title: [The effects of the microwaves on E. coli cells depend on oxygen concentration and static magnetic field].
abstract: The effects of non-thermal microwaves (MW), 10(-4) and 10(-10) W/cm(2), on conformation of nucleoids in E. coli cells were analyzed by the method of anomalous viscosity time dependence (AVTD). MW exposure was performed at different values of static magnetic field and concentration of oxygen, 8-90 microT, and 2.3-7.8 mg/l, respectively. It was shown, that slight changes in both static magnetic field and oxygen concentration result in significant changes of MW effects up to their disappearance. It was established, that changes in static magnetic field affected significantly the time kinetics of the MW effects. The obtained data provide further evidence for strong dependence of the effects of non-thermal microwaves on physical parameters of exposure and physiological factors. These dependences should be taken into account in replication studies. The obtained results encourage further investigation of possible modulation of non-thermal MW effects by additional electromagnetic fields.
