title: Litorivivens aequoris sp. nov., a gammaproteobacterium isolated from seawater.
abstract: A Gram-stain-negative, strictly aerobic, beige-pigmented, motile, chemoheterotrophic, rod-shaped or ovoid bacterium, designated strain KMU-37T, was isolated from seawater at Najeong Beach in the Republic of Korea. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that the novel isolate was affiliated with the genus Litorivivens, class Gammaproteobacteria, showing highest sequence similarity (97.4%) to Litorivivens lipolytica HJTF-7T. The DNA-DNA relatedness values between strains KMU-37Tand L. lipolytica HJTF-7Twere 11.5 ± 0.4%. The DNA G+C content of strain KMU-37Twas determined to be 53.8 mol%. Ubiquinone 8 (Q-8) was the sole respiratory quinone. The predominant cellular fatty acids were C17:1 ω8c and C16:1 ω7c and/or C16:1 ω6c. Strain KMU-37Thad phosphatidylethanolamine, phosphatidylglycerol and an unidentified lipid as polar lipids. From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, the strain is considered to represent a novel species of the genus Litorivivens for which the name Litorivivens aequoris sp. nov. is proposed. The type strain of L. aequoris sp. nov. is KMU-37T(= KCCM 90262T= NBRC 111904T).
