The Effects of Electromagnetic Fields with a Frequency of 2450 MHz on E. coli Bacteria

Abstract

This study analyzes the effects of the devices that work at the frequency of 2450 MHz and that release electromagnetic waves on the growth of bacteria. E. Coli bacterial cells are used in this experiment. The bacterial cult is divided into two groups under sterilized conditions. For both groups, the temperature is held constant at 37 Co while the heating effect of the devices working at the frequency of 2450 MHz is minimized. Then, the bacterial cells in the experimental group are exposed to the electromagnetic waves released by the devices working at the frequency of 2450 MHz while the control group is incubated for 8 hours without any exposure to electromagnetic waves. At each hour, samples from the E. Coli bacteria that are exposed to electromagnetic waves and from the control group. After measuring the optical density of the samples, it is found that the electromagnetic waves released by the devices working at the frequency of 2450 MHz have negative effects on the growth of bacteria. So, the effects of the electromagnetic waves released by the devices working at the frequency of 2450 MHz on the growth of the bacteria might be thermal or stress-related. However, there is a need for further physiologic and morphologic studies on this issue. The studies on this issue should be conducted for the public health.
