Abstract

A novel bacterium, designated F081-2, isolated from seawater from Damupo beach in Pohang, Korea, was investigated using a polyphasic taxonomic approach. Cells were yellow-pigmented, strictly aerobic, motile by gliding, Gram-negative-staining and rod-shaped. The temperature, pH and NaCl ranges for growth were 4–35 °C, pH 5.5–9.5 and 1.0–5.0 %, respectively. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain F081-2 belonged to a distinct lineage in the genus of the family sharing 93.7–98.1 % similarity with recognized members of the genus. Low levels of DNA–DNA relatedness values were found between strain F081-2 and KCTC 12219 (61.1 %), KCTC 12221 (47.0 %), KCTC 22026 (39.3 %), CCUG 56098 (34.3 %) and JCM 17633 (33.4 %). The major cellular fatty acids were iso-C (25.3 %), iso-C G (14.6 %), iso-C 3-OH (9.3 %), anteiso-C (7.8 %) and iso-C 3-OH (7.6 %). The polar lipid profile was composed of phosphatidylethanolamine, one unidentified aminolipid, one unidentified phospholipid, one unidentified aminophospholipid and six unidentified lipids. The major respiratory quinone was menaquinone-6 and the DNA G+C content of the strain was 32.3 mol%. On the basis of phenotypic, phylogenetic and genotypic data, strain F081-2 represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is F081-2 ( = KCTC 23552 = JCM 17633).
