Gram-positive cocci, 0.6-0.7 μm in diameter. Nonmotile. Endospores are not formed.
Colonies on Luria Bertani agar are circular, entire, smooth, yellow and 0.5-1.0 mm in
diameter. Growth occurs at 20-35 ºC (optimum, 33 ºC), at pH 5.0-9.0 (optimum, pH
7.0) and in the presence of 0-2% NaCl (optimum, 1.0%). No growth at 10 or 42 ºC.
Aerobic.
