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

Abstract

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.

Emerging diagnostic and therapeutic applications of non-ionising electromagnetic radiations in Oncology

“…Electromagnetic fields (EMFs) can act on cellular chemotactic communications and gene expression [51]. Low frequency pulsed EMF have been shown to influence root growth of plants at frequencies of 60 Hz with fields of 350V /m and 450V / m, [52] metabolism of fermenting yeast cells, increasing ethanol production by 25% -30% [53] and even cause apoptosis of tumor cells [54].…”

Recycled Polypropylene/Strontium Ferrite Polymer Composite Materials with Electromagnetic Shielding Properties

“…Since electromagnetic waves can also harm people, the most effective EMI shielding technologies have demanded increased attention [ 1 , 2 ]. Electromagnetic radiation pollution can lead to damage to human health [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ] and living matter [ 12 , 13 , 14 , 15 , 16 ], so it is urgently necessary to reduce it by researching and designing different new materials effective for this purpose. These materials must synergistically ensure a good attenuation of electromagnetic waves [ 17 , 18 ] and high resistance to the action of fungi [ 12 , 13 , 14 , 15 , 16 , 19 , 20 ], environmental conditions [ 21 , 22 , 23 , 24 , 25 , 26 ], mechanical stresses [ 27 , 28 ], excellent dielectric, magnetic and electromagnetic characteristics [ 29 , 30 , 31 , 32 ], and high resistance to the action of microwaves and UV radiation [ 33 ].…”

These conditions can be ensured through polymer-based composite materials, which have excellent mechanical properties and thermal stability, as well as high resistance to environmental conditions.…”

Flexible Electromagnetic Shielding Nano-Composites Based on Silicon and NiFe2O4 Powders

“…The continuous increase in electricity production, due to the ever-increasing demand of consumers, which generates electromagnetic fields, leads to an increase in the electromagnetic pollution of the environment in various rooms/spaces/offices [2]. Electromagnetic pollution, continuously increasing, can even lead to the deterioration of human health [3][4][5][6] and living matter [7][8][9][10][11][12][13][14]. Reducing the electromagnetic pollution created in different spaces with different uses can be achieved by researching and designing different new materials that are effective for this purpose [15,16].…”
