The aim of this study is investigate the role of reserve carbohydrates, trehalose and glycogen in DEM
(Diethyl Maleate) induced oxidative stress in yeast Saccharomyces cerevisiae Y6210. Trehalose and glycogen
accumulated in Saccharomyces cerevisiae, when growth conditions deteriorate. Yeast cells were subjected to
oxidative stress for different time periods (0, 30, 60 and 120 min) to evaluate the role of trehalose, glycogen
and trehalase. There was no change in the level of trehalose while the content of glycogen increased during the
oxidative stress. The time dependent modulation in the activities of trehalase and invertase was observed under
oxidative stress. It has been suggested that glycogen serving as a protectant during oxidative stress not
trehalose.
Key words: Diethyl maleate, glycogen, invertase, oxidative stress, trehalase, trehalose,
