Annotation:  In the article the results of the investigation of the influence of the earthing on the microbial growth and propagation are represented. On this problem experiments with Escherichia coli, Enterococcus faecalis, Proteus mirabilis and Salmonella typhimurium were performed in the earthed Petri dishes and test tubes. The earthing was produced by using the copper foil and the electrodes of stainless steel (grade AISI 304). Determination of the concentration of microorganisms was carried out by using the instrument “Densi-La-Meter” (fabricator: Erba Lachema, Czechia) for determining the turbidity of the bacterial suspensions. It established a stimulating effect of the earthing on the growth rate of microbial populations by payment of the local deficiency of the electronic background in nutrient media. The results testify that the stability of the intensive reproduction of the microorganisms is coordinated by the electrical field of the Earth. The earthing counteracts the electrical instability and declines the deficiency of electrons, which significantly affects on the growth and development of microorganisms.
