Description
- R2A Agar was developed for bacteriological plate counts of treated potable water
- A low nutrient medium, such as R2A Agar, in combination with a lower incubation temperature and longer incubation time stimulates the growth of stressed and chlorine-tolerant bacteria
- Nutritionally-rich media, such as Plate Count Agar, support the growth of fast-growing bacteria but may suppress slow growing or stressed bacteria found in treated water
- When compared with nutritionally rich media, R2A Agar has been reported to improve the recovery of stressed and chlorine-tolerant bacteria from drinking water systems
- Recommended in standard methods for pour plate, spread plate and membrane filter methods for heterotrophic plate counts
- Intended for use only with compromised bacteria found in treated potable water
- Yeast extract provides a source of trace elements and vitamins
- Peptone and casamino acids provide nitrogen, vitamins, amino acids, carbon and minerals
- Dextrose serves as a carbon source
- Soluble starch aids in the recovery of injured organisms by absorbing toxic metabolic by-products
- Sodium pyruvate increases the recovery of stressed cells
- Potassium phosphate is used to balance the pH and provide phosphate
- Magnesium sulfate is a source of divalent cations and sulfate
- Agar is the solidifying agent
- Order Info Prices are for units of one each unless otherwise specified
- Certifications COMPF, EPA, SMWW
