The biological effects of a 25 Mg nuclear spin and weak magnetic fields have been found and studied by using bacterial cells of Escherichia coli (E. coli) grown on standard M9 nutrient media with different isotopes of magnesium: 24 Mg, 25 Mg, 26 Mg, and a natural mixture of Mg isotopes. Among these isotopes only 25 Mg has a nuclear spin I = 5/2 and nuclear(More)
Effects of synergism and antagonism of antibacterial drugs and magnetic isotope of magnesium 25Mg on antibiotic resistance of bacteria E. coli were discovered. Fourteen antibiotics from seven different groups were tested. The increase in antibiotic resistance in the presence of the ion 25Mg2+ was discovered in E. coli cells incubated with(More)
Primary biological magnetoreceptors in living organisms is one of the main research problems in magnetobiology. Intracellular enzymatic reactions accompanied by electron transfer have been shown to be receptors of magnetic fields, and spin-dependent ion-radical processes can be a universal mechanism of biological magnetosensitivity. Magnetic interactions in(More)
The ATP pool in Escherichia coli is a magnetic-dependent characteristic of microorganism vital activity. It depends on the values of the external static magnetic field and the existence of magnetic moment of magnesium isotopes nuclei added to the growth nutrient medium. The combined effects of the magnetic field 70–95 mT and magnesium magnetic isotope 25Mg(More)
