sp. nov., isolated from soil of a ginseng field.

A bacterial strain designated as G188 was isolated from ginseng field soil in the Republic of Korea. Phylogenetic analysis of 16S rRNA gene sequences showed that strain G188 formed a distinct lineage within the genus family , order . Sequence similarity revealed that strain G188 was most closely related to IR27-S3 (97.7 % 16S rRNA similarity). The genome size of strain G188 was 4 901 775 bp, and the genomic DNA G+C content was 72.3 mol%. The average nucleotide identity and DNA-DNA hybridization values with other species were less than 75.6 and 20.1 %, respectively. The main fatty acids of strain G188 were C, C 8 and iso-C. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, and phosphatidylinositol, and the major respiratory quinone was menaquinone 8, supporting that strain G188 was affiliated with the genus . Based on biochemical, chemotaxonomic and phylogenetic analyses, the novel species G188 (KACC 21695=LMG 31733) is proposed.
