Bile Salts No. 3, Microbiology Grade, 10kg is a bulk reagent used for preparing microbiological media designed to isolate and differentiate enteric bacteria. The high purity of these bile salts makes them essential for selective bacterial growth in food safety, clinical microbiology, and environmental monitoring. This large quantity is ideal for laboratories that require frequent preparation of selective media in large volumes. Bile Salts No. 3 works by inhibiting the growth of non-enteric bacteria while allowing enteric pathogens such as Salmonella, Shigella, and Escherichia coli to thrive. It is commonly used in bacteriological testing of water, food, and clinical specimens.
