Growth was observed under strict anaerobic conditions but not aerobic or microaerobic conditions created by use of the CampyPak Plus system (with 5–15 % O 2 and 5–12 % CO 2; BBL). After 4 days of anaerobic incubation at 37 °C on modified GAM agar, Wilkins–Chalgren anaerobe agar [Wilkins–Chalgren anaerobe broth (Oxoid) with 1.5 % agar] or Schaedler anaerobe agar [Schaedler anaerobe broth (Oxoid) with 1.5 % agar], colonies were punctiform, 0.1 mm in diameter, circular and beige. Strain YIT 12065 T was saccharolytic
