摘要：Atmospheric pressure dielectric barrier discharge (DBD) air plasma is a
   source of reactive species, such as OH·, H·, O·, H_2O_2, O_3, etc. The
   oxidative stress in Saccharomyces cerevisiae which was exposed to DBD
   air plasma at atmospheric pressure was studied. It was showed that the
   intracellular total antioxidant capability (T-AOC) and activity of
   glutathione reductase (GR) were activated, malondialdehyde (MDA) content
   increased in a treatment time-dependent manner, intracellular reactive
   oxygen species (ROS) content increased, and cell cycle arrested in G1
   phase significantly. It was proved that oxidative stress was induced in
   S. cerevisiae when the cells were exposed to DBD air plasma.
