Gram-positive, coccoid- or ovoid-shaped cells, 0.7-0.8 x 0.9-1.1 µm. Non-motile.
Colonies on MRS agar plates after 2 days of incubation at 28 ºC under aerobic
conditions are 0.1-0.2 mm in diameter, cream-coloured, circular, convex. Grows at
10-37 ºC (optimum, 28-30 ºC), but does not grow at 4 or 40 ºC. Grows at pH 6.5-9.0
(optimum, pH 7.0-8.0). Facultatively anaerobic.
