Neogen® Buffered Peptone Water (BPW) (ISO)

Ready-to-reconstitute media bags for BPW HQ (ISO) contain exactly the correct amount of dehydrated culture media and supplements to prepare 20 L of enrichment broth. The dehydrated culture media contained in each bag has been sterilized via irradiation and needs reconstituting with sterile deionized/RO water.

Buffered Peptone Water (BPW) (ISO) is used for the non-selective pre-enrichment of a variety of microorganisms from food, including Salmonella spp. and Cronobacter spp. It's formulated to ISO 6579-1:2017, ISO 22694:2017, ISO 21528-1:2017, and ISO 12950:2010. This pre-enrichment medium is designed to help sublethally damaged Salmonellae recover before introducing them into a selective medium. This nutrient medium is free from inhibitors and is well buffered to maintain pH 7.0 for the incubation period. Sublethal injury to Salmonellae occurs in many food processes, and this pre-enrichment step greatly increases the recovery of these organisms.
