Gram-positive, straight rods, 0.5-1 x 1.5-2.5 µm. Motile. Spores are oval, subterminal
or terminal, not swelling the sporangium.
or terminal, not swelling the sporangium.
Colonies are flat with lobate margins and off-white to beige. Growth occurs at 50-65
ºC and some strains, including the type strain, are capable of growth at 45 and 70 ºC.
The optimum pH values for growth are from 6 to 9. Tolerates 0.5% but not 1% NaCl.
Facultatively anaerobic.
