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 hav. not induced any changes in further growth of bothStaphylococcus aureus(202) andStaphylococcus aureus(wild) cultures. Combined action:Deep freezing (up to -45℃) achiev.d 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.

Combined action of low temperature and magnetic field of different intensities on growth of some bacterial species <i>in v.tro</i>

作者： Oleksandr I. Raichenko v.adimir S. Mosienko v.adimir O. Shlyakhov.nko olena v. derev'yanko Yuriy v. Yanish olena v.

Growth dynamic of bacterial population after influence of magnetic field and cryoaction has been studied. In v.tro experiments were performed on Bacillus cereus, Staphylococcus aureus, and Lactobacillus delbrueckii cultures. The most significant result was obtained in experiments with Bacillus cereus. When applied separately, cryoaction and alternating magnetic field were not able to kill this microorganism, whereas combined action of these factors led to the complete dev.talization of bacterial culture.
