Biological effects in Pseudomonas species by the non-thermal atmospheric pressure plasma conditions

Atmospheric pressure plasma is a great technique in plasma science, which was implemented in our research. To study the biological changes in two pseudomonas strains in terms; type of plasma, exposure time and power discharge in the plasma. Scanning electron microscope (SEM) was used to determine the biological changes in two pseudomonas bacterial strains before and after plasma treatment with different time periods, and also recorded the biodegradation activity of two pseudomonas based on the survival bacterial growth rates from the untreated and plasma treated samples. Our results indicated that neutral gas and the atmospheric plasma radiation play a vitol role in the biological changes and also deactivate the bacterial cells such as Pseudomonas putida; Pseudomonas fluorescens. Experimental results proved that, atmospheric argon plasma most effective on pseudomonas bacterial samples and alter the biodegradation activities.
