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.
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.
Isolated from homogenates of a sea anemone collected from Neizhou Bay in the South China Sea.
Susceptible to (µg per disc) ampicillin (30 µg), carbenicillin (30 µg), chloramphenicol (30 µg), gentamicin (10 µg), kanamycin (30 µg),
nitrofurantoin (30 µg), novobiocin (30 µg), polymixin B (30 µg), rifampicin (5 µg) & streptomycin (10 µg).
Resistant to lincomycin (2 µg), nalidixic acid (20 µg), tetracycline (30 µg) & tobramycin (10 µg).
Undetermined.
