“…All these factors enhance the effect of distance on killing gram-negative bacteria and destruction of the cell membrane, resulting in the release of cytoplasm and cell death. This can be explained, that when the voltages are low (less than the breakdown voltages), the energy processed to the molecules by the electric field is low and is incapable of producing elementary and secondary ionizations to molecules, and by increasing voltages, begins the initial ionization of the molecules and register low values for the current [19].…”

In this research, a type of gram negative bacteria was exposed to non-thermal plasma at a distance of (2 and 3 cm) from the plasma flow nozzle, with the use of an alternating power supply (5KHz), where exposure was made at two different voltages (4.9 and 8 kV). A negative gram of Pseudomonas aeruginosa bacteria was isolated and exposed to non-thermal plasma at different flow rates of argon gas whose value ranged from (1-5) liters/minute. The results showed that bacterial killing rate is directly proportional to distance while exposing the samples to non-thermal plasma, and the best factors by which a complete killing rate was obtained were at a distance of 2 cm with a voltage of 8 kV and a gas flow rate of 5 liters/min, while complete killing of bacteria was not achieved at a distance of 3 cm where the percentage was 95% at the same argon gas flow rate.
