Buffered Peptone Water for Salmonella Pre-Enrichment Testing

Description

Buffered Peptone Water (BPW) is a premium pre-enrichment medium designed to recover injured Salmonella species from food samples. It creates ideal conditions for Salmonella recovery before transferring to selective media. This makes BPW an essential tool in food safety testing and microbiological analysis.

BPW contains a well-balanced mix of peptone, sodium chloride, disodium phosphate, and monopotassium phosphate. This ensures a stable pH of 7.2 ± 0.2 at 25°C, promoting the repair of injured bacteria. These ingredients work together to enhance bacterial growth and improve detection accuracy. As a result, food safety laboratories and researchers worldwide rely on BPW. It helps detect even the smallest bacterial contamination in food.

Key Benefits:

• Salmonella Recovery: BPW significantly improves the recovery rate of injured Salmonella, making it ideal for food safety applications.
• Balanced Formula: The mix of peptone and phosphates maintains an optimal pH, supporting bacterial recovery.
• Versatile Use: BPW is suitable for testing a variety of food products, especially those under stress during processing, such as meat, dairy, and produce.

Directions for Use:

Dissolve 20.0g of Buffered Peptone Water in 1 liter of distilled or deionized water. Stir frequently until fully dissolved. Sterilize by autoclaving at 121°C for 15 minutes at 15 psi. Store in a dry, dark place to ensure product effectiveness.

Why BPW Matters:

Buffered Peptone Water is vital for food microbiology testing. It allows for the early detection of Salmonella and boosts the chances of finding contaminated samples. BPW provides a dependable environment for pathogen pre-enrichment, leading to faster and more accurate results in foodborne pathogen testing.
