Abstract
We examined the viability of bacteria Escherichia coli and yeast Saccharomyces cerevisiae after their exposure to RF EMF (radio-frequency electromagnetic field). The frequency of the field was f=867 MHz, the maximal power was 10W (SAR = 2.0 W/kg) and the maximal duration of irradiation was 48 min. The exposure took place at laboratory temperature. We measured the viability using optical spectrophotometry of microbial culture in broth and we also used the CFU (colony forming units) counting on agar plate. We observed the decrease of viability in both bacteria and yeasts. In accordance with our previous experiments with ELF-EMF the RF EMF showed the saturation and the viability decrease of bacteria was bigger compared to the decrease in viability of yeasts.
Abstract (in Czech)
Sledovali jsme viabilitu bakterií a kvasinek po expozici 10 W, 867 Hz mikrovlnným polem za laboratorní teploty. SAR v místě dopadu byl 2 W/kg. Pozorovali jsme pokles viability pro oba sledované mikroorganismy.
