Effect of (−)-limonene and (+)-α-pinene on luciferaseenzymatic activity of P. luminescens in the E. coli MG1655 (pXen7) strain. Kinetics of changes in mean values of light emission (in RLU) at various chemical concentrations: (◆) 0 μM (control); (+)-α-pinene () 1 μM, (▲) 10 μM, and (+) 100 μM; (−)-limonene (🞶) 1 μM, (⬤) 10 μM, and (×) 100 μM. The ordinate axis shows the enzymatic activity of luciferase. The abscissa axis shows the time of incubation at 22 °C.
