Description is based on a single isolate.
Gram-positive irregular and club-shaped rods, a typical coryneform morphology,
0.8-1.0 x 1.0-1.2 µm. Mycolic acids are present. Nonspore-forming. Nonmotile.
Isolated on glucose-yeast extract agar supplemented with cycloheximide and nalidixic
acid after 3 days of aerobically incubation at 30 ºC; opaque, yellow, low-convex
bacterial colony with a diameter of 1–2 mm was subcultured on sheep blood agar
plates. Haemolysis and CAMP test negative.
Isolated from activated sludge taken from a wastewater treatment plant in Yeongdeuk-gun, Republic of Korea.
