Gram-positive rods, 0.8-1 / 1-2 µm, occurring in pairs. Non-spore-forming. Non-motile.
Colonies are beige, convex, smooth with entire margins, 0.5 mm in diameter after 2
days at 30 ºC on mMRS agar. Facultative anaerobe. Grows at temperature range
10-32 ºC (optimally at 30 ºC). Can grow at pH 5.0-10.0. Weak growth in 5.0% NaCl,
and negative in 6.0% NaCl media.
