abstract= A novel Gram-stain-negative, rod-shaped, non-motile strain, designated GKXT, was isolated from deep seawater. Strain GKXT was able to grow at 20–35 °C (optimum, 25 °C), pH 5.5–9.5 (optimum, 7.5) and 0–4.0 % (w/v) NaCl (optimum, 1.0 %). The major fatty acids were C16 : 1ω9c (15.4 %), C16 : 0 (18.4 %), C14 : 0 (12.0 %), iso-C14 : 0 (30.1 %) and anteiso-C15 : 0 (5.7 %). Strain GKXT contained phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and an unidentified glycolipid as the main polar lipids. The only isoprenoid quinone was menaquinone-9. The diagnostic amino acids of the cell-wall peptidoglycan contained meso-diaminopimelic acid. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain GKXT belonged to the genus Luteolibacter in the family Verrucomicrobiaceae . The 16S rRNA gene sequence of this strain showed 98.0, 93.5 and 93.3 % sequence similarity, respectively, with those of Luteolibacter arcticus MC 3726T, L.uteolibacter pohnpeiensisA4T-83T and L.uteolibacter cuticulihirudinis E100T. DNA–DNA hybridization value of strain GKXT with L. arcticus MC 3726T was 33.1 %. The G+C content of the genomic DNA was 59.5 mol%. On the basis of the genotypic, phenotypic, phylogenetic and chemotaxonomic characteristics, strain GKXT was proposed to represent a novel species of the genus Luteolibacter , named Luteolibacter flavescens sp. nov. (type strain GKXT=MCCC 1K03193T=KCTC 52361T).,
