Description
FB2 Enrichment Broth for Listeria Detection
FB2 Enrichment Broth is specifically designed for the enrichment of Listeria species in laboratory testing. Each pack contains 20 tubes of 10ml, and each tube is individually wrapped in sterile plastic to prevent leakage and contamination. Therefore, it is ideal for use in both food safety and clinical testing.
The broth’s carefully crafted formula promotes the growth of Listeria, while simultaneously inhibiting most Gram-negative and Gram-positive bacteria. It contains peptones, yeast extract, and beef extract, which provide essential nutrients such as nitrogen, vitamins, and amino acids. In addition, lithium chloride and other antibiotics suppress the growth of competing organisms. As a result, this medium ensures selective Listeria enrichment.
Quality Control Testing
FB2 Enrichment Broth has undergone thorough testing with various quality control strains to ensure its reliability and effectiveness. These tests confirm the medium’s ability to promote Listeria growth while limiting other bacteria:
| Strain | Strain Number | Inoculum (CFU) | Result |
|---|---|---|---|
| Listeria monocytogenes | BB ATCC19115 + BB ATCC25922 + BB ATCC29212 | – | >100 CFU on PALCAM; black-centered colonies, gray-green zones |
| Escherichia coli | BB ATCC25922 | 1000–5000 | >100 CFU on TSA |
| Staphylococcus aureus | BB ATCC29212 | 1000–5000 | <100 CFU on TSA |
Consequently, the broth ensures selective Listeria enrichment while effectively limiting unwanted bacteria like E. coli and S. aureus. This results in more accurate and reliable detection.
Key Features
- Selective Growth: FB2 Enrichment Broth effectively supports Listeria growth, while preventing competing bacterial growth.
- Nutrient-Rich Formula: The broth includes essential nutrients, such as nitrogen, vitamins, and amino acids, which are crucial for bacterial growth.
- Buffer System: The inclusion of sodium phosphates maintains pH stability, ensuring consistent and repeatable results.
- Accurate Results: Extensive quality control testing confirms the broth’s reliability in Listeria detection.
Applications
- Food Safety Testing: Essential for identifying Listeria monocytogenes in food products, including meat, dairy, and ready-to-eat items.
- Environmental Testing: Ideal for monitoring contamination in food processing environments, particularly in areas prone to Listeria outbreaks.
- Clinical Microbiology: Reliable for detecting Listeria in clinical samples, especially from high-risk patients.
Given these advantages, FB2 Enrichment Broth is an indispensable tool for laboratories focused on Listeria detection. Its selective growth formula and high standards in quality control make it highly effective in producing consistent and accurate results. visit our [Ready-to-use culture medium] for more related products
