Electrochemical Study of Interaction of Bacteria and Clay

Koffi OE, Bile BE, Bengourram J, Tankiouine S, Latrache H and Chtaini A

The electrochemical behavior of bacteria, such Staphylococcus aureus, at clay modified carbon paste electrode is reported. The influence of variables such as the accumulation time, optical density (OD) was tested by square wave voltammetry (SWV), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The interaction of bacteria and metal surface is discussed. A novel clay electrode (Arg-E) was fabricated for directly determination of bacteria in water or whole blood samples. The optical density of bacteria (OD) was determined and its evolution with the current density was plotted.
