Idiomarina homiensis sp. nov., isolated from seashore sand in Korea.
A halophilic, aerobic bacterium, designated PO-M2(T), 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 Idiomarina. Sequence similarities between strain PO-M2(T) and the type strains of species belonging to the genus Idiomarina ranged from 94.3 to 95.5 %. Cells of strain PO-M2(T) 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(15 : 0) iso (19.3 %), C(17 : 1)omega9c iso (11.9 %), C(17 : 0) iso (10.9 %), C(18 : 1)omega7c (10.4 %), C(16 : 0) (9.0 %) and C(16 : 1)omega7c and/or C(15 : 0) 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 Idiomarina, for which the name Idiomarina homiensis sp. nov. is proposed. The type strain is PO-M2(T) (=KACC 11514(T)=DSM 17923(T)).
