Gram-positive coccoid cells, 0.5-0.7 μm in diameter. Nonmotile. Endospores are not
formed.
formed.
Colonies on TSA are yellow, slimy, smooth, and circular with entire margins. The
temperature, pH, and NaCl ranges for growth are 15-37 ºC, pH 6-9, and 0-10% (w/v).
Optimal growth occurs at 28 ºC and at around pH 7.0–8.0. Aerobic.
