Antioxidant system activation in littoral Baikalian amphipod Eulimnogammarus verrucosus

Mechanisms of antioxidant system activation in Baikalian endemic Eulimnogammarus verrucosus (Gerstf.) under oxidative stress was evaluated. For this study key antioxidant enzymes were used: peroxidase, catalase and glutathione S-transferase. Oxidative stress was induced by amphipods exposition in pro-oxidant humic substances solutions. It was showed that exposition of E. verrucosus in pro-oxidant humic substances solutions lead to significant changes in activities of peroxidase and catalase, however glutathione S-transferase was not changed.
