ABSTRACT
A Gram-stain-negative, yellow-pigmented, strictly aerobic, non-flagellated, motile by gliding, rod-shaped bacterium, designated strain YSD2104T, was isolated from a coastal sediment sample collected from the southeastern part of the Yellow Sea. Phylogenetic analysis based on the 16S rRNA gene sequences revealed that strain YSD2104T was closely related to three type strains, Lutimonas vermicola IMCC1616T (97.4â%), Lutimonas saemankumensis SMK-142T (96.9â%), and Lutimonas halocynthiae RSS3-C1T (96.8â%). Strain YSD2104T has a single circular chromosome of 3.54 Mbp with a DNA G+C content of 38.3âmol%. The average nucleotide identity and digital DNA-DNA hybridization values between strain YSD2104T and the three type strains (L. vermicola IMCC1616 T, L. saemankumensis SMK-142T, and L. halocynthiae RSS3-C1T) were 74.0, 86.2 and 73.6â%, and 17.9, 30.3 and 17.8â%, respectively. Growth was observed at 20-30â°C (optimum, 30â°C), at pH 6.5-8.5 (optimum, pH 7.0), and with NaCl concentrations of 1.5-3.5â% (optimum, 2.5â%). The major carotenoid was zeaxanthin, and flexirubin-type pigment was not produced. The major respiratory quinone was menaquinone-6. The major fatty acids (>10â%) were iso-C15ââ0, iso-C15ââ1 G, iso-C17ââ0 3-OH, summed feature 3 (C16ââ1 ω6c and/or C16ââ1 ω7c), and summed feature 9 (iso-C17ââ1 ω9c and/or 10-methyl C16ââ0). The major polar lipids were phosphatidylethanolamine, one unidentified aminophospholipid, two unidentified aminolipids, and eight unidentified lipids. Conclusively, based on this polyphasic approach, we classified strain YSD2104T (=KCTC 102008T=JCM 36287T) as representing a novel species of the genus Lutimonas and proposed the name Lutimonas zeaxanthinifaciens sp. nov.
