DC current, antibiotics, genetic mutations, voltage difference, sensitivityAbstract
Despite the many benefits and many uses of electric current, testing its ability to reduce bacterial growth has not received sufficient study and research. This study aims to test the ability of different voltage differences of continuous electric current to inhibit the growth of two types of bacteria, Staphylococcus aureus and Escherichia coli, and to cause genetic changes (mutations) in them by testing the change in the sensitivity of the bacteria to some types of antibiotics. The results showed a very limited effect of electric current at all times applied in the study on the growth rate of bacteria, as no change was observed in the growth rate of bacteria after growing them on the same type of medium used to grow them before exposing them to electric current. While the study showed a clear and varied effect of the voltage differences applied to the direct electric current on the sensitivity of bacteria to the antibiotics used in the study, which is an indication of the effect of electric current on the stability and constancy of the genetic material of bacteria and the increase in the rate of occurrence of genetic mutations in them.
