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