Cells' size is 1.3-4.0 x 0.5-1.2 µm. Gram-positive but easily decolorized, motile. Spores are spherical or slightly oval, 0.8-1.3 µm in
diameter, subterminal or terminal, usually swelling the sporangium.
Maximum temperature, 30-45'C; minimum temperature, 5-15 ºC. Aerobic.
Colonies on agar not distinctive; circular or glossy; size & opacity vary on different
media
. Liquid media is turbid; slimy deposit.
Alkaline media (optimum pH 9) containing NH3 (optimum 1% NH4Cl) are required
A defined medium contains casein hydrolysate at pH 9, ammonia, thiamine, biotin
and nicotinic acid.
Isolated from soil, water, sewage and incrustations on urinals.
None.
