Magnetosensitivity of E. coli Bacteria in the Presence of Zinc Isotopes

Abstract

The combined effect of the zinc magnetic isotope Zn and weak magnetic field 25-35 mT causes a 2-4-fold increase in the colony-forming ability of bacteria E. coli in comparison with the nonmagnetic isotopesZn. The effects of magnetic field in the range of 2.2-8 mT were detected for all bacteria regardless of the zinc-isotope enrichment of the media. This indicates the sensitivity of intracellular processes to weak magnetic fields. An increase in the ATP concentration in E. coli cells was only detected for the bacteria grown on the medium with the magnetic zinc isotope in the range of 2.2-4.2 mT. The obtained data confirm the existence of stages of intracellular enzymatic processes that are sensitive to magnetic fields and magnetic moments of atomic nuclei.

Biological effects of static magnetic fields and zinc isotopes on E. coli bacteria

“…In the third SMF range (60–70 mT), we found a slight increase in the intracellular concentration of ATP for bacteria cultured in the medium containing magnetic zinc isotope 67 Zn. A similar effect was observed by us earlier [Letuta and Berdinskiy, ; Letuta and Shailina, ] when studying the combined effect of the magnetic field of this range and the magnetic magnesium isotope 25 Mg. The majority of enzymatic reactions of ATP synthesis proceed through the formation of an ion–radical pair with the involvement of Mg 2+ [Buchachenko, ].…”

“…b, e, f). In this range the combined effects of SMF and magnetic magnesium isotope 25 Mg on the ATP pool in bacteria and the colony‐forming ability were previously found [Letuta and Berdinskiy, ; Letuta and Shailina, ]. Magnesium ions are effective participants of ion‐radical reactions of the ATP enzymatic synthesis [Buchachenko, ].…”

“…When bacteria grow in a nutrient medium containing magnetic magnesium isotope 25 Mg (that replaces other isotopes up to 95% [Shevchenko et al, ]), their growth rates and colony‐forming ability [Shevchenko et al, ; Letuta and Berdinskiy, ] increase. The joint effects of weak SMF and a magnetic isotope of magnesium, predicted in the theory of enzymatic magnetosensitivity, were registered in the range of 70–95 mT in number of colony‐forming units (CFUs), and in the intracellular ATP content of E. coli bacteria [Letuta and Berdinskiy, ; Letuta and Shailina, ]. There is other work confirming such magnetic sensitivity.…”

Possible Mechanisms of Biological Effects Observed in Living Systems during 2H/1H Isotope Fractionation and Deuterium Interactions with Other Biogenic Isotopes

“…Note: n—neutron; p—proton; D—deuterium; R-spin—resultant spin of individual isotopes or pair of isotopes with chemical bonds (as a sum of individual spins); k—integer. In the table, all references [27,29,41,84,85,86,87,88,89,90,91,92,93] confirm the new hypothesis and arising resonance in living and natural systems only under certain isotopes. Note: I, III, and VII—pairs of isotopes with chemical bonds and individual isotopes that must have no isotopic resonance; II—there is no isotopic resonance for: Nn − Np = −1; IV—there is no isotopic resonance for: Nn − Np = 0; V and IX—pairs of isotopes with chemical bonds and individual isotopes that have some isotopic resonance; VI—there is some isotopic resonance for: Nn − Np = 1; VIII—there is no isotopic resonance for: Nn − Np = 2, and Nn − Np = 2k; X—there is some isotopic resonance for: Nn − Np = 2k + 1; N—number.…”
