A specific effect of a weak alternating magnetic field (WAMF) with a frequency of 1–10 Hz, an intensity of 40–50 μT and an exposure of 20, 40 and 60 min on 3 strains of fungi of the genus Penicillium (P. funicullosum CNMN FD 11, P. piceum CNMN FD 21, P. verrucosum CNMN FD 19) was revealed, with the 3 strains exhibiting distinctly antimicrobial activity towards phytopathogens. WAMF has a positive effect on the catalase activity and biomass growth of P. piceum CNMN FD 21 and P. verrucosum CNMN FD 19 strains and an inhibitory effect on the catalase activity of strain P. funiculosum CNMN FD 11. An increase in the antifungal activity of strains P. funiculosum CNMN FD 11 and P. piceum CNMN FD 21 is observed, that is, the growth of pathogenic fungi is retarded significantly. Therefore, WAMF in the range 1–10 Hz improves the biosynthesis efficiency of biologically active substances of fungi of the genus Penicillium, determining their growth, enzymatic and antimicrobial activity. The result can be explained by the fact that the WAMF used has parameters of the so-called Schumann frequencies, which are vital for synchronizing the biological rhythms of living objects, including microorganisms.
