Plasma, a unique state of matter with properties similar to those of ionized gas, is an innovative sterilization method characterized by its low toxicity and operation at room temperature. However, the study of plasma generations through the microbial inactivation in seawater containing the salt is not known and efficient yet. Thus, plasma device generated by a dielectric barrier discharge system was applied to inactivate pathogenic bacteria containing Halobacterium cells that live in seawater. This cleaning system against microbial contamination was investigated the sterilization efficiency by the operation of the plasma device in seawater with various concentrations of sodium chloride, in which the relative sterilization ratios via plasma exposure time. There are some errors by bubbles generated in the machine operation; however, the sterilization effect of near 80% was obtained within 20 min in all experiments. These results support the use of plasma for the aquacultural industry for removal of organic contaminants in seawater. It is anticipated that the plasma sterilization has a potential to improve the productivity of sea-food industry and to keep healthy environment in seawater.
