Oxoid™ Half Fraser Broth Base (10kg) is a selective enrichment medium designed for the primary enrichment of Listeria monocytogenes and other Listeria species from food, environmental, and clinical samples. This larger quantity of broth base is ideal for high-throughput laboratories and large-scale microbiological testing. It supports the recovery and growth of Listeria species while inhibiting the growth of competing organisms, and is commonly used in the two-step enrichment process for Listeria detection as per ISO 11290.

Key Features:

• Form: Dehydrated powder
• Weight: 10kg
• Application: Primary enrichment of Listeria species from food, environmental, and clinical samples, in accordance with ISO 11290 standards
• Composition: Contains peptones, salts, and selective agents to promote the growth of Listeria species while suppressing other microbial growth
• Preparation: Suspend 29.5g in 1 litre of distilled water, mix thoroughly, and autoclave at 121°C for 15 minutes
• Yield: Approximately 340 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
