///BM0980 – Violet Red Bile Glucose Agar(VRBGA)

BM0980 – Violet Red Bile Glucose Agar(VRBGA)

A modification of Violet Red Bile agar designed to give a ‘coliform’ count. In this medium lactose is substituted with glucose. Glucose is fermented by all members of the Enterobacteriaceae thus V.R.B.G.A gives a presumptive Enterobacteriaceae count. Bile salts and crystal violet are used to inhibit Gram positive and non-enteric organisms. The growth of non-fermentative Gram negative bacteria can be suppressed by using the agar overlay method.
