The relevance of the study of the evolutionary mechanisms of the interaction of microorganisms with electromagnetic radiation of natural origin is substantiated. It is based on the unresolved problem of assessing the controlling role of microwave electromagnetic radiation of natural origin in wildlife. The resolution of this problem is directly related to the assessment of the impact on organisms and microorganisms, in particular, microwave radiation of technogenic origin. The purpose of the study was a comparative assessment of the modifying effect on microorganisms of simulated natural and technogenic microwave electromagnetic radiation of low intensity based on the results of their mass spectroscopy. Six strains of microorganisms were studied: Escherichia coli ATCC 25922, Enterococcus faecalis ATCC 19433, Enterococcus faecium ATCC 19434, Staphylococcus aureus ATCC 43300, Staphylococcus aureus ATCC 12600, Klebsiella pneumoniae ATCC 700603. AIMT-1M hardware and software device was used to simulate natural and technogenic electromagnetic radiation. Mass spectroscopy of the biomolecules of these microorganisms revealed an asymmetric nature of the distribution of the intensity of ion fluxes according to the ratio of the ion mass to its charge when microorganisms are exposed to various types of electromagnetic radiation. An important feature of the obtained results is the nature of the interaction of microorganisms with the electromagnetic radiation used in the experiment, which does not destroy the structure of biomolecules. The most pronounced changes in the intensity of ion fluxes in the mass spectra a day after exposure to microorganisms by microwave radiation with a natural amplitude and frequency-time structure compared with control and man-made radiation were preserved for Escherichia coli ATCC 25922, Enterococcus faecalis ATCC 19433, Enterococcus faecium ATCC 19434. The results of the conducted experimental studies are the basis for determining the applied aspects of the use of low-intensity microwave radiation for medical purposes.
