Kinetic Study on Decolorization of the Dye Acid Orange Using the Fungus Phanerochate Chrysosporium
Bibliographic record
Abstract
A dye decolorizing fungal strain, Phanerochaete chrysosporium MTC 787 was used in batch experiments for decolorization of the dye, Acid orange10. Effects of initial substrate (dye) and fungal concentrations on the rate and extent of dye decolorization were investigated. The initial pH and oxidation–reduction potential (ORP) was kept at 4.5 and ?250 mV, respectively. The rate and extent of dye decolorization increased with increasing dye concentration up to 100 g l?1 and then decreased for larger dye concentrations. The rate of enzyme utilization and dye decolorization also increased linearly with increasing initial biomass concentration. A kinetic model describing the rate of enzyme utilization and substrate inhibition as function of the initial substrate and flow rate was developed. The kinetic constants were determined using the experimental data. The initial biomass should be above 3.2 x 105cell/ml to obtain high rates and decolorization percentage and to avoid substrate inhibition.

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.
