Development of Stable Redox Complexes to Mediate Delignification of Kraft Pulp by Laccase
Bibliographic record
Abstract
The use of laccase and mediators to delignify and bleach kraft pulp is now well documented. Several nitrogen-containing aromatic compounds have been shown to mediate the oxidation of lignin by laccase. In order to apply this technology in the kraft pulp industry, development of cost-effective mediators and laccases are of prime importance. Our electrochemicalstudies on the interaction between laccase, mediator and lignin indicate that effective mediators must behave like true catalysts, i.e. they must be reversibly reduced by lignin so that the mediator will be continuously regenerated and made available for further cycles of oxidation by laccase. We report on the use of transition metal complexes in combination with laccase to mediate catalytic delignification of kraft pulps. Due to their redox properties and stability, these metal complexes can be recycled many times for pulp delignification.

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.
