R2A Fluid Medium for Water Microbiology – Low-Nutrient Bacterial Culture Medium

R2A Fluid Medium is a specialized bacterial culture medium designed for the isolation and cultivation of low-nutrient-dependent bacteria in water samples. This ready-to-use formulation is ideal for environmental microbiology, water quality testing, and microbial analysis in research and industrial settings.

Key Features:

• Scientifically Formulated: Contains 0.5g/L yeast extract, 0.25g/L tryptone, 0.5g/L casamino acids, 0.25g/L peptone, 0.5g/L starch, 0.5g/L dextrose, 0.3g/L dipotassium phosphate, 0.3g/L sodium pyruvate, and 0.1g/L magnesium sulfate to support slow-growing bacterial species.

• pH Stability: Maintains a stable pH of 7.2±0.2 at 25°C for consistent performance in water sample analysis.

• Low-Nutrient Composition: Mimics natural aquatic environments for accurate detection of fastidious and oligotrophic bacteria.

• Easy Preparation: Dissolve 3.2g of the powder in 1L distilled or deionized water, mix until dissolved, sterilize at 121°C for 15 minutes, and store at room temperature.

• Long Shelf Life: 3-year stability under proper storage conditions (cool, dry, and protected from light).

Applications:

• Water Microbiology: Ideal for detecting and cultivating bacteria in drinking water, surface water, and wastewater.

• Environmental Testing: Supports microbial analysis in ecological and environmental studies.

• Microbial Enumeration: Enables reliable quantification of low-abundance bacterial populations.
