Effects of the magnetic field and zinc isotopes on the colony forming ability and elemental composition of E-coli bacterial cells

The combined effects of external weak magnetic fields and nuclear spins of the magnetic isotope Zn-67 on vital functions of E. coli bacterial cells were proved experimentally. Metabolism of the major elements in E. coli depends on the intensity of the external static magnetic field and zinc isotopes contained in the nutrient medium. The combined effects of the external static magnetic field and zinc magnetic isotope Zn-67 are observed in a change in the number of colony-forming units of E. coli bacteria in a range of 25-35 mT and in the content of Na, Ca and Mg in a range of 65-80 mT. The obtained data confirm magnetic sensitivity of intracellular enzymatic processes to the static magnetic field and magnetic moments of atomic nuclei.
