Abstract

The affect of modest imposed surface potentials on the adhesion of marine bacteria to an electrically conducting layer deposited on silica glass is recorded. A positive shift increased bacterial settlement, However, a negative shift in potential was extremely beneficial in reducing numbers of adhered bacteria. An applied surface potential of - 66 mV SCE resulted in the bacterial population decreasing to approximately 12% of that on the unchargedreference sample. There was no further significant decrease in the adheredbacterial population when the magnitude of the negative potential was increased. The potential was maintained with very little current flow (less than 0.25 nA mm(-2)). The results were not due to any effect of the material used acid therefore the technique could be useful for reducing bacterial fouling in man! situations, including medical applications.
