R2A Agar

Traditionally, standard methods for enumeration of heterotrophic bacteria in water have used nutritionally rich media with incubation at 35°C. This may represent only a small percentage of bacteria present in the sample. R2A agar is a nutritionally reduced medium which, when combined with incubation at lower temperatures for longer time periods, results in enhanced recovery of stressed and chlorine damaged organisms from treated waters resulting in higher more realistic bacterial counts.
