MacConkey Agar Powder – Selective Medium for Gram-Negative Bacteria

What is MacConkey Agar Powder?

MacConkey Agar Powder is a dehydrated microbiological medium used to prepare a selective growth environment for Gram-negative bacteria. It contains bile salts and crystal violet to inhibit Gram-positive bacteria, while lactose and neutral red allow easy differentiation of lactose-fermenting organisms.

Why Use This Medium?

This product is essential for laboratories to test water, food, clinical, and environmental samples. It helps identify bacteria such as E. coli, Salmonella, and Shigella. When prepared, lactose fermenters form pink or red colonies, while non-fermenters remain colorless, providing clear, reliable results.
