Abstract

Strain WPAGA1 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 . Strain WPAGA1 exhibited highest 16S rRNA gene sequence similarity with NBRC 100898 (98.1 %) and lower sequence similarity with IFO 15982 (94.6 %) and other members of the genus (<94.2 %). DNA–DNA relatedness studies showed that strain WPAGA1 was distinct from NBRC 100898 and NBRC 15982 (43±4 % and 32±2 % relatedness values, respectively). Strain WPAGA1 could be distinguished from all known members of the genus by a number of phenotypic features. However, the dominant fatty acids of strain WPAGA1 (iso-C, C and Cω6,9,12,15), 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 . Based on phenotypic and chemotaxonomic features and 16S rRNA gene sequences, strain WPAGA1 can be assigned to the genus as a representative of a novel species, for which the name sp. nov. is proposed; the type strain is WPAGA1 ( = CCTCC AB 2010364 = LMG 26175 = DSM 24597 = MCCC 1A06425).
