Description

Enumerate heterotrophic bacteria from drinking water samples with ready-to-use Thermo Scientific™ Oxoid™ R2A Agar. This nutritionally reduced medium was specially designed to enhance the recovery of stressed and chlorine damaged bacteria from treated water samples.

Use R2A Agar for the microbiological examination of drinking water.

• Aids recovery of stressed and damaged bacteria giving more realistic colony count as compared to traditional media.
• Ready-to-use convenience of prepared media.

Standard methods for the enumeration of heterotrophic bacteria in water have traditionally used nutritionally rich media, such as Plate Count Agar, with incubation at 35°C¹. Organisms isolated under these conditions may represent only a small percentage of the bacteria present in the sample².

R2A Agar developed by Reasoner and Geldreich² is a nutritionally reduced medium. It was demonstrated that using this medium and incubating for longer at lower temperatures enhanced the recovery of stressed and chlorine damaged bacteria from treated waters resulting in higher, more realistic bacterial counts.
