Colonies on sheep-blood agar at 35 ºC are grey-translucent, weakly alpha-haemolytic
and about 1 mm in diameter and are unaffected by the absence or presence of 5%
CO2. Growth is observed at room temperature, 30, 35 and 45 ºC under aerobic
conditions. Growth is also observed at 35 ºC under anaerobic conditions. Does not
grow at 4 or 45 ºC. The optimal temperature for growth is between room temperature
and 30 ºC. Does not grow in the presence of 6.5% NaCl. Does not produce
extracellular polysaccharide on 5% sucrose agar.
