[Rapid determination of internal resistance in an electricigenic microorganism reaction system].

Internal resistance (R(int)) is an important parameter for kinetic studies on an electricigenic microorganism reaction system (EMRS). The traditional polarization curve measurement method is too laborious and tedious, usually leads to remarkable disturbance on system running. An improved method was put forward in this study, by decreasing the adjustment range of the external resistance value (R(ext)).
