R2A agar (Reasoner´s 2A agar) is a culture medium developed to study bacteria which normally inhabit potable water. These bacteria tend to be slow-growing species and would quickly be suppressed by faster-growing species on a richer culture medium. Since its development in 1979, it has been found to allow the culturing of many other bacteria that will not readily grow on fuller, complex organic media. ==Typical Composition (g/l)== Proteose peptone, 0.5 Casamino acids, 0.5 Yeast extract, 0.5 Dextrose, 0.5 Soluble starch, 0.5 Dipotassium phosphate, 0.3 Magnesium sulfate per 7H2O, 0.05 Sodium pyruvate, 0.3 Agar, 15 Final pH 7 ± 0.2 @ 25 °C 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「R2a agar」の詳細全文を読む スポンサード リンク
