Oxoid™ MacConkey Agar 2.5kg Each

Oxoid™ MacConkey Agar is a selective and differential culture medium designed for the isolation and differentiation of Gram-negative enteric bacteria based on lactose fermentation. It is widely used in clinical, food, and environmental microbiology to detect and enumerate coliform organisms.

Supplied in a 2.5kg dehydrated powder format, this medium provides reliable performance and is suitable for high-throughput laboratory applications. The formulation includes bile salts and crystal violet to inhibit Gram-positive organisms, while lactose and neutral red enable differentiation of lactose fermenters, which produce pink colonies, from non-fermenters, which remain colorless.
