Avdeeva E.I., Letuta U.G. THE MAGNETIC FIELDS INFLUENCE ON ESCHERICHIA COLI COLONY FORMING ABILITY IN MAGNESIUM ISOTOPES PRESENCESearch "primary receiver" of the external magnetic field in living organisms is intriguing scientific problem of biology, physics and chemistry. Magnetic isotope effects in biochemistry indicate the sensitivity of enzyme systems to magnetic moments of isotopes atomic nuclei. The purpose of this study is to detect the combined effects of the magnetic magnesium isotope, and an external static magnetic field on bacterial cell E. coli. The combined influence of weak magnetic fields and nuclear spin magnetic isotope ²⁵Mg on colony forming ability of E. coli cells was experimentally proved: in static external magnetic fields 0-25 mT the CFU number of bacteria enriched with magnesium ²⁵Mg was higher compared to the cells enriched with nonmagnetic isotopes of magnesium ^24,26Mg and natural magnesium. In the magnetic field of 76 mT the CFU number of bacteria enriched with magnetic isotope was the most. The detected magnetic field effects and magnetic isotope effects in the bacteria E. coli indicate the presence of magnetosensitive stages of enzymatic processes in living organisms. Key words: magnetic field, bacteria E. coli, colony forming ability, magnetic isotope, magnesium, enzymatic processes.
