Description is based on a single isolate.
According to Nouioui et al. (2018), this species is a later heterotypic synonym of M. austroafricanum Tsukamura et al. 1983.

Acid-fast rods, 1.4 x 0.7 μm long. Gram-positive.
Colonies are smooth and scotochromogenic with a saffron yellow pigment on
Middlebrook 7H10 medium. Grows well on brain heart infusion, trypticase soy,
tryptone-yeast extract, and minimal balanced salt media. The temperature range for
growth is 24-37 ºC; at best, minimal growth is seen at 42 ºC; does not grow at 45 ºC.
Can grow on media supplemented with 5% NaCl.

Isolated from sediments in an oil-contaminated site in Redfish Bay, Texas, USA. This species has the ability to degrade chemicals
like high-molecular-weight polycyclic aromatic hydrocarbons.

Positive results for arylsulfatase (3 and 7 days), catalase, nitrate reduction, tellurite reduction, Tween 80 hydrolysis, and urease.
Pyrene, a polycyclic aromatic hydrocarbon, is degraded.
Negative results for niacin.
No utilization as sole carbon source of citrate, xylose, trehalose, and sorbitol.
