Изменения активности ферментов антиоксидантной системы при воздействии повышенной солености на палеарктический вид амфипод Gammarus lacustris Sars

Abstract

The aim of the present study was to evaluate activity of antioxidant en­zymes (peroxidase, catalase, glutathione S-transferase) in Palearctic amphipod species Gammarus lacustris Sars under increased salinity. Activity of peroxidase and catalase was stable under combined influence of increased salinity and temperature. Opposite to this, activity of glutathione S-transferase decreased in the same conditions. Prob­ably, here we demonstrated possible participation of antioxidant enzymes in adaptation mechanisms to environmental changes in widespread amphipods G. lacustris.
