Gram-positive cocci, 1-1.5 μm in diameter. Endospores are not formed. Nonmotile.
Colonies are pale cream or pale orange, circular, smooth and opaque after incubation
on Marine Agar for 2 days at 30 ºC. Optimal growth occurs at 30-37 ºC, at pH 5-6 and
with 0-4 % NaCl, over 1-2 days on MA or in MB. Aerobic.
