Improved Production of Y-Decalactone from Castor Oil by UV Mutated Yeast <i>Sporidiobolus salmonicolor</i> (MTCC 485)
Bibliographic record
Abstract
γ-Decalactone (GDL; C 10 H 18 O 2 ) is an industrially important flavor compound having peachy fruit aroma and approved by FDA as a food additive. The aim of the present study is to enhance the production of γ-Decalactone by mutant strain of Sporidiobolus salmonicolor MTCC 485through batch cultivation using castor oil as substrate. Mutation studies were carried out using UV light and four potential mutant strains were developed (UV1, UV2, UV3 and UV4). Bioconversion of castor oil for the production of γ-Decalactone by obligate aerobic yeast S. salmonicolor was investigated in a 5 l bioreactor. Four mutant strains were shoed fast growth and higher production of γ-Decalactone when compared to Wild strain which produced 62.2 mg/l. maximum at 96 h. Among the four strains selected UV3 was produced 81.9 mg/l maximally at 96 h. It was showed 33% higher production of γ-Decalactone when compared to the wild strain.

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.
