Cohnella panacarvi sp. nov., a xylanolytic bacterium isolated from ginseng cultivating soil

A Gram-positive, aerobic, rod-shaped, nonmotile, endospore-forming bacterium, designated Gsoil 349T, 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 349T belongs to the family Paenibacillaceae, and the sequence showed closest similarity with Cohnella thermotolerans DSM 17683T (94.1%) and Cohnella hongkongensis DSM 17642T (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 349T 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 349T (=KCTC 13060T = DSM 18696T).
