Abstract: Growth dynamic of bacterial population after influence of magnetic field and cryoaction has been studied.In vitroexperiments were performed onStaphylococcus aureus(202),Staphylococcus aureus (wild) Micrococcus lysodeicticusandPseudomonas aeruginosa.Cryotreatment: it has been demonstrated that bothStaphylococcus aureus(202) 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 aureus(202) andStaphylococcus aureus(wild) 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 aureus(202) andStaphylococcus aureus(202). Combined influence of cryoaction and alternating MF had no substantial effect on growth.
