Description is based on a single isolate.
Gram-positive diphtheroids cells, dumbbell-shaped (when examined after 18 hours
growth), showing typical coryneform morphology (when examined after 1 week of
growth). Non-spore-forming. Non-motile. Tuberculostearic acid and mycolic acids are
Colonies are light-grey on sheep blood Columbia agar, BHI agar and TSA.
Facultatively anaerobic growth.
Isolated from a cosmetic dry.
