Abstract
Two Gram-negative, non-motile, non-spore-forming, rod-shaped organisms, strains SW-125T and SW-154T, were isolated from tidal flat sediment of the Yellow Sea in Korea, and subjected to a polyphasic taxonomic study. Strains SW-125T and SW-154T grew optimally at 30-37°C and in the presence of 2-3% (w/v) NaCl. They contained ubiquinone-8 (Q-8) as the predominant respiratory lipoquinone and iso-C15:0 as the major fatty acid. The DNA G+C contents of strains SW-125T and SW-154T were 44 mol%. Phylogenetic trees based on 16S rRNA gene sequences revealed that the two strains form deep evolutionary lineages of descent within the γ-Proteobacteria. Strains SW-125T and SW-154T exhibited 16S rRNA gene sequence similarity levels of less than 90% to members of the γ-Proteobacteria used in this analysis. Strains SW-125T and SW-154T showed a 16S rRNA gene sequence similarity level of 98.5% and a mean DNA-DNA relatedness level of 9.4%. Therefore, on the basis of phenotypic, phylogenetic and genomic data, a new genus, Kangiella gen. nov., is proposed to accommodate the novel strains, comprising two novel species, Kangiella koreensis sp. nov. (type strain, SW-125T = KCTC 12182T = DSM 16069T) and Kangiella aquimarina sp. nov. (type strain, SW-154T = KCTC 12183T = DSM 16071T).
