Abstract

An aerobic, Gram-stain-negative, motile, mesophilic bacterium, designated strain 7515T-07, was isolated from an air sample in the Taean region, Republic of Korea. The strain grew at 4–40 °C (optimum, 30 °C) and pH 5.0–9.0 (optimum, pH 7.0). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain 7515T-07 was related to members of the genus and had highest 16S rRNA gene sequence similarity with 170/96 (96.7 %). 16S RNA gene sequence similarity between strain 7515T-07 and ATCC 49956 (the type species of the genus ) was 93.4 %. Strain 7515T-07 contained Q-10 as the ubiquinone and Cω7 and C cyclo ω8 as the dominant fatty acids (>10 %). The polar lipid profile contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine and two unidentified aminolipids. The DNA G+C content was 73.0 mol%. Combined data from phenotypic, phylogenetic and chemotaxonomic studies demonstrated that strain 7515T-07 is a representative of a novel species of the genus , for which the name sp. nov. is proposed. The type strain is 7515T-07 ( = KACC 16529 = NBRC 108923).
