## Overview

Violet Red Bile Agar (VRBA) is a specialized growth medium designed for the isolation and enumeration of coli-aerogenes in various food products, including water and dairy. This formulation, a modification of MacConkey's original, utilizes selective components to suppress unwanted organisms while facilitating the identification of lactose-fermenting bacteria.

## Description

## Features

- Violet Red Bile Agar for isolation and enumeration of coli-aerogenes in water, milk and other dairy food products.
- The historical definition of this group has been based on the method used for detection i.e. lactose fermentation.
- This group is defined as all aerobic and facultative anaerobic, gram-negative, non-spore-forming rod shaped bacteria that ferment lactose with gas and acid formation within 48 hour at 35°C. Examination of foods, ingredients and raw materials, for the presence of marker groups such as coliforms is the one of the common tests.
- Violet Red Bile Agar, a modification of MacConkey original formulation is used for the enumeration of coli-aerogenes bacterial group.
- . It relies on the use of the selective inhibitory components crystals violet and bile salts and the indicator system lactose, and neutral red.
- The growth of many unwanted organisms is suppressed, while tentative identification of sought bacteria can be made.
- Organisms, which rapidly attack lactose, produce purple colonies surrounded by purple halos. Non fermenters or late lactose-fermenters produce pale colonies with greenish zones.
- VRBA is recommended by APHA. Selectivity of VRBA can be increased by incubation under anaerobic conditions and/ or at elevated temperature, i.e. equal to or above 42°C.
