Product Code TM 483
Violet Red Glucose Bile Agar is used for the detection and enumeration of Enterobacteriaceae in food, animal feed and environmental samples. This medium is a modified form of Violet red bile lactose agar, which was formulated by Mossel et al by replacing lactose with glucose to improve the recovery of all Enterobacteriaceae. In this medium, Enterobacteriaceae rapidly ferment glucose and so reduce the pH of the medium, which produces purple/pink coloured colonies due to the inclusion of the neutral red indicator and crystal violet in the medium. The composition & performance criteria of this medium are as per the specifications laid down in ISO 21528.
