R2A AGAR ACC. EP

R2A Agar (Reasoner´s 2A agar) is designed to promote the growth of micro-organisms that grow in low nutrient environments, such as water. The reduced amount of nutrients in the medium allows the growth of aerobic, heterotrophic micro-organisms, which are adapted to low nutrient content. The low concentration of yeast extract, casein hydrolysate, peptone, and glucose allows the growth of a wide spectrum of micro-organisms, without the fast-growing micro-organisms suppressing the slow-growing species (which would be the case on richly nutritious media). Starch and pyruvate particularly support the growth of injured the micro-organisms.
