R2A Agar Medium (EP) for Total Bacteria Counting in Drinking Water
R2A Agar Medium is an essential tool for microbiologists and water quality testing labs, designed specifically to count the total number of bacteria in drinking water. This high-quality medium meets European Pharmacopoeia (EP) standards, ensuring reliable results for environmental monitoring and public health assessments.
Key Features and Benefits
This premium agar medium contains a carefully balanced formula that promotes the growth of a wide range of bacteria. The key components include:
- Proteose Peptone (0.5 g/L): Provides essential nutrients for bacterial growth.
- Acid Hydrolyzed Casein (0.5 g/L): Supplies amino acids and peptides.
- Yeast Extract Powder (0.5 g/L): Enriches the medium with vitamins and growth factors.
- Soluble Starch (0.5 g/L): Acts as a carbon source for energy.
- Dipotassium Phosphate (0.3 g/L): Buffers the medium to maintain pH stability.
- Magnesium Sulfate (0.024 g/L): Essential for enzyme activity.
- Sodium Pyruvate (0.3 g/L): Supports cellular metabolism.
- Agar (15.0 g/L): Provides a solid matrix for bacterial colonies.
- Glucose (0.5 g/L): Enhances growth of fastidious organisms.
Preparation Instructions
To prepare the R2A Agar Medium, suspend 15.12 g of the medium in 1 liter of deionized or distilled water. Dispense the solution into triangular flasks and sterilize it in an autoclave at 121°C (15 lbs.) for 15 minutes. This straightforward preparation method ensures optimal conditions for accurate total bacteria counts in drinking water.
Optimal Growth Conditions
The ideal pH range for R2A Agar Medium is between 7.0 and 7.4 at 25°C. This pH balance supports a diverse microbial population, making it perfect for detecting bacteria in various water sources. By using R2A Agar, laboratories can ensure compliance with safety standards, providing confidence in their drinking water analyses.
