Mesoflavibacter sabulilitoris sp. nov., isolated from seashore sand

A Gram-stain-negative, aerobic, non-spore-forming, non-flagellated, gliding and rod-shaped bacterial strain, designated GJMS-9^T, was isolated from seashore sand collected at Geoje island in the South Sea, South Korea. Strain GJMS-9^T grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 2.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences revealed that strain GJMS-9^T clustered with the type strain of Mesoflavibacter zeaxanthinifaciens, showing the highest sequence similarity of 99.1 %. Strain GJMS-9^T exhibited 16S rRNA gene sequence similarity of 96.5 % to the type strain of Mesoflavibacter aestuarii and of less than 96.1 % to the type strains of other recognized species. Strain GJMS-9^T contained MK-6 as the only menaquinone and iso-C_15 : 1 G, iso-C_16 : 0 3-OH, iso-C_15 : 0 and iso-C_17 : 0 3-OH as the major fatty acids. The polar lipid profile of strain GJMS-9^T containing phosphatidylethanolamine, one unidentified lipid and one unidentified glycolipid as major components was similar to that of the type strain of M. zeaxanthinifaciens. The DNA G+C content of strain GJMS-9^T was 32.2 mol% and its DNA–DNA relatedness with M. zeaxanthinifaciens DSM 18436^T was 38±6.1 %. The differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain GJMS-9^T is separated from other species of the genus Mesoflavibacter. On the basis of the data presented, strain GJMS-9^T is considered to represent a novel species of the genus Mesoflavibacter, for which the name Mesoflavibacter sabulilitoris sp. nov. is proposed. The type strain is GJMS-9^T ( = KCTC 42117^T = CECT 8597^T).
