Biological effects of magnetic fields: studies with microorganisms

Abstract

Five bacteria and one yeast were grown in magnetic fields of 50–900 gauss with frequencies of 0–0.3 Hz and square, triangular, or sine waveform. Growth of these microorganisms could be stimulated or inhibited depending upon the field strength and frequency of the pulsed magnetic field. Spore germination and mutation frequency were unaffected by the magnetic fields used in this study.
