Use Buffered Peptone Water Broth as a nonselective medium for pre-enrichment of bacteria such as Listeria including L. monocytogenes, Salmonella, Cronobacter (Enterobacter), and thermophilic Campylobacter spp. The use of this nonselective broth permits recovery of bacteria after sublethal injury caused by heat, preservatives, or other processing techniques. Features and Benefits Phosphate buffering maintains high pH, allowing repair of species that are sensitive to low pH Rich broth aids in recovery and supports high levels of growth For standardizing test samples and to determine dilutions 225 ml hydrated broth is sufficient for enriching 25 g of sample
