Acid-fast rods, 2-6 x 0.5 μm. Cords, spores mycelium or branching are not produced.
Nonmotile.
Nonmotile.
Colonies are dry, rough, and nonpigmented in the dark and also after exposure to
light. Grows on Ogawa egg medium or Lowenstein-Jensen medium after incubation
for 3 days at 28, 37, and 42 ºC, but not at 45 ºC. Grow on a modified Sauton agar
medium in which sodium glutamate is substituted for asparagine. Aerobic. Growth on
5% NaCl media is variable.

hydrolysis, acetamidase, benzamidase, isonicotinamidase, nicotinamidase, salicylamidase, and succinamidase.
No utilization as sole carbon source of citrate, benzoate, malonate, sucrose, D-galactose, L-arabinose, D-xylose, L-rhamnose, ethanol,
propylene glycol, 1,3-butylene glycol, 2,3-butylene glycol, and 1,4-butylene glycol.
