A Gram-negative, yellowish bacterial strain, designated Gsoil 1519(T), was isolated from soil of a ginseng field in Pocheon province (South Korea) and characterized using a polyphasic approach to ...determine its taxonomic position. Comparative 16S rRNA gene sequence analysis showed that strain Gsoil 1519(T) belongs to the family 'Flexibacteraceae' and is related to Spirosoma rigui KCTC 12531(T) (91.8 % similarity) and Spirosoma linguale LMG 10896(T) (91.5 % similarity). Phylogenetic distances from any other recognized species within the family 'Flexibacteraceae' were greater than 14.7 %. The G+C content of the genomic DNA of strain Gsoil 1519(T) was 50.1 %. The detection of MK-7 as the predominant menaquinone and a fatty acid profile with C(16 : 1)omega5c, summed feature 4 (C(16 : 1)omega7c and/or iso-C(15 : 0) 2-OH), iso-C(15 : 0) and C(16 : 0) as the major acids supported the affiliation of strain Gsoil 1519(T) to the genus Spirosoma. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil 1519(T) should be classified in the genus Spirosoma as a representative of a novel species, for which the name Spirosoma panaciterrae sp. nov. is proposed. The type strain is Gsoil 1519(T) (=KCTC 22263(T)=DSM 21099(T)).
