Gram-positive cocci, 0.8-1 μm in diameter. Nonmotile. Endospores are not formed.
Colonies on TSA are yellow, smooth, and circular with entire margins, 1 mm in
diameter. Temperature range for growth is 4-45 ºC. Grows at pH 6-8 and in 0-15%
(w/v), NaCl. Optimal growth occurs at 28 ºC and about pH 7.0-8.0. Aerobic.
