Influence of 50 Hz electromagnetic field on the yeast (saccharomyces cerevisiae) metabolism

In this paper an experimental study regarding the behavior of the yeast subjected to the electric field action at a frequency of 50 Hz is presented. The aqueous suspension was prepared from distilled water - 94 ml, dry yeast - 5 g and sugar - 1 g. The dielectric spectroscopy method was used in order to characterize the contributions of proteins to the dielectric properties of the suspension. The complex permittivity and conductivity were measured at 50 Hz at room temperature. The applied electric field varies between 1 V/cm and 6 V/cm (effective value). Conductivity and permittivity are found to increase, resulting in variations in magnitude of the applied field.
