| Popis: | Growth dynamic of bacterial population after in- fluence of magnetic field and cryoaction has been studied. In vitro experiments were perform- ed on Staphylococcus aureus (202), Staphylo- coccus aureus (wild) Micrococcus lysodeicti- cus and Pseudomonas aeruginosa. Cryotreat- ment: it has been demonstrated that both Sta- phylococcus aureus (202) and Staphylococcus aur- eus (wild) Micrococcus lysodeicticus and Pseu- domonas aeruginosa respond to the impact of cryoaction by pronounced growth retardation followed by rapid increase in biomass increment of cryo-resistant clones selected during the ex- periment. Magnetic influence: it has been shown that neither alternating magnetic field (MF) (in- duction 30 mT) nor constant MF (induction 52 mT) applied separately from deep freezing have not induced any changes in further growth of both Staphylococcus aureus (202) and Staphy- lococcus aureus (wild) cultures. Combined ac- tion: Deep freezing (up to −45˚C) achieved within 70 sec compared with the action of constant MF significantly stimulated (P < 0.05) growth of Sta- phylococcus aureus (202) and Staphylococcus aureus (202). Combined influence of cryoaction and alternating MF had no substantial effect on growth. |
