Oxoid™ Half Fraser Broth Base (500g) is a selective medium used for the primary enrichment of Listeria monocytogenes and other Listeria species from food, environmental, and clinical samples. This medium is designed to support the growth of Listeria species while inhibiting the growth of competing organisms. It is commonly used as part of the two-step enrichment process for Listeria detection and is formulated in accordance with ISO 11290 standards.

Key Features:

• Form: Dehydrated powder
• Weight: 500g
• Application: Primary enrichment of Listeria species from food, environmental, and clinical samples, as per ISO 11290 standards
• Composition: Contains peptones, salts, and selective agents that enhance the growth of Listeria species while suppressing non-target organisms
• Preparation: Suspend 29.5g in 1 litre of distilled water, mix thoroughly, and autoclave at 121°C for 15 minutes
• Yield: Approximately 17 litres of prepared medium
• Storage: Store the dehydrated medium at 10–30°C, protected from moisture and light
• Compliance: Complies with ISO 11290 for the detection of Listeria species, suitable for use in microbiological testing protocols
