R-2A Agar Himedia M962-500gm
Pack Size: 500GM
Application :
R-2A Agar is a specific type of agar medium used in microbiology for the cultivation and enumeration of heterotrophic bacteria from environmental samples.
HiMedia Laboratories is a company that produces a variety of microbiological culture media, including R-2A Agar.
R-2A Agar is designed for the cultivation of bacteria that are commonly found in natural waters, such as oligotrophic bacteria.
The exact composition of R-2A Agar may vary slightly depending on the manufacturer, but in general, it contains nutrients at reduced concentrations compared to standard media. This encourages the growth of bacteria that may be present in low numbers in environmental samples.
R-2A Agar is often considered a low-nutrient agar, and its formulation aims to mimic the conditions of oligotrophic environments.
It may contain peptone, yeast extract, agar, and other components.
This medium is frequently used for the isolation and enumeration of bacteria from water sources, including tap water, river water, and other environmental samples.
It helps researchers study the microbial diversity in these environments.

R-2A Agar, produced by HiMedia Laboratories, is a type of agar medium commonly used in microbiology for the cultivation and enumeration of heterotrophic microorganisms in water and wastewater samples. Here are 10 key points related to R-2A Agar:
Composition: R-2A Agar is formulated with a nutrient-rich base that supports the growth of a wide range of heterotrophic bacteria. The exact composition may vary, but it typically includes peptone, casein hydrolysate, yeast extract, and other nutrients.
Neutral pH: The pH of R-2A Agar is maintained near neutrality, promoting the cultivation of a diverse group of bacteria, including those that may be sensitive to acidic conditions.
Low Nutrient Levels: R-2A Agar is designed to have lower nutrient levels compared to some other media, allowing for the recovery of bacteria that may be stressed or in a viable but nonculturable state.
Heterotrophic Plate Count (HPC): This medium is often used for Heterotrophic Plate Count, a method used to estimate the total number of viable heterotrophic bacteria in a water sample.
Water Quality Testing: R-2A Agar is commonly employed in environmental microbiology for assessing the microbial quality of water and wastewater, particularly in studies related to environmental monitoring and water treatment.
Recovery of Environmental Strains: The lower nutrient levels in R-2A Agar make it suitable for the recovery of bacteria from natural environments, where some organisms may be adapted to low-nutrient conditions.
Surface Colonization: R-2A Agar is known for promoting the surface colonization of bacteria, allowing for the detection of organisms that may not be efficiently recovered on other media.
Incubation Conditions: Incubation is typically done at a moderate temperature (around 25-30°C) for a longer duration compared to other media, allowing for the recovery of slowly growing or stressed bacteria.
Colony Morphology: Different bacteria exhibit diverse colony morphologies on R-2A Agar, aiding in the differentiation and identification of bacterial species.
Quality Control: Like any laboratory medium, R-2A Agar undergoes quality control measures to ensure consistency and reliability in performance, meeting the requirements of microbiological testing standards.
Researchers and microbiologists use R-2A Agar as part of their toolkit for studying microbial populations in various environmental samples. It's important to follow proper laboratory protocols and quality control measures when using this medium.
