Gram-positive cocci, 0.7-1 μm in diameter. Nonmotile. Endospores are not formed.
Colonies on LB agar plates after 3 days cultivation are yellow, smooth, circular and
0.5-1.5 mm in diameter. Optimal growth occurs at 30.5-31.5 ºC and pH 6–6.2.5. No
growth at 4 or 45 ºC. No growth in 7% NaCl. Aerobic.
