Description of Sulfitobacter sediminilitoris sp. nov., isolated from a tidal flat

A Gram-stain-negative bacterial strain, JBTF-M27^T, was isolated from a tidal flat from Yellow Sea, Republic of Korea. Neighbor-joining phylogenetic tree of 16S rRNA gene sequences showed that strain JBTF-M27^T fell within the clade comprising the type strains of Sulfitobacter species. Strain JBTF-M27^T exhibited the highest 16S rRNA gene sequence similarity (98.8%) to the type strain of S. porphyrae. Genomic ANI and dDDH values of strain JBTF-M27^T between the type strains of Sulfitobacter species were less than 76.1 and 19.2%, respectively. Mean DNA-DNA relatedness value between strain JBTF-M27^T and the type strain of S. porphyrae was 21%. DNA G + C content of strain JBTF-M27^T from genome sequence was 57.8% (genomic analysis). Strain JBTF-M27^T contained Q-10 as the predominant ubiquinone and C_18:1ω7c as the major fatty acid. The major polar lipids of strain JBTF-M27^T were phosphatidylcholine, phosphatidylglycerol and one unidentified aminolipid. Distinguished phenotypic properties, along with the phylogenetic and genetic distinctiveness, revealed that strain JBTF-M27^T is separated from recognized Sulfitobacter species. On the basis of the data presented, strain JBTF-M27^T (= KACC 21648^T = NBRC 114356^T) is considered to represent a novel species of the genus Sulfitobacter, for which the name Sulfitobacter sediminilitoris sp. nov. is proposed.
