It is moderately halophilic, capable of growth at concentrations of 5–25 % w/v sea-salt mixture, the optimum being 7·5 % w/v. It is chemo-organotrophic and strictly aerobic, produces catalase but not oxidase, does not produce acid from any sugar and does not synthesize hydrolytic enzymes. The most notable difference between this micro-organism and other Halomonas species is that it is very fastidious in its use of a carbon source. It forms mucoid colonies due to the production of an exopolysaccharide. Its G+C content is 63·5 mol%. A comparison of 16S rRNA gene sequences confirmed its relationship to Halomonas species. The most closely related species is Halomonas halmophila with 95·8 % similarity between their 16S rRNA gene sequences. DNA–DNA hybridization with H. halmophila is 10·1 %. Its major fatty acids are 18 : 1ω7c, 16 : 0, 16 : 1ω7c/15 : 0 iso 2-OH, 12 : 0 3-OH, 12 : 0, 11-methyl 18 : 1ω7c and 10 : 0. The proposed name is Halomonas almeriensis sp. nov., with strain M8T (=CECT 7050T=LMG 22904T) as the type strain. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.63676-0
