Oxoid™ Chromogenic E.Coli Medium 500g

Oxoid™ Chromogenic E. coli Medium (500g) is a selective and differential medium designed for the rapid and specific isolation and identification of Escherichia coli from clinical, environmental, and food samples. The medium contains chromogenic substrates that produce a characteristic colour change in the presence of E. coli, enabling its differentiation from other coliforms and microorganisms.

Key Features:

• Form: Dehydrated powder
• Weight: 500g
• Application: Isolation and identification of Escherichia coli from food, water, and environmental samples
• Composition: Contains nutrients to support the growth of E. coli and other coliforms, with selective agents to inhibit non-target organisms. Chromogenic substrates allow the differentiation of E. coli based on a distinct colour change (typically blue or blue-green colonies)
• Preparation: Suspend 34g in 1 litre of distilled water, mix thoroughly, and autoclave at 121°C for 15 minutes
• Yield: Approximately 14.7 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 rapid detection and enumeration of E. coli in water, food, and environmental samples
