Abstract

Recently atmospheric pressure dielectric barrier discharge (APDBD) plays an important role in chemical, industrial and biological applications. It has been used for ozone synthesis, hydrogen production from natural gas, surface treatment including textile and polymer treatment, yeast and bacterial inactivation. The physics and mechanism of atmospheric pressure dielectric barrier discharge will be reviewed. Coaxial and planar DBD have been constructed for ozone production, textile treatment and yeast sterilization. Oxygen has been used as working gas for ozone production, while oxygen and argon will be used for yeast inactivation.

Key words: Microdischarge, DBD, ozone, yeast sterilization.
