SUMMARY: A modification of the dulcitol‐lactose‐iron medium of Taylor & Silliker (1958) is proposed. It contains sucrose as well as lactose to aid in detecting slow lactose fermenters and gives simultaneously tests for urea hydrolysis and H 2 S production. The latter reaction is kept apart from the carbohydrate fermentations and the urea hydrolysis. The surface growth can be used in a test for the deamination of phenylalanine to phenylpyruvic acid.
