Description is based upon a single isolate.
Gram-positive, nonmotile straight rods, 0.5-0.6 x 3.0-5.0 µm. Produce subterminal,
ellipsoidal endospores in swollen sporangia.
ellipsoidal endospores in swollen sporangia.
Colonies are pale-yellow, low convex and translucent with slightly irregular margins,
1-2 mm in diameter on marine agar in 3-5 days at 25 ºC. Slightly halophilic and
facultatively alkaliphilic. Grow at pH 6.5-10, in 0.5-10% NaCl media (optimum 2-4%)
and at 4-30 ºC (optimum 25 ºC). Aerobic; no anaerobic growth.
