The biofilm formation by bacteria E. coli is a magnetosensitive process. The combined effects of a magnetic magnesium isotope 25Mg and a static magnetic field in the range of 20-35 mT stimulate biofilm formation by bacteria E. coli compared to non-magnetic magnesium isotopes 24,26Mg. Magnetic field effects in the range of 2-10 mT, registered for all bacteria regardless of magnesium-isotope enrichment of nutrient medium, indicate the sensitivity of intracellular processes to weak magnetic fields.
