Colour Removal and the Effect of Reactive Dyes on Growth Substrate Utilization by an Unacclimated Ethanol-Enriched Anaerobic Culture
Bibliographic record
Abstract
Abstract The cultures from an ethanol-enriched anaerobic master culture reactor were dosed with 0, 50, 100, 200, 400, 800, and 1600 mg/L of a mixture of three Procion reactive dyes: Red MX-8B, Red MX-5B, and Orange MX-2R, in order to study the colour removal and the inhibitory effect of dyes on the methanogenic degradation of ethanol that was added as a cosubstrate. The reduction in colour intensity, measured at 514 nm, was found to be similar to a trial using an inactivated culture. These results indicate that removal of colour by the unacclimated anaerobic population is due to adsorption of the dyes on the biomass. The dyes caused a competitive inhibition at doses above 200 mg/L on utilization of ethanol by the anaerobic bacteria.

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.
