Abstract

The mechanism of electrochemical sterilization of sulfate reduced bacteria (SRB) under anaerobic conditions was investigated by electrochemical method and microbiological method. The cyclic voltammetry analysis showed that the electrochemical oxidation of SRB occurred around 0.40V versus saturated calomel electrode (SCE), and the peak current was around 10^-A. With increasing the scan rate and culture time, the peak current changed. The shift range of peak current was within 50mV. When a potential of 0.40V (SCE) was applied to the graphite electrode, the bacteria were almost sterilized after 10 minutes. This sterilization effect was due to the electrochemical oxidation of intracellular coenzyme A in the cell of SRB.
