[3] Unlike its relative, H. chejuensis, H. ganghwensis is obligately halophilic, and both have distinctly different metabolic capabilities and fatty acid content.

[4] Hahella ganghwensis forms a round, smooth, and convex colony with rod-shaped cells that are motile via the propulsion of a unipolar flagellum.

[5] Hahella gaghwensis was first characterized from isolates obtained from the Ganghwen Island off of the coast of South Korea.

They determined through 16S rRNA sequencing that a strain, FR1050, was distinct enough from model H. chejuensis rRNA to warrant description as a separate species, and further research showed various biochemical and physiological differences Notable for the aerobic microbe is the ability of H. ganghwensis to produce an overabundance of extracellular polysaccharides.

[6] It is in the gamma proteobacteria, but has no known industrial or human health affects, and more research will be required in order to determine the niche that the bacterial strain occupies.
