Bacterial Translational Motion on the Electrode Surface under Anodic Electric Field

Application of an electric field (alternating or cathodic polarization) has been suggested as a possible mean of controlling biofilm development. Bacteria on an anodically polarized surface were shown to be active and highly motile when compared with a nonpolarized condition, but no quantitative information on bacterial motion has been reported. This study investigated the effects of environmental conditions (current density and ionic strength) on the translational motion of P. aeruginosa PAO1 cells under an anodic electric field using a quantitative tracking method. Bacterial displacement for 10 s was found to be approximately 1.2 mu m, irrespective of dynamics of bacterial communities differed under varied current exhibit a more oscillating (subdiffusive) at high current density. (superdiffusive) decreased. Bacterial movement decreased with interactions. The motion of bacterial communities on an with possible mechanisms. In addition, the control of biofilm cells under anodic polarization.
