SEOH Violet Red Bile Glucose Agar Dehydrated Media 500g

Violet Red Bile Glucose Agar is recommended for use in the microbiological analysis of food. Violet Red Bile Glucose Agar is a selective medium which detects the growth of glucose fermenting Gram negative bacteria. The glucose fermenting bacteria lower the pH of the medium subsequently causing their colonies to look red (neutral red dye) and to precipitate the bile salts. Crystal violet and bile salts inhibit the growth of Gram positive microorganisms.. Instructions for use and preparation are provided as well as a Certificate of Analysis.
