Gram-positive rods, 0.6-1.5 x 1.8-4.3 µm. Motile. Produce paracentral or terminal
spores in slightly swollen sporangia.
spores in slightly swollen sporangia.
Colonies on GYEA medium are cream coloured, circular and convex with entire
margins after 3 days of incubation at 30 ºC. Growth occurs at 10-45 ºC (optimum 30
ºC), at pH 4.5-10.0 (optimum, 8.0) and in 0-4% (w/v) NaCl. Strictly aerobic.
