To elucidate the mechanism of the electrochemical killing, the global gene expression of synchronously cultured Saccharomyces cerevisiae exposed to electrochemical stimulus was analyzed using DNA microarray. By applying a potential of 1.0 V vs. saturated calomel electrode (SCE), oxidative stress related genes were expressed after only 5 minutes. The gene for cta1 exhibited the highest expression level, while ROS gradually accumulated inside the cells. Genes for signal transduction which may be related to cellular apoptosis were also seen expressed.
