R2A Agar 500g

Brand:

Thermo ScientificTM OxoidTM

Enumerate heterotrophic bacteria from drinking water samples with Thermo Scientific™ Oxoid™ R2A Agar (Dehydrated). This nutritionally reduced medium was specially designed to enhance the recovery of stressed and chlorine damaged bacteria from treated water samples. Stressed or injured organisms during water treatment are unable to grow on high nutrient media since faster-growing organisms outgrow the former. Therefore the use of a low nutrient medium like R2A Agar incubated for longer incubation periods allows these stressed organisms to grow well.
