The indirect influence of the electromagnetic field on the growth of Bacillus subtilis


B.P. Shipunov, E.S. Yatsenko, B.N. Kagirov, A.V. Matsyura

The change in the number of microorganisms during cultivation on nutrient media prepared using water, which is influenced by an electromagnetic field of low power, is shown. Field-exposed water was used to prepare liquid and solid culture media for the cultivation of Bacillus subtilis bacteria. Field water treatment was carried out at several frequencies in the range of 30-230 MHz. In all cases, when using water exposed to field exposure, significant suppression of the vital activity of bacteria is observed. The discovered effect is explained based on the idea of a change in the hydration size of ions due to field exposure and their activity in membrane processes.
