Species specificity and reaction of bacteria to a 50 GHz magnetic field

The growth of cultures of bacteria with different lipid content of cell membranes in response to a 40 min exposure to alternating magnetic field of 50 Hz, 18 mT was studied. Three important phenomena were revealed. A species specificity of responses of bacteria to the magnetic field, including both inhibition and activation, was observed. The changes in the kinetics of growth of bacterial culture correlate with the type of membrane lipid complex. The information on the exposure to magnetic field is memorized by the previously exposed distilled water, which makes itself evident in responses much more intensive than the responses of the same cultures exposed immediately in the culture medium.
