Abstract

Microbial biofilms are implicated with industrial fouling, corrosion, and hygiene problems. Here, we outline electrochemical control of microbial biofilm accumulation on marine infrastructures preventing biofouling without generating toxic substances. Marine bacteria were killed electrochemically by applying a potential of 1.2 V using conductive paint and TiN film electrode. Most of the cells on the electrode were desorbed within 30 min by applying 0.6 V vs. Ag/ AgCl. Prevention of bacterial cell accumulation can be performed by applying alternating potentials. Electrochemical control of bacterial cell accumulation on the electrode was achieved by applying an alternating potential of 1.2 and -0.6 V vs. Ag/AgCl. This method does not result in generation of chlorine or change pH. Electrochemical control of bacterial cell accumulation on electrodes will be applicable not only for seawater applications but also for fresh water systems. This disinfection system may also be used in food and medical process.
