Solubilization limit of lysozyme into DODMAC reverse micelles
Bibliographic record
Abstract
Dioctyldimethyl ammonium chloride (DODMAC) was used to form reverse micelles and to extract lysozyme from an aqueous solution into an organic phase. The solubilization behavior of lysozyme into a DODMAC reverse micellar phase was examined in terms of the temperature, the type of cations in the aqueous phase, and the surfactant concentration in the organic phase. Complete removal of lysozyme from the aqueous phase was obtained when the pH was set one unit higher than the pI of the protein. However, it was found that there is a solubilization limit of lysozyme in the organic phase. Not all the lysozyme extracted out of the initial aqueous phase was solubilized into the DODMAC reverse micellar phase, resulting in the formation of white precipitate at the aqueous-organic interface. Temperature has a negligible effect on the solubilization limit of lysozyme. The value of the solubilization limit is a strong function of the type of cations present in the aqueous phase, indicating an important role of lysozyme-cation interactions on the extraction process. An increase in the DODMAC concentration from 100-200 mM resulted in little change in the highest concentration of lysozyme obtained in the organic 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.
