MRS Agar and Broth were designed to encourage the growth of the & acid bacteria’ which includes species of the following genera: Lactobacillus, Streptococcus, Pediococcus and Leuconostoc. All these species can produce lactic acid in considerable amounts. They are Gram-positive, catalase and oxidase negative and are fastidious in their nutritional requirements.
De Man, Rogosa and Sharpe agar, often abbreviated to MRS, is a selective culture medium designed to favour the luxuriant growth of Lactobacilli for lab study. Developed in 1960, this medium was named for its inventors. It contains sodium acetate, which suppresses the growth of many competing bacteria (although some other Lactobacillales, like Leuconostoc and Pediococcus, may grow). This medium has a clear brown colour.

Previous media for the cultivation of lactobacilli employed the use of tomato juice, however, tomato juice agar was undesirable because of its variability and difficulty in preparation. A media described by Rogosa, Mitchell and Wiseman, although adequate for most lactobacilli, was found to be unsatisfactory for use with some dairy lactobacilli organisms
