Violet Red Bile (Lactose) Agar (Powder)

A standard methods, lactose-containing selective medium for selective detection of Coliform in water, dairy products and other food materials. The medium has been used for the determination of the coli-aerogenes content of water, milk and other dairy products, dairy equipment, and food products etc 1,2. Organisms which rapidly attack lactose produce purple colonies surrounded by purple haloes. Non-lactose or late-lactose fermenters produce pale colonies with greenish zones. Other related Gram-negative bacteria may grow but can be suppressed by incubation at >42 degree C or by anaerobic incubation. Druce et al.3 found that Violet Red Bile Lactose Agar was as good an indicator of coli-aerogenes bacteria in milk as MacConkey Broth, and that the medium was suitable for determining the coli-aerogenes content of milk.

Small volumes of Violet Red Bile culture media vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage.
