Gram-positive spherical or ovoid cells, 0.5-1 μm in diameter, grouped in chains or
pairs. Nonmotile, nonspore-forming.
pairs. Nonmotile, nonspore-forming.
Colonies on GYP agar plates are circular, raised or low-convex with entire margins,
and nonpigmented. Small, red colonies appear on Slanetz–Bartley agar. No growth is
observed on kanamycin aesculin azide agar. Weak blood haemolysis.
Facultatively anaerobic. Grows at pH 5.0–9.6, at 15–45 ºC and in 2–6% NaCl. No
growth occurs at 10 ºC and in broth containing 6.5% NaCl. Riboflavin, niacin and
calcium pantothenate are required for growth.
