The aim of this work was to study low static external magnetic field effects 0-100 mT on the growth and development of E. coli bacteria. A large number of experimental points in this range, ongoing growth of bacteria in a magnetic field and the registration of changes in the physiological characteristics (CFU, growth rate) and biochemical parameters (ATP pool) guaranteed an obtainment reliable results. The colony-forming ability, growth rate constant and ATP pool in Escherichia coli bacteria are the magnetic-dependent characteristics of microorganism vital activity. They depend on the external static magnetic field and increase when its value lies in ranges 0-10 mT and 15-50 mT. The magnetic field rising from 50 to 100 mT leads to bacterial growth inhibition. All observed effects in bacteria E. coli are in good agreement with a theory of the enzymatic magnetosensitivity and determined by the spin dependent stages of intracellular enzymatic processes.
