Gram-positive coccoid or ovoid cells. Non-motie. Endospores are not formed.
Colonies are beta-haemolytic mucoid, orange-pigmented when grown aerobically
on TSA with 5 % sheep blood or when grown anaerobically on M17 agar; cream
coloured when grown aerobically on M17 agar. Growth occurs at 6-40 ºC (not at 4 or
45 ºC), at pH 4.0-10.0 (not at pH 3.0) and at NaCl concentrations of 7% (w/v).
Facultatively anaerobic.
