Gram-positive rods of various shapes and branched with ‘Y’ at both sides.
Non-motile. Non-spore-forming.
Non-motile. Non-spore-forming.
Colonies are white, opaque, smooth, 1-2 mm in diameter after 3 days of anaerobic
incubation on TPY agar or MRS agar supplemented with L-cysteine hydrochloride (0.5
g/l), acetic acid (1 ml/l) and mupirocin (0,1 g/l). Grows at 22-48 ºC, optimally at 37 ºC,
at pH 4.0-7.5 (optimally at pH 7.0). Non-haemolytic. Facultatively anaerobic.
