Species description is based on a single isolate.
Gram-positive rods, 0.5-0.7 x 0.6-1.2 µm. Motile by means of a single polar or
subpolar flagella. Produce round, central endospores in slightly swollen sporangia.
subpolar flagella. Produce round, central endospores in slightly swollen sporangia.
Colonies on Marine Agar are circular to irregular, raised, glistening, smooth, yellowish
orange and 2.0-3.0 mm in diameter after 2 days of incubation at 37ºC.
Growth occurs at 4-50ºC, but not at 55ºC (optimum 37 ºC; pH 6.0-11.0 (optimum pH 7-
8); in 0-30% (w/v) NaCl (optimum 10% NaCl). Aerobic.

Isolated from seawater collected from a sandy beach in a southern state of Malaysia.
Susceptible to gentamicin, kanamycin, chloramphenicol, colistin, bacitracin, nalidixic acid and tetracycline. Resistant to ampicillin,
penicillin G, carbenicillin, rifampicin, ciprofloxacin, vancomycin, erythromycin and sulfamethoxazole.
