A Gram-negative, yellowish bacterial strain, designated Gsoil 1519T, 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 1519T belongs to the family Flexibacteraceae and is related to Spirosoma rigui KCTC 12531T (91.8 % similarity) and Spirosoma linguale LMG 10896T (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 1519T was 50.1 %. The detection of MK-7 as the predominant menaquinone and a fatty acid profile with C16 : 1
5c, summed feature 4 (C16 : 1
7c and/or iso-C15 : 0 2-OH), iso-C15 : 0 and C16 : 0 as the major acids supported the affiliation of strain Gsoil 1519T to the genus Spirosoma. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil 1519T 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 1519T (=KCTC 22263T=DSM 21099T).
