Abstract: The results obtained in the frame of some experiments focused on the bacteria response to external constraints of (electro) magnetic nature are presented in the next. A. The cell density dynamics was studied for S. aureus cultivated in the presence of magnetic nanoparticles or under microwave exposure. It was found that this germ exhibit magneto- sensitivity to the gradual increase of magnetic nanoparticle concentration as well as of the electromagnetic exposure time. The response of B. megaterium to magnetic nanoparticle loading was also evidenced and discussed. B. The bacteria inactivation under the impact of electric discharge under atmospheric conditions was evidenced. High level of bacteria killing was evidenced for several cm distance between the discharge electrodes for some collection or wild strains of: S. aureus, B. subtilis, S. lutea, B. cereus.
