A pink-coloured bacterial strain, designated 5715S-9, was isolated from an air sample collected in Suwon, Republic of Korea. The cells were strictly aerobic, Gram-negative, non-spore-forming, non-flagellated and short-rod-shaped. On the basis of 16S rRNA gene sequence analysis, the organism was a member of the genus , showing the highest sequence similarities with MSL-20 (96.2 % sequence similarity) and DSM 16684 (93.9 %). The major polar lipids were phosphatidylglycerol, phosphatidylcholine, diphosphatidylglycerol, phosphatidylethanolamine and an unidentified glycolipid. The major fatty acids (>10 %) were C 7, C and 11-methyl C 7. The G+C content of the DNA was 69 mol%. On the basis of both phylogenetic and phenotypic evidence, strain 5715S-9 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is 5715S-9 (=KACC 12504=DSM 19297).
