Gram-positive, coccoid cells, 1 µm in diameter, usually occuring singly. Non-motile.
Non-spore-forming.
Non-spore-forming.
Colonies on mMRS agar plate are small, circular, smooth, convex, with entire
margins, greyish-white and 0.5-1.0 mm in diameter after 2 days incubation at 30 ºC.
Can grow at 37 ºC, at pH 11, and in 5% NaCl. No growth at 45 ºC, at pH 5 or in 6%
NaCl. Facultatively anaerobic.
