研究の主なアウトカム(著者による)

The data showed a 15% decrease of reduction peak current density (which indicates metabolic activity of the bacterial cells) on cyclic voltammograms after magnetic field exposure compared to the control samples. The authors suppose that the magnetic field does not influence the metabolic activity of sulphate-reducing bacteria but most probably causes bacterial death.
