Universal Preenrichment Broth
Universal Pre-enrichment Broth is a non-selective medium used for the recovery of Salmonella and Listeria from food products. With traditional methods requiring different pre-enrichments for each microorganism, Universal Pre-enrichment Broth was formulated by Bailey and Cox for the recovery of sublethally injured strains of both Listeria and Salmonella from a single food product specimen. The medium is well buffered, containing Disodium and Monopotassium Phosphates, which allows the recovery of pH-sensitive bacteria. Enzymatic Digest of Casein and Protease Peptones supply necessary growth nutrients such as amino acids, peptides, vitamins, and electrolytes. Dextrose is an energy source to sustain bacterial growth. Sodium Chloride, Magnesium Sulfate and Ferric Ammonium Citrate provide essential electrolytes and maintain the osmotic equilibrium. Sodium Pyruvate stimulates the metabolism of stressed microorganisms.
