Abstract
Sophorolipid production was studied using Candida bombicola ATCC 22214. Solid and liquid alkanes or fatty acids were used as lipophilic substrates in shake flask experiments. With a few of these substrates, there was a significant amount of direct incorporation into the sophorolipid products. Of all substrates tested, only hexadecane and heptadecane resulted in the exclusive production of crystalline, diacetylated lactone sophorolipids that contained a single type of hydroxy fatty acid. It was determined that the presence of a single type of sophorolipid structure was necessary to obtain crystalline products. It was also possible to obtain the crystalline product using larger scale experiments with hexadecane. The direct incorporation of hexadecane was shown to result in increased sophorolipid production efficiency with hexadecane being used as the sole source of the hydroxy fatty acids needed for sophorolipid production and the hydrophilic substrate being used as a source of energy. With the other lipophilic substrates, this efficiency was lost because there was appreciable de novo synthesis of the fatty acids.

How this classification was reachedexpand
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.
