Gram-positive, long rods (0.7-0.8 x 5.5-6.5 µm). Motile. Produce spores.
Colonies are smooth, transparent, circular, and light ivory in color and 3-4 mm in
diameter after 3 days of incubation on marine agar at 25 ºC. Growth also occurs on
nutrient agar and TSA, but not on MacConkey agar. Growth occurs at 20-37 ºC
(optimum 25 ºC), at pH 6-10 (optimum pH 6) and in 0-8% (w/v) NaCl. Aerobic.
