Nanoporous Sol-Gel Supports Enzymatic Hydrolysis of Chlorophyll in Organic Media
Bibliographic record
Abstract
Entrapment of membrane proteins is a challenging task compared to that involving soluble proteins. Chlorophyllase, a membrane protein, was entrapped in nanoporous tetramethoxysilane (TMOS)-derived sol-gel, demonstrating higher protein mass and activity yield than that in polysaccharide gel and hybrid gel. Both sol-gel formulation process and chemistry may affect apparent activity of sol-gel entrapped chlorophyllase, thus need to be taken into account to improve entrapped chlorophyllase activity. Even though the external transfer of chlorophyll to the sol-gel matrix can be minimized by increasing mixing rate up to 150 rpm, internal diffusion of chlorophyll in nanoporous sol-gel was largely restricted, confirmed by the measured diffusion coefficient of 10 -14 m 2 /s. The apparent activity was also affected by the availability of hydrophobic chlorophyll substrate within the hydrophilic gel, which was controlled by partitioning of chlorophyll between a water/organic solvent medium and the gel phase.

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.
