Gram-positive / Gram-variable, motile, sometimes curved rods, 0.6-1.2 µm diameter,
singly and in pairs and in chains. Produce paracentral, ellipsoidal endospores in
unswollen / swollen sporangia.
Colonies are raised, cream, slightly umbonate, and have entire margins and glossy
or eggshell-textured surfaces on TSA. Facultatively anaerobic. Growth temperature
30-45 ºC (optimum 30 ºC); pH 4-9.5 (optimum pH 7-8). NaCl, alantoin or urate are not
required for growth.
Isolated from soil in the Drentse, an agricultural research area, The Netherlands.
Undetermined.
