Oxoid™ Membrane Lactose Glucuronide Agar 500g

Oxoid™ Membrane Lactose Glucuronide Agar (500g) is a selective medium used for the detection and enumeration of Escherichia coli and coliform bacteria in water samples. This medium is designed for use with the membrane filtration technique and incorporates chromogenic substrates that enable the identification of E. coli based on the characteristic colour change, making it suitable for microbiological analysis in water quality testing.

Key Features:

• Form: Dehydrated powder
• Weight: 500g
• Application: Detection and enumeration of Escherichia coli and coliforms in water, using the membrane filtration technique
• Composition: Contains nutrients to support bacterial growth, selective agents to inhibit non-coliform organisms, and chromogenic substrates that provide a distinct colour reaction with E. coli (blue colonies)
• Preparation: Suspend 36g in 1 litre of distilled water, mix thoroughly, and autoclave at 121°C for 15 minutes
• Yield: Approximately 13.9 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 coliform bacteria in water
