Details

Violet Red Bile Agar with X-GLN contains peptone to provide vitamins and minerals, as well as a carbon and nitrogen source. Yeast extract promotes bacterial growth by supplying B-complex vitamins. Lactose provides a carbohydrate source. Bile salts and crystal violet aid in the inhibition of Gram-positive bacteria. Neutral red is a pH indicator in which lactose-fermenters will produce red colonies and halos (due to bile precipitation). Sodium chloride conserves osmotic balance. X-glucuronide is a chromogenic substrate for β-glucuronidase. Agar is a solidifying agent.
The presence of β-glucuronidase differentiates most E. coli from other coliforms. The formed E. coli colonies are colored blue.
