Mycobacterium, Mycobacterium aromaticivorans Hennessee et al. 2009.
Cells are pleomorphic, with coccoid and long rod shapes. Weak Gram-positive.
Does not form single colonies on any media tested, only growing on solid media at
dilutions turbid enough to support a lawn of growth. Mucoid and yellow-pigmented in
light or dark. Grows at 28 and 37 ºC. Can grow in media containing 5% NaCl. Fast
Isolated from polycyclic aromatic hydrocarbon-contaminated soil of a former oil-gasification company site in Hilo, Hawaii, USA.
Can degrade/utilize phenanthrene and fluorene, but not pyrene, benzo[a]pyrene or fluoranthene.

and Mycobacterium aromaticivorans sp. nov. Int J Syst Evol Microbiol 2009; 59:378-387.
Positive results for catalase, alkaline phosphatase and alpha-glucosidase.
Can utilize glucose, D-fructose, D-mannitol, D-mannose, trehalose, and succinic acid.
Negative results for beta-glucuronidase, beta-galactosidase, N-acetyl-beta-glucosaminidase, gelatin hydrolysis, nitrate reduction,
pyrrolidonyl arylamidase, esculin hydrolysis and urease.
No utilization of L-arabinose, citrate, dextrin, glycerol, D-ribose, and D-xylose.
