The assessment of Eremothecium oil biological activity via kinetics modelling revealed valid positive correlations between level of bacterial multiplication and lag-phase prolongation under different concentrations (from 0.49 to 7.81 µL/mL). Toxicity intensity correlated with phenyl ethanol (R = –0.9; strong negative association), geraniol (R = 0.6; moderate positive association), nerol (R = –0.55; moderate negative association), linalool (R = –0.74; strong negative association), and total monoterpene alcohol (R = 0.5; moderate positive association) content.
