The effects of low power microwaves at 1800 MHz and 2100 MHz on yeast cells growth

This experimental study evaluates the effects of low power microwave radiation on the growth rate of yeast Saccharomyces cerevisiae strains type II, exposed to the microwaves (MW) at the frequencies of 1800 MHz and 2100 MHz and the selected powers of -10 dBm, 0 dBm and 17 dBm using the Transverse Electro-Magnetic (TEM) cell. A comparative analysis of changes, induced by MW exposures at the particular frequencies and powers, on the growth rate of the irradiated yeast cells vs. control group was performed. The findings reveal that the selected MW exposures affected the rate of yeast cells growth. To evaluate the dependence of yeast cell growth rate on MW exposures' frequency and power, Chi-square Test was performed. The results showed that the MW radiations parameters (frequency and power) contribute independently to modulating effects observed in the yeast cells growth.
