Phenol removal from aqueous solution by fungal peroxidases
Bibliographic record
Abstract
Aromatic compounds may be removed from aqueous solution by extra-cellular peroxidase enzymes that target specific classes of aromatic compounds. Phenol removal by commercially available extra-cellular enzyme, Arthromyces ramosus peroxidase (ARP), was studied at several temperatures and pH values. The optimal pH for phenol removal was found to lie within the range of pH 7 to 8, and was not affected by temperature. At neutral pH, phenol removal increased with decreasing temperature within the range of 0 °C to 30 °C. Coprinus cinereus peroxidase (CIP) was produced by Coprinus cinereus UAMH 4103 in a stirred fermentor; the fermentor broth was filtered, and used in phenol removal tests at room temperature. The impurities remaining in the crude enzyme solutions following filtration produced a beneficial effect on phenol removal from the buffered aqueous solution. However, greater phenol removal was observed in un-buffered solutions compared to removals achieved in solutions that contained phosphate buffer. Key words: phenol removal, Coprinus cinereus peroxidase, Arthromyces ramosus peroxidase, enzymatic treatment.

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.
