Presence of 2,4-D-catabolizing Bacteria in a Japanese Arable Soil that Belong to BANA (Bradyrhizobium-Agromonas-Nitrobacter-Afipia) Cluster in .ALPHA.-Proteobacteria.
Bibliographic record
Abstract
We isolated the 2, 4-D-catabolizing bacterial strain RD5-C2 from Japanese upland soil that had no history of 2, 4-D exposure.RD5-C2 could use 2, 4-D as the sole carbon and energy sources for their growth.Phylogenetic analyses based on 16S rDNA sequencing revealed that RD5-C2 was a member of the BANA(Bradyrhizobium-Agromonas-Nitrobacter-Afipia)cluster in the α subdivision of the class Proteobacteria.The gene sequence of RD5-C2 most closely matched that of Bradyrhizobium sp.and also closely related to those of 2, 4-D-catabolizing α-Proteobacteria previously isolated from pristine environments of Hawaii, northern Canada and central Chile.This is the first instance that 2, 4-D-catabolizing bacteria in that phylogenetic group was isolated from an arable soil environment.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
