Buffered Peptone Water is used for the non-selective pre-enrichment of Salmonella spp. from food.
Product Summary and Explanation
Edel and Kamelmacher found that food preservation techniques involving heat, desiccation, preservatives, high osmotic pressure, or pH changes cause sublethal injury to Salmonella spp. Pre-enrichment in a non-selective medium allows for repair of cell damage and facilitates the recovery of Salmonella. Lactose Broth is frequently used for this purpose, but it may be detrimental to recovering Salmonellae. Buffered Peptone Water maintains a high pH over the pre-enrichment period and allows in repair of injured cells that may be sensitive to low pH.This is particularly important for vegetable specimens which have a low buffering capacity. Buffered Peptone Water is used in standard methods.
