Gram-positive rods, 0.3-0.4 x 2.2-3.0 µm. Motile by polar flagella. Produce central
spores, slightly deforming the cell (admin note).
spores, slightly deforming the cell (admin note).
Colonies on MA are circular, shiny, smooth, translucent, pale in colour and convex with
an entire margin. Grows at 10-42 ºC (optimum 25-37 ºC), at pH 6-10 (optimum pH 9)
and tolerates up to 10% (w/v) NaCl (optimum 3-5% (w/v) NaCl). Grows aerobically.
