A Gram-positive, non-spore-forming, rod-shaped, motile bacterium, designated strain DCY22T, was isolated from soil of a ginseng field in South Korea and characterized in order to determine its taxonomic position. 16S rRNA gene sequence analysis revealed that strain DCY22T belonged within the family Sanguibacteraceae, and highest levels of sequence similarity were found with Sanguibacter marinus 1-19T (96.8 %), Sanguibacter suarezii ST-26T (96.0 %), Sanguibacter inulinus ST-50T (95.9 %), Sanguibacter keddieii ST-74T (95.5 %), Terrabacter terrae PPLBT (94.0 %) and Terrabacter tumescens DSM 20308T (93.8 %). Chemotaxonomic investigations revealed that strain DCY22T possessed menaquinone MK-9, a common feature of members of the genus Sanguibacter. Predominant fatty acids were unknown ECL 13.961 (45.81 %), 17 : 0 anteiso (23.46 %), 18 : 0 iso (15.42 %) and unknown ECL 14.966 (8.70 %). The results of physiological and biochemical tests clearly demonstrated that strain DCY22T represents a novel species of the genus Sanguibacter, for which the name Sanguibacter soli sp. nov. is proposed. The type strain is DCY22T (=KCTC 13155T=JCM 14841T).
A maximum-parsimony tree based on 16S rRNA gene sequences showing the phylogenetic relationships between strain DCY22T and related species and a table detailing the cellular fatty acid profiles of strain DCY22T and related species are available as supplementary material with the online version of this paper.
