TitleCohnella damensis sp. nov., a motile xylanolytic bacteria isolated from a low altitude area in Tibet
PublicationInfo J. Microbiol. Biotechnol.2010 ; 20(2): 410~414
AbstractA bacterial strain, 13-25T with xylanolytic activity isolated from a single present soil sample, was characterized with respect to its phenetic and phylogenetic characteristics. The cells of the isolate are gram staining variable rods. The predominant fatty acids are anteiso-C15 : 0, iso-C15 : 0 and iso-C16 : 0, the major respiratory quinone is menaquinone (MK-7), with a polar lipid profile with unknown aminophospholipids. The G+C content is 54.3 mol%. The 16S rRNA gene sequence analysis indicates that this organism belongs to the genus Cohnella, with Cohnella panacarvi as the closest phylogenetic neighbor. Low levels of 16S rRNA gene sequence similarity (<97.0%) with respect to other taxa with published names and the identification of distinctive phenetic features in the isolate indicate that the strain 13-25T represents a novel species of the genus Cohnella, for which the name Cohnella damensis sp. nov. is proposed. The type strain is 13-25T (=CCTCC AB 208103T =KCTC 13422T).
