Gram-positive rods, 0.6-0.9 x 2.1-3.7 µm. Non-motile. Produce subterminal
endospores in swollen sporangia.
endospores in swollen sporangia.
Colonies are circular, mucoid, opaque and whitish-orange after incubation on TSA
medium for 2 days incubation at 30 ºC. Grows at 20-40 ºC (optimum 30-37 ºC), at pH
6-8 (optimum pH 7.0-7.5) and in the presence of 0-2% (w/v) NaCl. No growth is
observed at 45 ºC and at pH 5.5. Grows on nutrient agar, TSA and R2A. Aerobic.
