Phenolic EO compounds delay the microorganism growth curves in a concentration-dependent manner.

<p>Various concentrations of the phenolic EO compounds were used to test their impact on the bacterial growth curves. The bacterial growth curves in the presence of various phenolic EO concentrations (hollow diamond, triangle, square, and circle) were compared to each control (solid circle). Broth-only treatment served as a negative control (solid square). Y axis, OD600; X axis, time (sec).</p>
