Gray-white, opaque, convex, low, with raised centres, somewhat glistening, and
butyrous; S-type colonies, 5-6 mm in diameter after 5 days incubation at 37 ºC on P
agar. Hemolytic on sheep blood agar. Facultatively anaerobic, growth temperature
35-37 ºC. No growth at 10 or 45 ºC. Grow in 10% NaCl medium but not in 15% NaCl.
Other growth media: Trypticase Soy Agar ± 5% sheep blood, Trypticase Soy Broth.
