Principle
- Buffered peptone water is composed of peptone, sodium chloride, sodium phosphate dibasic, and monobasic potassium phosphate. Peptone serves as the source of nitrogen, carbon, and other growth factors. Dibasic sodium phosphate and monobasic potassium phosphate act as buffering agents and sodium chloride maintains the osmotic balance.
- Buffered peptone water is designed to help the recovery of the sub-healthy or damaged Salmonella from processed food samples before transferring to a selective medium. Buffered peptone water has shown higher recovery of Salmonella than that of the Lactose broth.
