Abstract

In this study, we investigated the relationship between catalase activity and H2O2-
induced hormetic response in budding yeast S. cerevisiae. In general, our data suggest that: (i)
hydrogen peroxide induces hormesis in a concentration- and time-dependent manner; and (ii) the
effect of hydrogen peroxide on yeast colony growth positively correlates with the activity of
catalase that suggests the enzyme involvement in overall H2O2-induced stress response and
hormetic response in yeast.
