Colony characteristics *Flat, rough, and undulated yellow, nonphotochromogenic colonies Physiology *Rapid growth occurs within 5 days at 25°C, 30°C and 37°C, but not at 45°C on Löwenstein-Jensen medium and Middlebrook 7H10 agar. *Production of thermostable catalase. *Positive for β-glucosidase, nitrate reductase, penicillinase, trehalase, urease and iron uptake. *Tween 80 hydrolysis after 10 days. *No accumulation of niacin, no degradation of salicylate to catechol. *No growth on MacConkey agar without crystal violet. 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「Mycobacterium brumae」の詳細全文を読む スポンサード リンク
