Description

General description

Buffered Peptone water is a nutrient broth media that aids in resuscitating sub-lethally injured bacteria and enables intense growth. The phosphate buffer system prevents bacterial damage caused by changes in the pH of the medium. Peptone, including enzymatic digest of casein acts as a source of carbon, nitrogen, vitamins, and minerals whilst sodium chloride maintains the osmotic balance. The Readybag^® sachets are gamma-irradiated (10-20 kGray). Each Readybag^® sachet contains 86 g of granulated Buffered Peptone Water broth, which can be reconstituted on addition of sterile water.

Application

Readybag^® Buffered Peptone Water is suitable for the preliminary non-selective enrichment of bacteria, particularly pathogenic Enterobacteriaceae, such as Salmonella and Cronobacter, from food and animal feed, water, and other materials.
