Original Paper


A Gram-stain-negative, strictly aerobic, non-motile, ivory colored and rod-shaped bacterium (designated Gsoil 652T) isolated from ginseng cultivating soil, was characterized using a polyphasic approach to clarify its taxonomic position. Strain Gsoil 652T was observed to grow optimally at 30 °C and at pH 7.0 on R2A agar medium. Phylogenetic analysis, based on 16S rRNA gene sequences similarities, indicated that Gsoil 652T belongs to the genus Caballeronia of the family Burkholderiaceae and was most closely related to Caballeronia choica LMG 22940T (98.9%), Caballeronia udeis LMG 27134T (98.9%), Caballeronia sordidicola LMG 22029T (98.2%) and Caballeronia humi LMG 22934T (98.1%). The DNA G+C content was 62.1 mol% and Q-8 was the major isoprenoid quinone. The main polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, unidentified aminophospholipid, and unidentified phospholipid. The predominant fatty acids were C16:0, C17:0 cyclo and C19:0 cyclo ω8c. The DNA–DNA relatedness value between strain Gsoil 652T and closely related type strains of Caballeronia species were less than 36.0%. Moreover, strain Gsoil 652T could be distinguished phenotypically from the recognized species of the genus Caballeronia. The novel isolate, therefore, represents a novel species, for which the name Caballeronia ginsengisoli sp. nov. is proposed, with the type strain Gsoil 652T (= KACC 19441T = LMG 30326T).
