Acid-fast, coccoid to short rods. Gram-positive. Branching is not observed.
Colonies are smooth, cadmium yellow, and scotochromogenic after incubation for 5
days on trypticase soy broth and Middlebrook 7H10 agar. The temperature range for
growth is 15-37 ºC; optimal growth occurs at 30 ºC. No growth at 42 or 45 ºC.
No growth on MacConkey agar (without crystal violet).

Initially isolated from the site of a former gas works at Frederiksberg, Denmark. Later isolated from Alfalfa plants and tap water. One
report of isolation from farmed sea bream (Sparus aurata). One isolate from a catheter-related bloodstream infection in a child.

Can produce pale skin, dorsal fin necrosis, and a significant level of mortality (40%) in sea bream (Sparus aurata).
Reported catheter-related bloodstream infection in an immunocompromised child.
