Gram-negative, motile, slightly curved rods, 0.6-0.9 µm in diameter, singly and in
pairs. Sporulate only on Bacillus fumarioli agar at pH 7 after 2 days: central /
paracentral / subterminal, ellipsoidal endospores in unswollen / slightly swollen
sporangia.

Colonies are raised, dark- cream, up to 4 mm in diameter, with entire edges and have
loose biomass and egg-shell textured surfaces on TSA after 3 days. Facultatively
anaerobic. Growth temperature 30-45 ºC (optimum 30 ºC); pH 4-7.5. NaCl, alantoin or
urate are not required for growth.
