Abstract

A Gram-positive, aerobic, rod-shaped, nonmotile, endospore-forming bacterium, designated Gsoil $349^T$, was isolated from soil of a ginseng field and characterized using a polyphasic approach. Comparative analysis of 16S rRNA gene sequences revealed that the strain Gsoil $349^T$ belongs to the family Paenibacillaceae, and the sequence showed closest similarity with Cohnella thermotolerans DSM $17683^T$ (94.1%) and Cohnella hongkongensis DSM $17642^T$ (93.6%). The strain showed less than 91.3% 16S rRNA gene sequence similarity with Paenibacillus species. In addition, the presence of MK-7 as the major menaquinone and $anteiso-C_{15:0},\;iso-C_{16:0},\;and\;C_{16:0}$ as major fatty acids suggested its affiliation to the genus Cohnella. The G+C content of the genomic DNA was 53.4 mol%. On the basis of its phenotypic characteristics and phylogenetic distinctiveness, strain Gsoil $349^T$ should be treated as a novel species within the genus Cohnella for which the name Cohnella panacarvi sp. nov. is proposed. The type strain is Gsoil $349^T\;(=KCTC\;13060^T=\;DSM\;18696^T)$.
