Oxoid™ Chromogenic Coliform Agar (ISO) (500g) is a selective and differential medium used for the detection and enumeration of coliforms and Escherichia coli in food, water, and environmental samples. This medium is formulated according to ISO 9308-1 standards, offering a reliable, rapid method for identifying coliform bacteria based on characteristic colony colouration. The chromogenic substrates in the medium allow for the differentiation of coliforms and E. coli by the distinct colour of their colonies.

Key Features:

• Form: Dehydrated powder
• Weight: 500g
• Application: Detection and enumeration of coliforms and Escherichia coli in food, water, and environmental samples, in accordance with ISO 9308-1 standards
• Composition: Contains chromogenic substrates and selective agents to promote the growth of coliforms and E. coli, allowing differentiation by colony colour
• Preparation: Suspend 43g in 1 litre of distilled water, mix thoroughly, and autoclave at 121°C for 15 minutes
• Yield: Approximately 11.6 litres of prepared medium
• Storage: Store the dehydrated medium at 10–30°C, protected from moisture and light
• Compliance: Complies with ISO 9308-1 for the detection and enumeration of coliforms and E. coli in microbiological testing protocols
