Abstract
Sodium di(2-ethylhexyl) sulfosuccinate, referred to as Aerosol-OT or AOT, was used to remove lysozyme from an aqueous phase via reverse micellar extraction and precipitation method. For both methods, when the surfactant was in excess, a complete removal of lysozyme from the aqueous phase was obtained at the values of pH below the pI of lysozyme. However, for the reverse micellar method, a solubilization limit of lysozyme in the organic phase was observed, and a white precipitate was formed at the aqueous-organic interface. This observation suggested using AOT directly as a precipitating ligand. The lysozyme precipitated with AOT was fully recovered, with its original enzymatic activity, using acetone as a recovery solvent. A mechanism is suggested to explain the solubilization of lysozyme in an AOT reverse micellar system. It is shown that a direct precipitation method can be used with advantage instead of using the reverse micellar extraction method to recover lysozyme from an aqueous phase.

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 it
