Models to optimise bioengineering of banana wastes to animal feeds and fertilisers
Bibliographic record
Abstract
Microbial growth models are usually employed to describe the growth kinetics of microorganisms under optimised operational conditions. Much time and resources are involved in running central composite or Box–Behnken full factorial designs of the experiment (DoEs) before the optimum conditions are attained. In this study, a Taguchi model (two-level) was used for DoEs and kinetic parameters derived from the mathematical models were used for process optimisation. This resulted in running less ‘robust’ anaerobic digestion experiments for the varying selected parameters – that is, pH and temperature. Chapman–Richards model results were considered to represent experimental data and were compared with the kinetic parameters derived from the Bergter, Andrews and Contois models. Also, a pure population of Saccharomyces cerevisiae (Saf-instant) was used, unlike in many studies where mixed populations are employed for anaerobic digestion. From the model results, a pH of 4·6–5·6 and a temperature of 25–30°C were considered optimum for S. cerevisiae anaerobic growth on banana waste. Chemical characterisation of the digested banana wastes under optimised conditions indicated an increase in proteins and lipids by 7 and 5%, respectively, and an approximately 8% mineral content increase was also noted. The waste could also be used as a nutrient-rich fertiliser and chicken feed supplement.

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.
