MacConkey Agar 500g About

• Selective:It inhibits the growth of gram-positive bacteria, allowing only gram-negative bacteria to grow.
• Differential:It differentiates lactose-fermenting bacteria from non-lactose-fermenting bacteria.
• Components:It typically contains lactose, bile salts, neutral red, and crystal violet.
• Lactose Fermentation:Lactose-fermenting bacteria produce acid, which lowers the pH, causing the neutral red indicator to turn pink or red, and the colonies appear pink or red.
• Non-Lactose Fermenters:Bacteria that do not ferment lactose do not produce acid, and the colonies remain colorless or the agar surrounding them remains a pale yellow.
• Application:Commonly used for isolating and identifying bacteria from various sources, including clinical samples and food.
