The influence of basic physical factors caused by magnetite nanoparticles (constant magnetic field and sorption) on microorganisms by
examining the reactions of the intensity of free radical lipid peroxidation (FRLP) and bacteriostatic action was studied. It was well
established that the magnetite nanoparticles caused unequal reaction in intensity of FRLP on different groups of microorganisms. It was
determined that the most significant factor that influenced the ultimate indicator of the intensity of luminescence on Candida albicans,
Escherichia coli and Pseudomonas aeruginosa was constant magnetic field which induced by nanoparticles. On the contrary, sorption was
the most significant factor on Staphylococcus aureus. It was found that the rate of consumption of free radicals lipid reduced reliably on
all microorganisms after their processing by magnetite nanoparticles. The results of microbiological studies of Escherichia coli, Klebsiella
pneumoniae and Staphylococcus aureus showed that bacteriostatic effect was detected after exposure by magnetite nanoparticles. Visually,
it was detected by decreasing the number of colonies on the nutritious medium in comparison with the control. It revealed an interesting fact
that saline NaCl, which had previously been processed by magnetite nanoparticles also significantly, had a marked bacteriostatic effect on
the studied microorganisms. This effect could be explained by mechanism of change in the polarization structure water of microorganisms
by magnetite nanoparticles. It was discovered that degree of expression of bacteriostatic action which induced by magnetite nanoparticles
had correlation with marks of reactions intensity of FRLP. Maximum bacteriostatic effect on Staphylococcus aureus was expressed in
second variant application of magnetite nanoparticles where mechanism of sorption was more significant than action of the magnetic field.
On the contrary, maximum bacteriostatic effect on Escherichia coli and Klebsiella pneumoniae was revealed in third variant, where time
exposition of contact with microorganism’s nanoparticles and, consequently, action of a constant magnetic field was determinative.
