Thermo Scientific™ Oxoid™ MRS (ISO) Agar is a dehydrated microbiological culture medium specifically formulated for the selective isolation and enumeration of mesophilic lactic acid bacteria (LAB) from food and dairy products in accordance with ISO 15214:1998 standards. Developed by De Man, Rogosa, and Sharpe, this medium supports the growth of a wide range of Lactobacillus species, including slow-growing and nutritionally demanding strains such as Lactobacillus brevis and Lactobacillus fermenti, while providing optimal conditions for reliable colony development and enumeration.
MRS (ISO) Agar is widely used in food microbiology laboratories, quality control environments, and research institutions to monitor microbial populations in fermented foods, dairy products, and probiotic formulations. Its optimized formulation enhances selectivity and supports robust growth of lactic acid bacteria genera including Lactobacillus, Streptococcus, Pediococcus, and Leuconostoc. The medium offers superior consistency compared to older tomato juice-based formulations, ensuring reproducible and standardized microbiological results.
Applications
- Isolation and enumeration of lactic acid bacteria in food products
- Microbiological testing of dairy products and fermented foods
- Quality control testing in food manufacturing and processing facilities
- Probiotic research and development
- Fermentation studies and industrial microbiology
- Academic and research laboratory microbiology applications
Key Features
- Compliant with ISO 15214:1998 for enumeration of mesophilic lactic acid bacteria
- Supports growth of fastidious and slow-growing Lactobacillus species
- Provides selective conditions favoring lactic acid bacteria growth
- Superior performance compared to traditional tomato juice-based media
- Consistent and reproducible colony formation for reliable enumeration
- Suitable for food safety, probiotic, and fermentation microbiology testing
