Abstract

Pleomorphobacterium xiamenense CLW was compared with Oceanicella actignis PRQ-67 to examine the taxonomic relationship between the two organisms. The 16S rRNA gene sequence comparison showed that the two strains had 99.9 % sequence similarity. Phylogenetic analysis showed the two strains formed an independent tight cluster, distinctly branching from the closely related species in the family Rhodobacteraceae . Whole genomic comparison between the two strains revealed a digital DNA–DNA hybridization estimate of 88.4 % and average nucleotide identity of 98.8 %, strongly supporting that the two strains represented a single species. In addition, neither strain displayed any striking difference in biochemical characteristics, fatty acid composition, and polar lipid profile. According to priority, Pleomorphobacterium xiamenense is reclassified as a later heterotypic synonym of Oceanicella actignis based on the phylogenetic relationship, whole genomic comparison, fatty acid composition and polar lipid profile, and other phenotypic and biochemical properties.
