Study on modified ionic exchanging resin immobilization of laccase and its kinetic properties
Bibliographic record
Abstract
Epoxy-modified acrylic have an epoxy group,which can react with an amino,a nucleophilic group on the protein,under mild conditions to achieve its immobilized.This paper studies the optimization of modified ionic exchanging resin on immobilization of laccase and enzymatic characterization.The results show that the immobilized enzyme activity is best under such conditions:the ammonium sulfate concentration 1.5mol·L-1,the amount of enzyme 0.2U·g-1,pH 6.5,temperature 35℃,fixed 3hours.At this time,vitality specific activity and activity recovery are 0.026 4U·g-1and 3.67%.The optimal conditions of immobilized enzyme catalyzed chemical reaction are as follows:temperature 45 ℃,pH 4.5,Km 1.233×10-3 mmol·L-1.The immobilized enzyme activity was inhibited with iron and calcium ions between the 4×10-3 to 4×10-4 moL·L-1,is activated between the 4×10-5 to 4×10-6 mol·L-1.

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.
