Baekduia soli gen. nov., sp. nov., a novel bacterium isolated from the soil of Baekdu Mountain and proposal of a novel family name, Baekduiaceae fam. nov.
Bibliographic record
Abstract
A taxonomic study was conducted on BR7-21 T , 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 14684 T , Solirubrobacter pauli ATCC BAA-492 T , Patulibacter minatonensis JCM 12834 T , with 93.8%, 92.4%, and 91.5% sequence similarity, respectively; each genus represented a family in the order Solirubrobacterales . Strain BR7-21 T 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(H 4 ) and MK-8(H 4 ). The major fatty acids were summarized as (C 16:1 ω7c /iso-C 15:0 2-OH), iso-C 16:0 , and C 17:0 cyclo. On the basis of polyphasic evidence, it was proposed that strain BR7-21 T 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 BR7-21 T (= KCTC 22257T = LMG 24797 T ). The family Baekduiaceae fam. nov. is proposed to encompass the genus Baekduia gen. nov.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
