Gram-positive irregular rods, 0.5 / 1.5-8 µm long, singly or sometimes arranged in ‘V’
shape. Non-motile. Non-spore-forming.
shape. Non-motile. Non-spore-forming.
Colonies are convex, with entire margins, white, and 1.5-2 mm in diameter after 24 h
anaerobic incubation at 37 ºC on TPYG agar. Aggregated cell clumps are formed in
liquid cultures (TPYG liquid) but cells are readily dispersed by shaking. Growth
temperature 25-49.5 ºC, optimum 37-41 ºC. Optimum pH 7.0-7.2. Can grow at pH 4.5
and weak growth at pH 4.0. Strictly anaerobic.
