It is a chemoorganotrophic, halophilic bacterium first isolated from a solar salt facility located in Bonaire, Netherlands Antilles.

[1] Halomonas elongata cells are gram-negative rods which are motile by either polar or peritrichous flagella.

[1] On a solid medium, H. elongata produce glistening, opaque white colonies that are about 2 mm in diameter.

[1] Cells of H. elongata are capable of utilizing malonate, fermenting glucose, and oxidizing glycerol, sucrose, mannose and cellobiose.

[1] All strains are susceptible to HgCl2 and chloromycetin but have only a slight susceptibility to other antibiotics like penicillin, streptomycin, tetracycline, ampicillin, vibriostat O/129, novobiocin, neomycin, bacitracin and nalidixic acid.
