Oxoid™ TBX Agar (5kg) is a selective medium used for the enumeration and isolation of Escherichia coli and Coliforms in water, food, and environmental samples. The medium contains a chromogenic substrate that allows the differentiation of E. coli based on the characteristic formation of blue colonies, while also supporting the growth of coliforms.

Key Features:

• Form: Dehydrated powder
• Weight: 5kg
• Application: Isolation and enumeration of E. coli and coliforms from water, food, and environmental samples
• Composition: Contains chromogenic substrates for the differentiation of E. coli (blue colonies), as well as nutrients that support the growth of coliforms and inhibit the growth of non-target organisms
• Preparation: Suspend 95g in 1 litre of distilled water, mix thoroughly, and autoclave at 121°C for 15 minutes
• Yield: Approximately 52.5 litres of prepared medium
• Storage: Store the dehydrated medium at 10–30°C, protected from moisture and light
• Compliance: Suitable for use in microbiological testing protocols for the detection and enumeration of E. coli and coliforms
