Magnetic Fields and Magnetic Isotope 25Mg Effects on Biofilms Formation by Bacteria E. coli

Abstract

Abstract 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 E. coli compared to nonmagnetic magnesium isotopes 24.26Mg. Magnetic field effects in the range of 2–10 mT, recorded for all bacteria regardless of the magnesium-isotope enrichment of the nutrient medium, indicate the sensitivity of intracellular processes to weak magnetic fields.
