Abstract:

   Natural electric, magnetic and electromagnetic fields have a regulating effect on living organisms, helping to normalize vital processes and optimize their interaction with the environment. Scientists emphasize that artificial fields can change various characteristics of living organisms, affecting their vital activity and viability both positively and negatively. The aim of the work was to experimentally study the effect of an alternating electromagnetic field (EMF) on the marine microbiota (suspensions of Black Sea algal viruses and liquid cultures of Black Sea microalgae) with using a laboratory setup created at the Institute of Natural and Technical Systems.

   The laboratory setup allows us to create an EMF with a frequency in the range of 25–150 Hz and generate an alternating magnetic field of 0.1–0.545 G. The impact of EMF on marine microbiota was recorded by changes in the infectious titer of Black Sea algal viruses and sensitivity (resistance) to viral lysis of cultures of Black Sea microalgae Tetraselmis viridis and Dunaliella viridis. Under the influence of EMF, a decrease in the infectious titer in algal viruses and an increase in resistance to viral lysis in microalgae by 1–2 orders of magnitude were established. The values of changes in the indicated biological characteristics depended mainly on the duration of the electromagnetic load (from a day or more) and its physical characteristics (frequency and signal level), as well as the value of the initial infectious titer of algal viruses and the species that determines the sensory to EMF used in the experiments with microalgae cultures.

Keywords: electromagnetic field (EMF), algal viruses, microalgae Tetraselmis viridis and Dunaliella viridis.
