Gram-positive cocci.
Colonies on MRS agar are white to light grey and translucent. Colonies on bovine
blood agar are translucent, grey and alpha-hemolytic. Grows on azide-containing
enterococcal selective agar as light- to dark-maroon colonies and cause blackening
of bile-aesculin agar.
Grows well at 10 and 37 ºC. No growth at 2, 42 & 45 ºC. Grows well in the presence of
2 to 6.5% NaCl.
