MacConkey Agar, Granulated

MacConkey Agar is a widely used medium in microbiology to identify and isolate Gram-negative bacteria. This selective and differential medium contains bile salts and crystal violet, which effectively inhibit the growth of Gram-positive bacteria, ensuring the focus remains on Gram-negative microorganisms. Additionally, MacConkey agar includes lactose and neutral red to differentiate lactose-fermenting and non-lactose-fermenting Gram-negative bacteria. When microorganisms are placed on MacConkey agar and incubated at the appropriate temperature, they form visible colonies that can be easily identified. Lactose-fermenting bacteria produce acid on MacConkey agar, turning their colonies pink or red, while non-lactose-fermenting bacteria remain colorless.

MacConkey agar is a go-to medium for isolating and identifying pathogenic or potentially pathogenic Gram-negative bacteria in clinical, food, and pharmaceutical industries.
