Sterilization in Plaxy Glass tube by microwave

Summary form only given. Microwave plasma was built to produce plasma in an axial direction. Plasma was initiated in a Plaxy Glass made vacuum tube using a 2.45 GHz commercial magnetron and the system was driven by a 14 A DC current passing through a 16 cm inner diameter toroid. Measurements with a Langmuir probe and ICCD for optical spectrometry were used to characterize internal parameters like electron density, electron temperature and different properties of the heavy particles. This study presents the effect of the system on the bacteria. They are gram positive and gram negative bacteria that refers to structure of the cell wall. The sterilization efficacy of microwave plasma was found to be over 99.5% in Staphylococcus aureus, Staphylococcus epider-midis, Bacillus subtilis (vegetative cell), Bacillus cereus (vegetative cell), Klebsiella pneumonia and Escherichia coli.
