Growth dynamic of bacterial population after influence of magnetic field and cryoaction has been studied.In vitroexperiments were performed onStaphylococcus aureus202,Staphylococcus aureus wild Micrococcus lysodeicticusandPseudomonas aeruginosa.Cryotreatment: it has been demonstrated that bothStaphylococcus aureus202 andStaphylococcus aureus wild Micrococcus lysodeicticusandPseudomonas aeruginosarespond to the impact of cryoaction by pronounced growth retardation followed by rapid increase in biomass increment of cryo-resistant clones selected during the experiment. Magnetic influence: it has been shown that neither alternating magnetic field MF induction 30 mT nor constant MF induction 52 mT applied separately from deep freezing have not induced any changes in further growth of bothStaphylococcus aureus202 andStaphylococcus aureuswild cultures. Combined action:Deep freezing up to -45℃ achieved within 70 sec compared with the action of constant MF significantly stimulated P < 0.05 growth ofStaphylococcus aureus202 andStaphylococcus aureus202. Combined influence of cryoaction and alternating MF had no substantial effect on growth.
