In this study, it could be found that the microbial movement in soil under electric field mainly occurred by electrophoresis and electroosmosis. The contribution of electrophoresis on the microbial mobility and flux was generally higher than that of electroosmosis. In the electrokinetic(EK) bioremediation of a pentadecane-contaminated soil, the microbial population increased simultaneously at anode and cathode regions of the soil specimen because both electrophoresis and electroosmosis affected on the microbial movement. After initial operation, the microbial population was high in order of anode, middle, and cathode regions due to their negatively-charged surface and oxygen generation at anode. However, the uniform contaminant removal was achieved by the microbial movement with two-directionality.

The use of electrokinetic injection and transport for the distribution of an NAPLs-degrading microorganism in a sandy soil bed was studied. After the injection of the cell into cathode side of bed, an electric current was applied. The transport of cell though the sandy soil was achieved by electokinetics, mainly by electrophoresis, The pH control in electrode chamber plays un important role to achieve desirable cell transport because H$^{+}$ generated at anode is toxic or inhibits the transport of cells. Electokinetic distribution rate of bacterial cells changed depending on the applied electric current and pH. The degradation of diesel by electrokinetically transport cells were monitored.d.
