CRITERION Violet Red Bile Agar with MUG, Dehydrated Culture Media, 500g

CRITERION Violet Red Bile Agar with MUG (VRBA-MUG) is a selective and differential dehydrated culture medium designed for the detection and enumeration of coliform bacteria and Escherichia coli in food, dairy products, and water samples. The incorporation of 4-methylumbelliferyl-β-D-glucuronide (MUG) enables rapid identification of E. coli through fluorescent detection under UV light, while the violet red bile formulation inhibits gram-positive microorganisms and promotes the growth of bile-tolerant gram-negative bacteria. This medium is essential for quality control laboratories performing routine microbiological testing in compliance with standard methods.
