Generation of a Highly Stable Reusable Biocatalyst by Entrapment of an Oligomeric Enzyme in Ultra-Large-Pore Mesoporous Silica*
Bibliographic record
Abstract
Phenylalanine ammonia lyase (PAL, E.C.4.3.1.24), was entrapped in ultra-large-pore mesoporous silica (ULPS, 23 nm pore diameter) generating a recyclable, separable biocatalyst. The entrapped ULPS-PAL materials showed excellent stabilization, even after significant exposure to prolonged heating. Additionally, the entrapped ULPS-PAL materials showed extremely high catalytic activity in the deamination of l-phenylalanine to trans-cinnamic acid in aqueous solution and were recovered and recycled up to five times without any observable loss in activity. This approach is simple and capitalizes on the facile synthesis and easy recoverability of mesoporous silicas to generate a stable, reusable PAL-based biocatalyst.

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.
