Growth and Tolerance of Pleurotus ostreatus at Different Selenium Forms
Bibliographic record
Abstract
Selenium is an important element in physiological and metabolic processes. Due to low Se concentration in most of the soils, strategies as enrichment and biofortification have been used to increase its incorporation in food. The fungus has capacity to absorb, accumulate and transform Se inorganic into organic compounds. However, the concentration and chemical forms of Se used for enrichment can affect the mycelial growth and mushrooms production. Thus, the aim of this study was to analyze the capacity of Pleurotus ostreatus in absorb, accumulate and tolerate growing concentrations of different Se chemical forms. In the disc of agar with mycelium was added 20 mL of PDA medium and Se concentration (0-200 mg L-1) in the forms of sodium selenite, sodium selenate or selenomethionine (SeMet). The greatest inhibition of mycelial growth and biomass production were observed in highest Se concentration. Regardless of the Se level, SeMet and sodium selenite were more harmful to the P. ostreatus growth than sodium selenate. However, the highest Se accumulation in the mycelium was observed in culture medium with sodium selenite. Thus, Se supplementation in the forms of sodium selenite was more indicated to enrichment of P. ostreatus mushrooms than sodium selenate and SeMet.

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.
