Buffered Peptone Water for Pre-enrichment of Salmonella spp., 500 g, Acumedia 7418A

Acumedia® Buffered Peptone Water for Pre-enrichment of Salmonella spp., 500 g, 7418A

Features:

• Buffered Peptone Water (BPW) is used for non-selective pre-enrichment of Salmonella spp. from food and is not intended for use in diagnosis of disease or other conditions in humans
• 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 non-selective medium allows for repair of cell damage and facilitates recovery of Salmonella
• Lactose Broth is frequently used for this purpose, but it may be detrimental to recovering Salmonellae
• Buffered Peptone Water maintains high pH over
• 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 low buffering capacity
• Appearance: beige powder
• pH: 7-7.4
• Flammability (solid, gas): not flammable
• Solubility: soluble in water
