Descripción

Descripción general

Violet Red Bile Dextrose (VRBD) Agar settle plates are used for the detection and enumeration of Enterobacteriaceae and bile-tolerant Gram-negative bacteria. Crystal violet and bile salts inhibit the accompanying bacterial flora. Fermentation of glucose by Enterobacteriaceae leads to acid production, which is indicated by a color change to red and by zones of precipitated bile acids surrounding the colonies. Enzymatic digest of animal tissue provides carbon and nitrogen sources for the growth, and yeast extract primarily supplies the B-complex vitamins. The culture medium is not specific for Enterobacteriaceae as some other accompanying bacteria (e.g. Aeromonas) also show the same reaction.

Aplicación

Violet Red Bile Dextrose (VRBD) Agar settle plates are used to detect and enumerate Enterobacteriaceae from food, animal feed, and other materials. They are also suitable for the enumeration of bile-tolerant Gram-negative bacteria from pharmaceuticals and other materials.
