title: Electrochemical evaluation of extremely-low frequency magnetic field effects on sulphate-reducing bacteria.
abstract: The effects of 50 Hz magnetic fields on sulphate-           reducing bacteria viability were studied electrochemically.           Two types of graphite electrodes (pyrolytic           and glassy carbon) covered with whole           bacterial cells behind a dialysis membrane were used           for electrochemical measurements. We found about           15% decrease of reduction peak current density           (which indicates desulphurization activity of the bacterial           cells - their metabolic activity) on cyclic voltammograms           after magnetic field exposure compared           to the control samples. We suppose that the           magnetic field does not influence the metabolic activity           (desulphurization) of sulphate-reducing bacteria           but most probably causes bacterial death.
