''Mycobacterium pyrenivorans'' is a scotochromogenic, rapidly growing mycobacterium, first isolated from an enrichment culture obtained from soil that was highly contaminated with polycyclic aromatic hydrocarbons (PAHs). The soil sample was collected on the site of a former coking plant at Ubach-Palenberg, Germany. Etymology: pyrenivorans; digesting pyrene. ==Description== Microscopy *Gram-positive, acid-fast rods. Colony characteristics *The rough colonies show a scotochromogenic yellow colour, which intensifies after exposure to light. Physiology *A rapidly growing mycobacterium, growth appears within 7 days at 35 C *Cells grow well between 24 and 37C but not at 42C. \ *In liquid media, the cells clump together or show biofilm formation on glass. *Catalase-positive. Nitrate reduction test shows a weak reaction. *Does not hydrolyse Tween 80 within 10 days. *Mineralizes phenanthrene, fluoranthene, and pyrene, but not anthracene or benzo()pyrene. Differential characteristics *The mycolic acid HPLC elution profile is unique and can be used for differentiation from the closely related species M. aurum, M. austroafricanum, M. vaccae and M. vanbaalenii and all other mycobacteria. 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 pyrenivorans」の詳細全文を読む スポンサード リンク
