N2 - A Gram-stain-negative, aerobic, moderately halophilic bacterium, strain DY53T, was isolated from a deep-seawater sample collected from the eastern Pacific Ocean. This isolate grew in the presence of 0.5-10.0% (w/v) NaCl, at pH 6.5-8.5 and at 15-40 °C. The optimum NaCl concentration for growth of DY53T was 2% (w/v) at 35 °C. Chemotaxonomic analysis showed MK-7 as the predominant menaquinone and iso-C15: 0, summed feature 3 (iso-C15: 0 2-OH and/ or C16: 1ω7c), iso-C15: 1 G, iso-C15: 0 3-OH and iso-C17: 0 3-OH as major cellular fatty acids. The genomic DNA G+C content was 40.8 mol%. Phylogenetic trees based on 16S rRNA gene sequences revealed that Fabibacter halotolerans UST030701-097T was the closest neighbour, with 96.7% sequence similarity. Based on phylogenetic, chemotaxonomic and phenotypic data, we propose that strain DY53T represents a novel species of the genus Fabibacter, for which the name Fabibacter pacificus sp. nov. is proposed. The type strain is DY53T(=CGMCC 1.12402T=JCM 18885T).
