Acid-fast, curved or straight rods. Gram-positive. Nonmotile. Nonspore-forming.
Colonies on Middlebrook 7H11 agar enriched with OADC are smooth, pinkish-orange,
photochromogenic after 7-10 days. Grows at 28-34 ºC (optimum at 30 ºC). No growth
at 37 ºC or on 7H11 plates without OADC. No growth on MacConkey agar without
crystal violet. Grows on media supplemented with 5% (w/v) NaCl.

Isolated from a sphagnum peat bog in northern Minnesota, USA.
Susceptible to neomycin, ampicillin and ciprofloxacin. Resistant to gentamicin, clindamycin, erythromycin, tetracycline, bacitracin,
chloramphenicol, streptomycin, penicillin and sulfisoxazol.
