Gram-positive rods, 0.5-0.6 x 1.3-1.8 µm. Non-motile (cells do not possess
flagella).Produce spherical, central endospores in swollen sporangia.
flagella).Produce spherical, central endospores in swollen sporangia.
Colonies are creamy, smooth and circular to slightly irregular. Grows between 15-50
ºC (optimum 35-40 ºC) and at pH 5.0 to 8.0 (optimum pH 7.5) in marine broth. Grows
in 0-10% (w/v) NaCl. Optimal growth at 3-5% (w/v) NaCl. No growth occurs in the
presence of more than 12% (w/v) NaCl. Glucose, fructose, maltose, glycerol, yeast
extract and peptone support growth as the single carbon and energy source. Aerobic,
growth does not occur under anaerobic conditions on Marine Agar.
