Abstract

A novel bacterium, strain 7515T-26, was isolated from an air sample collected in Taean region, Republic of Korea. Cells were aerobic, Gram-stain-positive, non-flagellated cocci, growing in the temperature, pH and NaCl ranges of 10–33 °C, pH 5.0–9.0 and 0–2 % (w/v). It shared high 16S rRNA gene sequence similarity with EL-17A (97.6 %), FA2 (96.9 %) and FA1 (96.9 %), showing high sequence similarities of 96.5–97.6 % with members of the genus . Phylogenetic trees based on 16S rRNA gene sequences showed that strain 7515T-26 and members of the genus formed a compact cluster separable from other genera. The isolate contained anteiso-C, iso-C 3-OH and iso-C as the major cellular fatty acids, and MK-9(H) as the predominant isoprenoid quinone. Polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, two unknown phospholipids and one unknown lipid, and the DNA G+C content was 73.1 mol%. The peptidoglycan type was A3γ. It showed DNA–DNA hybridization values of less than 70 % with EL-17A. On the basis of the evidence from this polyphasic study, a novel species, sp. nov., is proposed. The type strain is 7515T-26 ( = KACC 17306 = DSM 27139).
