abstract= We have made a polyphasic taxonomic study of strain 5CRT, isolated from Fuente de Piedra, Málaga, southern Spain. The strain is a moderately halophilic, Gram-negative rod, oxidase-positive and motile by a single polar flagellum. It does not produce acids from sugars and shows respiratory metabolism, using oxygen, nitrate and nitrite as terminal electron acceptors. It requires NaCl and grows best with 5–7.5 % w/v at temperatures of between 32 and 45 °C within a pH range of 6–8. Its 16S rRNA gene sequence indicates that strain 5CRT belongs to the genus Halomonas in the class Gammaproteobacteria. Its closest relatives are Halomonas alimentaria, H. nitroreducens, H. shengliensis and H. ventosae, with the type strains of which our strain showed 16S rRNA gene sequence similarity values of 96.7–97.8 %. DNA–DNA hybridization studies between strain 5CRT and H. ventosae CECT 5797T, the phylogenetically nearest type strain, showed 40 % relatedness. Its G+C content is 65.7 mol%. Its major fatty acids are C18 : 1 ω7c (31.36 %), C16 : 0 (25.55 %), C16 : 1 ω7c/iso-C15 : 0 2-OH (23.23 %), C19 : 0 cyclo ω8c (8.14 %), C12 : 0 3-OH (5.76 %) and C10 : 0 (2.22 %) and the predominant respiratory lipoquinone is ubiquinone with nine isoprene units (Q-9). The proposed name for the novel species is Halomonas fontilapidosi sp. nov., strain 5CRT (=CECT 7341T =LMG 24455T) being the type strain.,
