Enzymatic synthesis of octyl glucoside catalyzed by almond β-glucosidase in organic media
Bibliographic record
Abstract
The synthesis of n-octyl-β-D-glucopyranoside can be performed by direct condensation of 1-octanol and glucose, catalyzed by immobilized almond beta-glucosidase, using solid glucose suspended in 1-octanol as a reaction media. Both the rate of reaction and the conversion could be enhanced by using acetonitrile and N,N-dimethylformamide (DMF) as co-solvents, the latter giving the best results. The rate of reaction was dependent on the concentration of DMF and on the initial water activity (a w ), with higher water activity fostering faster reactions. The rate increased with DMF concentration, up to 20% DMF, but diminished rapidly at higher concentrations. Product concentration could be increased from 40 to 100 mM by going from 0 to 20% DMF; however, it was not sensitive to the initial water activity.Key words: β-glucosidase, alkyl glycosides, reverse hydrolysis, water activity, organic solvent.

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.
