Testing antimicrobial effects of tea-tree oil using S. cerevisiae and bread mold
Bibliographic record
Abstract
Tea tree oil (TTO) is a naturally occurring chemical found extracted from the leaves of a tree called narrow-leaved paperbark. It is well known as an antiseptic, however, its potential as a natural household cleaning agent has not been thoroughly examined yet. We were interested in examining the anti-fungal properties of TTO, especially on common bread mould, spores of which are common to households. This study used fresh-baked white bread as media to observe the effects of TTO at 0.06% and 0.24% concentrations on mold spore formation and 0.25% TTO on yeast fermentation. It was concluded that TTO can inhibit mold growth at the lowest of 0.06% but did not reduce (p=0.07) yeast CO2 production at 0.25% concentration. The data highlights the efficacy of TTO against household mould and based on our yeast results is potentially not toxic at low concentrations, but more studies are required with a variety of mould species and concentrations to better understand the use of TTO as a cleaning agent.

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.
