Buffered Peptone Water is a pre-enrichment medium designed to help recovery of sub-lethally damaged Salmonellae before transfer to a selective medium. It is free from inhibitors, is well buffered and provides conditions for resuscitation of the cells that have been injured by processes of food preservation. Edel and Kampelmacher found that sub-lethal injury to Salmonella can occur due to food preservation techniques involving heat, desiccation, high osmotic pressure, preservatives or pH changes. Buffered Peptone Water used during the pre-enrichment period helps in recovery of injured cells that may be sensitive to low pH. This is important for vegetable specimens, which have low buffering capacity. This medium can also be used for testing dry poultry feed. Buffered peptone water contain proteose 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 sublethally injured bacteria and supports intense growth. The phosphate buffer system prevents bacterial damage due to changes in the pH of the medium.
