Abstract:
An aerobic, Gram-stain-negative, motile, mesophilic bacterium, designated strain 7515T-07(T), 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(T) was related to members of the genus Roseomonas and had highest 16S rRNA gene sequence similarity with Roseomonas ludipueritiae 170/96(T) (96.7%). 16S RNA gene sequence similarity between strain 7515T-07(T) and Roseomonas gilardii ATCC 49956(T) (the type species of the genus Roseomonas) was 93.4%. Strain 7515T-07(T) contained Q-10 as the ubiquinone and C18:1ω7c and C19:0 cyclo ω8c 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(T) is a representative of a novel species of the genus Roseomonas, for which the name Roseomonas aerophila sp. nov. is proposed. The type strain is 7515T-07(T) (=KACC 16529(T)=NBRC 108923(T)).
