title: Fabibacter pacificus sp. nov., a moderately halophilic bacterium isolated from seawater.
abstract: A Gram-stain-negative, aerobic, moderately halophilic bacterium, strain DY53(T), 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 DY53(T) 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 UST030701-097(T) was the closest neighbour, with 96.7 % sequence similarity. Based on phylogenetic, chemotaxonomic and phenotypic data, we propose that strain DY53(T) represents a novel species of the genus Fabibacter, for which the name Fabibacter pacificus sp. nov. is proposed. The type strain is DY53(T)( = CGMCC 1.12402(T) = JCM 18885(T)).
