Abstract

A halophilic, aerobic bacterium, designated PO-M2, was isolated from seashore sand, from Pohang, Korea and characterized on the basis of physiological and biochemical features. Phylogenetic analysis of 16S rRNA gene sequences revealed a clear affiliation of the novel strain with members of the genus . Sequence similarities between strain PO-M2 and the type strains of species belonging to the genus ranged from 94.3 to 95.5 %. Cells of strain PO-M2 were straight or slightly curved rods and formed light-yellow colonies on marine agar medium. The major isoprenoid quinone was ubiquinone (Q-8) and the predominant cellular fatty acids were C iso (19.3 %), C 9 iso (11.9 %), C iso (10.9 %), C 7 (10.4 %), C (9.0 %) and C 7 and/or C iso 2-OH (7.2 %). The G+C content of the DNA was 45.1 mol%. Based on physiological, biochemical and chemotaxonomic traits and comparative 16S rRNA gene sequence analysis, it is demonstrated that the isolate represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is PO-M2 (=KACC 11514=DSM 17923).
