sp. nov., isolated from coastal seawater Free

Abstract

A Gram-stain-negative and non-motile bacterial strain that formed straight rods and reddish colonies, designated KJ035, was isolated from seawater from the East Sea, Republic of Korea. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain KJ035 belonged to the genus . The most closely related species were A2-91 (96.8 % 16S rRNA gene sequence similarity), A2-50A (96.7 %) and DCY57 (96.0 %). The major fatty acids were iso-C, anteiso-C, C 5 and summed feature 3 (comprising C 6 and/or C 7). The major isoprenoid quinone and polyamine were menaquinone 7 (MK-7) and homospermidine, respectively. The major polar lipids were phosphatidylethanolamine, three unidentified aminophospholipids, three unidentified aminolipids, one unidentified phospholipid and five unidentified polar lipids. The DNA G+C content of the genomic DNA was 61.0 mol%. The results of physiological and biochemical tests allowed the discrimination of the new isolate from its phylogenetic relatives. Strain KJ035 is thus considered to be a representative of a novel species of the genus , for which the name sp. nov. is proposed. The type strain is KJ035 (=KCTC 42854=CECT 9069).
