Induction and production of specific extracellular lipases from selected microorganisms
Bibliographic record
Abstract
Induction of extracellular lipases from Pseudomonas fragi CRDA 037 and Geotrichum candidum was used to increase lipase production in a shorter period of time. Induction was performed using edibles oils such as olive oil, canola oil, fish oil and butter fat. Fermentation trials of the microorganisms in the selected media were done in order to optimize the production of lipases. Optimal lipase activity was obtained in the presence of butter fat (1%, v/v) for P. fragi which was cultivated at 15°C during 48 h, and fish oil (0.75%, v/v) for G. candidum incubated at 27°C for 56 h. The induced lipase extracts of P. fragi and G. candidum obtained after these fermentation trials were purified by 3.7 and 5.9-fold respectively using ultrafiltration, while the non-induced fractions were purified by 2.3 and 5.1-fold, respectively. Activities were evaluated using p-nitrophenyl esters such as p-nitrophenyl laurate and p-nitrophenyl palmitate. (Abstract shortened by UMI.)

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.
