Effects of electromagnetic waves on parameters, hydration and in vitro antimicrobial activity of the Brassica oleracea L. var. italica Plenck. and water

Abstract

Our team has developed a device capable of emitting electromagnetic waves via a solenoid. Building on this breakthrough, our research endeavors to explore the effects of these waves on the weight and osmotic parameters of Brassica oleracea L. var. italic Plenck, specifically broccoli sprouts. These sprouts were subjected to various types of activated water infused with electromagnetic waves, with their weight measured in grams and their percentage composition analyzed. This study aims to elucidate the potential impact of electromagnetic waves on agricultural practices and nutritional outcomes. The findings present valuable insights into optimizing crop growth and enhancing nutritional value, thus holding promise for agricultural applications. In addition to nutritional aspects, contamination by pathogenic microorganisms poses a significant challenge in fruit and vegetable cultivation, particularly when organic fertilizers are employed. Mitigating microbial contamination in plant-based foods is paramount for preventing gastrointestinal and other infections, thereby safeguarding consumer health. In vitro studies were conducted to investigate the antimicrobial effects of electromagnetic waves across different frequencies. Water suspensions containing a density of 105 cells per milliliter of three microbial ATCC strains—Escherichia coli, Staphylococcus aureus, and Candida albicans—were utilized. These suspensions were exposed to electromagnetic radiation within the frequency ranges of 350-600 Hz (designated as frequencies F1) and 20-40 kHz (designated as frequencies F2), as well as combinations of both F1 and F2 frequencies, each lasting 15 minutes. Results indicated that the tested strains exhibited heightened sensitivity to exposures at 350-600 Hz and 20-40 kHz, leading to a decrease in cell viability by approximately 70% compared to untreated controls.
