- Abstract
A Gram-stain-negative, rod-shaped, and strictly aerobic bacterium designated strain G2-bT was isolated from the marine sediment around Jeju Island, South Korea. Strain G2-bT was found to be catalase- and oxidase-positive, white-pigmented, motile with polar flagellum, and to grow optimally at 25 °C, pH 7.0 in the presence of 4% (w/v) NaCl. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain G2-bT belongs to the genus Salinimonas and was closely related Salinimonas sediminis N102T (96.7% sequence similarity), Salinimonas iocasae KX18D6T (95.4%), Salinimonas lutimaris DPSR-4T (94.7%), and Salinimonas chungwhensis BH030046T (94.6%). Strain G2-bT possessed ubiquinone 8 as the sole respiratory quinone, summed feature 3 and summed feature 8 as the major fatty acids, and phosphatidylethanolamine and phosphatidylglycerol as the major polar lipids. The genome size and G + C content of the strain G2-bT were determined to be 3,765,169 bp, and 49.7%, respectively, as a complete circular genome. Based on the genomic analyses (e.g., average nucleotide identity and digital DNA–DNA hybridization), the strain G2-BT likely represents a new species in the genus Salinimonas, for which we propose to name this novel bacterium Salinimonas marina sp. nov., and the type strain is designated G2-BT (= KCTC 72817T = VTCC 910110T).
