Ürün Açıklaması

Application(s): Industrial, Food, Dairy
Organism(s): Enterobacteriaceae / Coliforms, E.coli, Salmonella /Shigella

A medium for the enumeration of coliform organisms in food and dairy products.

A modification of Violet Red Bile Agar LAB031 introduced by Mossel in 1978. Violet Red Bile Agar (VRBA) LAB031 contains lactose which is fermented by members of the coli/aerogenes group, this medium gives a ‘coliform´ count. Violet Red Bile Glucose Agar (VRBGA) LAB088 has substituted lactose with glucose.

Glucose is fermented by all members of the Enterobacteriaceae family thus VRBGA gives a presumptive Enterobacteriaceae count. Bile salts and crystal violet are used to inhibit Gram-positive and non-enteric organisms. The overlay procedure ensures anaerobic conditions and suppresses the growth of non-fermentative Gram-negative bacteria.
