Abstract
A Gram-negative, non-motile and rod-, oval- or coccoid-shaped bacterial strain, DSW-25T, which is phylogenetically closely related to the genera Staleya and Sulfitobacter, was isolated from seawater of the East Sea, Korea, and subjected to a polyphasic taxonomic study. Strain DSW-25T grew optimally at pH 7.0-8.0 and at 25 °C. It contained Q-10 as the predominant ubiquinone and C18:1ω7c as the major fatty acid. Major polar lipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine and an unidentified phospholipid. The DNA G + C content was 56.9 mol%. Strain DSW-25T exhibited 16S rRNA gene sequence similarity values of 98.4% to the type strain of Staleya guttiformis and of 96.6-97.6% to Sulfitobacter species. There were no distinct phenotypic, particularly chemotaxonomic, properties to differentiate Staleya guttiformis and strain DSW-25T from the genus Sulfitobacter. DNA-DNA relatedness data and differential phenotypic properties, together with the phylogenetic distinctiveness, demonstrated that strain DSW-25T differs from recognized Sulfitobacter species and Staleya guttiformis. On the basis of phenotypic, chemotaxonomic, phylogenetic and genetic data, strain DSW-25T was classified in the genus Sulfitobacter as a member of a novel species, for which the name Sulfitobacter donghicola sp. nov. is proposed. The type strain is strain DSW-25T (=KCTC 12864T =JCM 14565T). It is also proposed that Staleya guttiformis be transferred to the genus Sulfitobacter as Sulfitobacter guttiformis comb. nov.
