The study isolated a Gram-negative, rod-shaped, non-motile bacterium from the soil of a ginseng field in Daejeon, South Korea and characterized it to determine its taxonomic position. Phylogenetic analysis, based on the 16S rRNA gene sequence, revealed that strain $MK06^T$ belongs to the family Xanthomonadacea, and showed the highest degree of sequence similarity to Stenotrophomonas rhizophila $e-p10^T$ (98.6%), Xanthomonas campestris LMG $568^T$ (98.0%), Stenotrophomonas maltophilia ATCC $1d3637^T$ (97.3%), and Stenotrophomonas humi $R-32729^T$ (96.9%). Chemotaxonomic data revealed that strain $MK06^T$ possesses ubiquinone Q-8 as the predominant respiratory lipoquinone, which is common in the genus Stenotrophomonas, and that the predominant fatty acids were 15:0 iso (41.1%), 15:0 anteiso (12.6%), and 17:1 iso ${omega}9c$ (8.6%). The results of physiological and biochemical tests clearly demonstrated that strain $MK06^T$ represents a distinct species and supported its affiliation with the genus Stenotrophomonas. Based on these data, $MK06^T$ (KCTC, $22893^T$; JCM, $16536^T$; KEMB, $9004-002^T$) should be classified as the type strain for a novel species, for which we propose the name Stenotrophomonas panacihumi sp. nov.
