Buffered Peptone Water is mainly used for the non-selective pre-enrichment of Salmonella spp. from food, for testing a diluent and for water sample testing in a laboratory. This product is not recommended for diagnosis of diseases or other conditions. Buffered Peptone Water is a pre-enrichment medium which aids in the recovery of sub-lethally damaged Salmonellae before it is transferred to a selective medium. This pre-enrichment medium is free from inhibitors and is well buffered and provides conditions for resuscitation of the cells that have been injured by processes of food preservation. Lactose Broth is commonly used as a pre-enrichment medium but it can be detrimental to recovery of Salmonellae. These pre-enrichment media contain peptone as a source of carbon, nitrogen, vitamins and minerals. Sodium chloride maintains the osmotic balance and phosphates buffer the medium. The broth is rich in nutrients and produces high resuscitation rates for sub-lethally injured bacteria and supports intense growth. The phosphate buffer system prevents bacterial damage due to changes in the pH of the medium.
