title: Halomonas sediminicola sp. nov., a moderately halophilic bacterium isolated from a solar saltern sediment.
abstract: A Gram-stain-negative, moderately halophilic bacterium, designated strain CPS11T, was isolated from the sediment of a solar pond located in Shinan, Korea. Strain CPS11T was a strictly aerobic, motile, straight rod-shaped bacterium that grew at pH 5.0-9.0 (optimum, pH 7.0-8.0), at 10-37 °C (optimum, 28 °C) and at salinities of 1-20 % (w/v) NaCl (optimum, 10 % NaCl). Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain CPS11T belonged to the genus Halomonas, with sequence similarity of 98.5-94.3 % to existing type strains, showing highest sequence similarity to Halomonasfontilapidosi 5CRT (98.5 %), Halomonasventosae Al12T (98.5 %), Halomonascampaniensis 5AGT (98.2 %), Halomonas huangheensis BJGMM-B45T (98.0 %), Halomonas alimentaria YKJ-16T (98.0 %), Halomonas mongoliensis Z-7009T (97.8 %), Halomonas shengliensis SL014B-85T (97.5 %) and Halomonas cupida DSM 4740T (97.5 %). The predominant ubiquinone was Q-9. The major fatty acids were C19 : 0 cyclo ω8c, C16 : 1ω7c and/or iso-C15 : 0 2-OH, C16 : 0, C17 : 0 cyclo, C12 : 0 3-OH and C18 : 1ω7c. The polar lipids were phosphatidylglycerol, phosphatidylethanolamine, aminophospholipid, an unknown phospholipid and unknown lipids. The DNA G+C content of this novel isolate was 64.3 mol%. Levels of DNA-DNA relatedness between strain CPS11T and the type strains of ten other species of the genus ranged from 50 to 21 %. On the basis of the polyphasic analysis conducted in this study, strain CPS11T represents a novel species of the genus Halomonas, for which the name Halomonas sediminicola sp. nov. is proposed. The type strain is CPS11T(=KACC 18262T=NBRC 110636T).
