Aeromicrobium ginsengisoli sp. nov., isolated from a ginseng field

Strain Gsoil 098(T), a Gram-positive, non-spore-forming, non-motile coccus, was isolated from soil from a ginseng field in South Korea and characterized in order to determine its taxonomic position. 16S rRNA gene sequence analysis revealed that strain Gsoil 098(T) belongs to the family Nocardioidaceae, and the highest degrees of sequence similarity were found with Aeromicrobium marinum T2(T) (99.0%), A. panaciterrae Gsoil 161(T) (98.9%), A. alkaliterrae KSL-107(T) (98.4%), A. fastidiosum KCTC 9576(T) (98.1%) and A. erythreum NRRL B-3381(T) (97.5%). Chemotaxonomic analysis revealed that strain Gsoil 098(T) possesses menaquinone MK-9(H(4)) and predominant fatty acids C(16 : 0), 10-methyl C(18:0) and C(18:0). DNA-DNA hybridization results and physiological and biochemical tests clearly demonstrated that strain Gsoil 098(T) represents a distinct species. Based on these data, Gsoil 098(T) (=KCTC 19207(T) =JCM 14732(T) =GBS 39(T)) should be classified as the type strain of a novel Aeromicrobium species, for which the name Aeromicrobium ginsengisoli sp. nov. is proposed.
