formation which is indicative of positive results.
Tubes of Lactose Broth are inoculated with dilutions of the samples and incubated at 35°C. Examination for gas formation is carried out after 24 and 48 hours incubation. This presumptive evidence of coliform organisms must be confirmed by further tests.
