Gram-positive rods, 0.8 / 0.56 µm. Non-motile. Non-spore-forming.
Colonies on horse 6% blood agar are white, convex, smooth, shiny, translucent, up to
2 mm in diameter after 3-5 days of aerobic incubation at 37 ºC. Grows aerobically or
in 80% nitrogen-10% hydrogen-10% CO2 atmosphere. Liquid media: CO2 stimulates
growth.
