Buffered Peptone Water

Buffered Peptone Water (7418)

Intended Use

Buffered Peptone Water is specifically formulated for the non-selective pre-enrichment of Salmonella spp. in various food samples.

Product Summary and Explanation

Research has indicated that food preservation methods—such as heating, desiccation, the use of preservatives, and modifications in osmotic pressure or pH—often lead to sublethal injuries in Salmonella spp.. To enhance recovery, pre-enrichment in a non-selective medium is employed, allowing for the repair of compromised cells.

While Lactose Broth is commonly used, it can hinder recovery efforts for Salmonella. Buffered Peptone Water maintains an optimal high pH throughout the pre-enrichment phase, promoting the restoration of injured cells that may be sensitive to low pH levels. This factor is particularly vital when working with vegetable specimens, which tend to exhibit low buffering capacities.

Buffered Peptone Water is utilized in a variety of standardized methodologies, making it an essential component in the microbiological testing of food products. Ensure accurate detection and reliable results with this top-tier pre-enrichment medium.
