Thermo Scientific™ Oxoid™ Violet Red Bile Agar

Description

• Detect and enumerate coliform organisms in water, food and dairy products with Thermo Scientific™ Oxoid™ Violet Red Bile Agar (Dehydrated)
• This lactose containing selective medium has been used for the determination of the coli-aerogenes content of water, milk and other dairy products, dairy equipment, and food products 1,2
• Due to the addition of selective inhibitory components, neutral red, crystal violet, and bile salts, the medium provides selectivity against non-target Gram-positive bacteria
• Use Violet Red Bile Agar for examination of food, animal feed, and environmental samples for the presence of indicator groups such as coliforms
• Besides safety, indicator groups provide a measure of food quality and spoilage potential
• One of the most common groups of bacteria employed as indicator organisms by the food industry are the coliforms, which can be regarded as a subgroup within the Enterobacteriaceae
• Easy-to-read: organisms rapidly fermenting the lactose (coliforms) form red-purple colonies with red-purple halos; while late lactose fermenters form pale colonies with greenish halos
• Selective: crystal violet and bile salts suppress the growth of non-target Gram-positive bacteria
• 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 Violet Red Bile Agar was suitable for determining the coli-aerogenes content of milk
