Colonies on BHI+Y for 3 days at 32 ºC are white, irregularly sized of less than 1mm
diameter. Slightly alpha-haemolytic on Columbia medium with 5% sheep blood after
4 days at 32 ºC. Grows at temperatures of 10-40 ºC and salt concentrations of up to
7.0% (w/v) NaCl. Optimal conditions are 30-34 ºC and 1.0% (w/v) NaCl. Facultatively
