Gram-positive, coccoid to rod-shaped cells. Non-spore forming.
Colonies on TSA, are creamy-whitish to beige, non-translucent, 1-2 mm in diameter.
Good growth occurs on TSA, nutrient agar, PYE agar and blood agar. No growth on
MacConkey agar. Growth is observed at 15-36 °C, weak at 42 °C, not at 10 or 50 °C.
Grows well in a pH range of 6.5-9.5, weak at pH of 5.5, but not at pH of 4.5. Grows well
in TSB supplemented with 0-5% (w/v) NaCl, weak in the presence of 6-8% NaCl, not
at 9% NaCl and above. Aerobic. Growth under anaerobic conditions is weak.
