Phenol metabolism by two microorganisms isolated from Amazonian forest soil samples
Bibliographic record
Abstract
Two microorganisms isolated from Amazonian forest soil samples and identified as Candida tropicalis and Alcaligenes faecalis were capable of degrading phenol (16 and 12 mM, respectively) at high salt concentrations (15% and 5.6%, respectively). Chromatographic and enzymatic studies revealed that each microorganism cleaved phenol at the ortho position with total phenol mineralization. 14C-phenol mineralization assays showed that both microorganisms assimilated about 30% of the total label. No phenol degradation metabolite (i.e., catechol, cis, cis-muconic acid) was detected in the intercellular medium. The presence of phenol hydroxylase (EC 1.14.13.7) and catechol 1,2-dioxygenase (EC 1.13.11.1) extracellular activity suggested that these microorganisms may secrete these enzymes into the extracellular medium.

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.
