Gram positive cocci, 0.8-1.2 μm diameter, non-motile, non-sporing.
Colonies are circular, S-type, opaque, non-pigmented. Facultatively anaerobic, 35-37
ºC. Growth media: Trypticase Soy Yeast extract Agar ± 5% sheep blood, P agar,
Trypticase Soy Yeast extract Broth.
Subsp. schleiferi tolerates10% NaCl; growth on 15% NaCl delayed. Temperature
range for growth 20–45°C. Weakly hemolytic.
Subsp. coagulans is hemolytic; produces beta-hemolysin.
