Abstract
Strain WPAGA1T was isolated from marine sediment of the west Pacific Ocean. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate belonged to the genus Flammeovirga . Strain WPAGA1T exhibited highest 16S rRNA gene sequence similarity with Flammeovirga yaeyamensis NBRC 100898T (98.1 %) and lower sequence similarity with Flammeovirga arenaria IFO 15982T (94.6 %) and other members of the genus Flammeovirga (<94.2 %). DNA–DNA relatedness studies showed that strain WPAGA1T was distinct from F. yaeyamensis NBRC 100898T and F. arenaria NBRC 15982T (43±4 % and 32±2 % relatedness values, respectively). Strain WPAGA1T could be distinguished from all known members of the genus Flammeovirga by a number of phenotypic features. However, the dominant fatty acids of strain WPAGA1T (iso-C15 : 0, C16 : 0 and C20 : 4ω6,9,12,15c), the major polyamine (cadaverine) and the G+C content of the chromosomal DNA (32.9 mol%) were consistent with those of members of the genus Flammeovirga . Based on phenotypic and chemotaxonomic features and 16S rRNA gene sequences, strain WPAGA1T can be assigned to the genus Flammeovirga as a representative of a novel species, for which the name Flammeovirga pacifica sp. nov. is proposed; the type strain is WPAGA1T ( = CCTCC AB 2010364T = LMG 26175T = DSM 24597T = MCCC 1A06425T).
