Oxoid™ MacConkey Agar No.3 (500g) is a selective and differential medium used for the isolation and differentiation of Gram-negative enteric bacteria, particularly members of the Enterobacteriaceae family, from clinical, food, and environmental samples. It is especially effective for detecting Escherichia coli and other coliforms based on lactose fermentation.

Key Features:

• Form: Dehydrated powder
• Weight: 500g
• Application: Isolation and differentiation of lactose-fermenting and non-lactose-fermenting Gram-negative bacteria
• Composition: Contains bile salts and crystal violet to inhibit Gram-positive organisms; lactose and neutral red indicator allow differentiation of lactose fermenters
• Preparation: Suspend 49g in 1 liter of distilled water, mix thoroughly, and autoclave at 121°C for 15 minutes
• Yield: Approximately 10.2 liters of prepared medium
• Storage: Store the dehydrated medium at 10–30°C, protected from moisture and light
• Compliance: Suitable for microbiological testing in food, water, and clinical diagnostics for the detection of coliforms and other enteric bacteria.
