Abstract

fetched live from OpenAlex

Bacteria of the species Pseudomonas putida are ubiquitous soil inhabitants, and a few strains are able to thrive in the presence of extremely high concentrations of toxic solvents such as toluene and related aromatic hydrocarbons. Toluene tolerance is multifactorial in the sense that bacteria use a wide range of physiological and genetic changes to overcome solvent damage. This includes enhanced membrane impermeabilization through cis to trans isomerization of unsaturated fatty acids, activation of a stress response programme, and induction of efflux pumps that expulse toxic hydrocarbons to the outer medium. The most relevant element in this toluene tolerance arsenal is the TtgGHI efflux pump controlled by the TtgV regulator. We discuss here how TtgV controls expression of this efflux pump in response to solvents.

Full frame distilled prediction

Teacher imitation

Not 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.
