Isolation and screening of fungi to determine potential for ammonia nitrogen treatment in wastewater
Bibliographic record
Abstract
Twenty-two fungi were studied to determine the potential for development of fungal nitrogen treatment (FNT) technology for municipal wastewater. Fungal nitrogen treatment has been hypothesized to have several significant advantages over bacterial nitrification–denitrification systems. The fungi were isolated from the biological nutrient reactor at the Gold Bar Wastewater Treatment Plant in Edmonton, Alberta, Canada. Fungi were screen for nitrogen treatment potential using an aerobic 3 day ammonium concentration decrease test. Seven fungi were found to have potential for nitrogen or phosphorus treatment. The highest average ammonium decreased was 59% with an average initial concentration of 22 mg N L –1 . Fungal nitrogen treatment was also characterized by a lack of production of nitrate or nitrite under aerobic conditions. Data analysis indicated, the ammonium decrease was not consistent with nitrogen assimilation.Key words: fungi, biological nutrient removal, ammonium, nitrification, denitrification.

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.
