On the Relationship between the Z-Component of the Geomagnetic Field and the Biological Activity of an Aqueous Bacterial Suspension

Abstract

Changes in Escherichia coli and Staphylococcus aureus reproduction were experimentally studied upon exposure of bacterial suspensions or the solvent (water) to a rectified electromagnetic field of a low frequency (4 Hz) and low intensity (~5.1–6 T) with various orientations of its vector with respect to the Z axis of the geomagnetic field. An increase in the total Z component of the field that influenced bacteria was associated with an accelerated formation of bacterial colonies, while a decrease in the component inhibited bacterial colony formation.
