Simultaneous production of phycobiliproteins and carbonic anhydrase by <i>Spirulina platensis</i> LEB‐52
Bibliographic record
Abstract
Abstract The simultaneous production of carbonic anhydrase and the phycobiliproteins, C‐phycocyanin and allophycocyanin, was evaluated during the cultivation of Spirulina platensis using Zarrouk's medium in its non‐diluted (100 % ZM) and diluted to 20 % (v/v) (20 % ZM) forms. In both media, Spirulina simultaneously produced carbonic anhydrase and phycobiliproteins. For the phycobiliproteins’ production, higher concentrations (mg/g) of C‐phycocyanin and allophycocyanin were obtained when 100 % ZM was used. For carbonic anhydrase production, higher concentrations (U/g) were obtained on the 6th day of cultivation in both culture media. 100 % ZM promoted greater productions of these bioproducts, and, for simultaneous obtainment, the cells should be harvested after 21 days, obtaining concentrations of 137.4 mg/g C‐phycocyanin, 104.4 mg/g allophycocyanin, and 26.6 U/g carbonic anhydrase.

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.
