Abstract

ABSTRACT: Polyphasic taxonomic analysis was performed on a novel marine bacterium, designated as strain YJ057 T, isolated from marine sediment collected in the Republic of Korea. The strain was Gram-negative, beige-colored, facultatively anaerobic, coccoid or ovoid-shaped and nonmotile. Preliminary 16S rRNA gene sequence-based phylogenetic analysis indicated that this novel marine isolate belongs to the family Rhodobacteraceae of the class Alphaproteobacteria, and has the greatest (96.2%) sequence similarity to Paracoccus aestuariivivens GHD-30 T . Major (>10%) fatty acids of strain YJ057 T were C16:0 and C18:1 ω 7 c, G+C content in the genomic DNA of the strain was 63.6 mol% and the sole respiratory quinone was ubiquinone Q-10. It had phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine and some unidentified components (three aminolipids, a glycolipid, a phospholipid and two lipids). As per the distinct phylogenetic position and combination of phenotypic and genotypic traits, the strain is considered a novel species of the genus Paracoccus, and the name Paracoccus ravus sp. nov. is proposed. Abstract : Based on discriminative phylogenetic, phenotypic and genotypic characteristics, the novel strain YJ057 T represents a novel species of the genus Paracoccus, P. ravus sp. nov.
