Phylum Actinobacteria, Class Actinobacteria, Order Actinomycetales, Suborder Corynebacterineae, Family Mycobacteriaceae, Genus
Mycobacterium, Mycobacterium pyrenivorans Derz et al. 2004.
Species description is based on a single isolate.
Acid-fast rods. Gram-positive.
Colonies are rough and show a yellow colour (scotochromogenic), which intensifies
after exposure to light. In liquid media, the cells clump together or show biofilm
formation on glass. On TSA, growth appears within 7 days at 35 ºC. Grows well
between 24 and 37 ºC but not at 42 ºC. No growth in 4% NaCl. Strictly aerobic.
Isolated from an enrichment culture obtained from soil that was highly contaminated with polycyclic aromatic hydrocarbons (PAHs) of
a former coking plant in Germany.

Mycobacterium kyogaense sp. nov., a scotochromogenic strain received as Mycobacterium vaccae. Int J Syst Evol Microbiol 2018;
Positive results for semi-quantitative catalase test, heat-stable catalase, nitrate reduction (weak reaction), and tellurite reduction.
Can utilize mannitol as sole carbon source.
Mineralizes phenanthrene, fluoranthene and pyrene but not anthracene or benzo[a]pyrene.
Negative results for acid phosphatase, arylsulphatase (3 and 14 days), beta-galactosidase, Tween 80 hydrolysis (10 days) and
urease. No utilization of citric acid, xylose, trehalose or sorbitol.
