| Abstract | A taxonomic study was conducted on BR7-21T, a bacterial strain isolated from the soil of a ginseng field in Baekdu Mountain. Comparative studies of the 16S rRNA gene sequence showed that the isolate was most closely related to Conexibacter woesei DSM 14684T, Solirubrobacter pauli ATCC BAA-492T, Patulibacter minatonensis JCM 12834T, with 93.8%, 92.4%, and 91.5% sequence similarity, respectively; each genus represented a family in the order Solirubrobacterales. Strain BR7-21T was Gram-reaction positive, non-spore forming, aerobic, non-motile, and short rod-shaped. It grew well on half-strength R2A medium. The G + C content of the genomic DNA was 73.9%. It contained meso-diaminopimelic acid in the cell wall and the major menaquinones were MK-7(H4) and MK-8(H4). The major fatty acids were summarized as (C16:1 ω7c/iso-C15:0 2-OH), iso-C16:0, and C17:0 cyclo. On the basis of polyphasic evidence, it was proposed that strain BR7- 21T should be placed in a new genus and species, for which the name Baekduia soli gen. nov., sp. nov. was proposed with the type strain BR7-21T (= KCTC 22257T = LMG 24797T). The family Baekduiaceae fam. nov. is proposed to encompass the genus Baekduia gen. nov. |
