Acid-fast rods, 0.4-0.5 x 1.0-1.2 µm. Gram-positive. Non-motile. Non-spore-forming.
Colonies are circular, convex, entire, light-yellow in colour and 0.1-0.5 mm in diameter
on R2A agar after 3 days of incubation at 25 ºC. Grows at 10-37 ºC (optimum 25 ºC),
pH 4.0-9.0 (optimum pH 7.0) and with 0-5 % (w/v) NaCl (optimum 2 % (w/v) NaCl).
Growth also occurs on Nutrient agar, Luria-Bertani agar, Tryptic soy agar, ISP2, ISP4,
PDA, Bennet’s agar, Mueller-Hinton agar and Middlebrook 7H10.
