The Thermo Scientific™ Oxoid™ Membrane Lauryl Sulphate Broth (Dehydrated) is a selective medium designed for the enumeration of coliform organisms and Escherichia coli in water samples using the membrane filtration technique. This broth replaces Teepol with sodium lauryl sulphate, providing an effective and reproducible medium for water microbiology workflows.
Key Features
- Selective for Coliforms and E. coli:
- Sodium lauryl sulphate suppresses non-coliform organisms, ensuring selective growth of target organisms.
- Membrane Filtration Compatible:
- Ideal for quantitative testing of coliforms and Escherichia coli in water and sewage samples.
- Reliable and Reproducible:
- Consistent performance for enumeration of coliforms and E. coli.
- Validated Methodology:
- Recommended as a standard medium for water testing by multiple references.
- Dehydrated Format:
- Easy to prepare, with a yield of 6.6L per 500g package.
Applications
1. Water Microbiology
- Enumeration of coliforms and E. coli in potable water, wastewater, and recreational water.
2. Environmental Monitoring
- Detection of fecal contamination in environmental samples, including industrial effluents.
3. Public Health Compliance
- Monitoring water quality for regulatory standards to ensure safety and compliance.
