MRS Broth

Descrição detalhada : MRS Broth is used for the enrichment, cultivation, and isolation of all species of Lactobacillus from all types of material according to DeMan, Rogosa, and Sharpe. The medium can be used for confirmatory tests of colonies isolated from MRS Agar. The MRS culture media contain polysorbate (Tween 80), acetate, magnesium, and manganese which are known to act as special growth factors for Lactobacilli as well as a rich nutrient base. As these media show a very low degree of selectivity Pediococcus and Leuconostoc species, as well as other secondary bacteria, may grow on them. Most of the accompanying microflora can be inhibited by thallium acetate, sorbic acid, acetic acid, sodium nitrite, cycloheximide, and polymyxin. These substances can be used at varying concentrations and combinations, but inevitably a compromise must be reached between selectivity and recovery rate of the organism.
