The influence of electromagnet icirradiation and gas composition of cultivation conditions on the ability of staphylococci and corynebacteria to biofilm formation
Theoretical and experimental substantiation of millimeter waves in different frequency bands and microaerophilic cultivation conditions influence on the formation of staphylococci and corynebacteria subpopulations with low and high ability to form biofilms is presented in the article. It was experimentally proved that electromagnetic waves in the frequency range of 42.2 GHz were able to stimulate Staphylococcus aureus test-strains biofilms formation and inhibited biofilms formation of pathogenic corynebacteria. It was shown the significant increase of corynebacteria test-cultures biofilm formation and the tendency to increasing of the properties in some strains of S. aureus under the influence of irradiation in 61.0 GHz frequency range. For microaerophilic cultivation conditions ability of Staphylococcus aureus to the formation of biofilms increased, but for pathogenic corynebacteria it was unchanged.
