Several studies have demonstrated that exposure to various electromagnetic fields (EMFs), including those in the 5G frequency range, can stimulate fungal growth under specific conditions.
For instance, 2 GHz RF-EMF enhanced enzyme production and secretion in Aspergillus oryzae by increasing protein levels and mRNA expression.
Similarly, 900 MHz EMF boosted mycelial growth and pathogenicity in entomopathogenic fungi like Cordyceps fumosorosea.
Extremely low-frequency EMFs increased growth rate, conidia production, and cell wall integrity in Magnaporthe oryzae via upregulated genes and ROS levels.
Other research showed 18 GHz exposure promoting cell growth in various fungi, 60 Hz magnetic fields stimulating colony expansion in Aspergillus niger, and low-frequency EMFs combined with biostimulators accelerating fungal proliferation.
A 2019 review further noted growth increases in fungi at 40–50 GHz in most in vivo studies, highlighting variability by frequency and species.
