Gram-positive cocci, 0.7-1.0 µm in diameter, occuring singly, in pairs and tetrads.
Non-motile. Non-spore-forming.

Colonies are greyish white, low-convex, circular, entire, opaque and about 1 mm in
diameter after 24 hours cultivation on MRS plates at 37 ºC. Growth occurs at 15-45 ºC,
optimally at 32-34 ºC. Grows at pH range 3.5-8.3, optimally at pH 6.0-6.8. Grows in 6.5
and 7% NaCl, not in 4% NaCl. Can grow in up to 7% (v/v) ethanol. Facultatively
anaerobic.
