Product number: NCM0015

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. from food. Buffered Peptone Water (BPW) (ISO) is not intended for use in the diagnosis of disease or other conditions in humans.

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 recovery of these organisms.
