Undergraduate Research: Plasma Sterilization
This report details the test results and brief summary of my experiences participating in undergraduate research as a member of the Applied Physics Research Group, led by Dr. Subrata Roy, studying the sterilizing effects of Dielectric Barrier Discharge Plasma on yeast. This undergraduate research project provided a valuable vehicle for experiencing advanced research methodology and data collect...
متن کاملSurface Decontamination by Dielectric Barrier Discharge Plasma
Background: Dielectric barrier discharge (DBD), a source of non-thermal plasma, is used in surface decontamination. Objective: To study the effect of DBD plasma treatment, we evaluated the effect of plasma exposure time on inactivation of Bacillus subtilis. Results: Applying the DBD plasma to the culture of B. subtilis caused complete sterilization of the surface without any thermal effects. In...
متن کاملEffect of Dielectric and Liquid on Plasma Sterilization Using Dielectric Barrier Discharge Plasma
Plasma sterilization offers a faster, less toxic and versatile alternative to conventional sterilization methods. Using a relatively small, low temperature, atmospheric, dielectric barrier discharge surface plasma generator, we achieved ≥ 6 log reduction in concentration of vegetative bacterial and yeast cells within 4 minutes and ≥ 6 log reduction of Geobacillus stearothermophilus spores withi...
متن کاملPlasma technology for sterilization of food packaging material
An efficient inactivation of surface contaminants like micro organisms or toxins is a requirement for the manufacturing of safe and high-quality products in food industry. In a research project funded by the BMBF (FKZ 13N7609) the so called cascaded dielectric barrier discharge was developed (CDBD). This patented system is a further development of a dielectric barrier discharge which combines g...
متن کاملFlame Stabilization Using a Pulsed Plasma Discharge in Subsonic Flow
Stable combustion in a harsh environment, such as lean fuel concentration and/or low temperature conditions, is attractive because of its low emissions. However, such flames suffer from lack of stability. In our research, an AC plasma discharge is applied to a lifted jet flame to increase the stability of the flame. Two types of discharges are utilized for this experiment. First, a single elect...
