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 genusPenicillium(P. funicullosumCNMN FD 11,P. piceumCNMN FD 21,P. verrucosumCNMN 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 ofP. piceumCNMN FD 21andP. verrucosumCNMN FD 19strains and an inhibitory effect on the catalase activity of strainP. funiculosumCNMN FD 11. An increase in the antifungal activity of strainsP. funiculosumCNMN FD 11andP. piceumCNMN FD 21is 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 genusPenicillium, 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. |
