We investigated the potential use of the antioxidant defense enzymes in
freshwater mussel (Unio pictorum) as biomarkers of oxidative stress. The
enzymatic activities of superoxide dismutase (SOD, EC 1.15.1.1) and catalase
(CAT, EC 1.11.1.6), total protein concentration in addition to protein and
SOD electrophoretic profiles were examined in the digestive gland and gills
of the freshwater bivalve Unio pictorum at two localities on the River Sava.
The differences between SOD and CAT activities in examined tissues of
freshwater bivalve Unio pictorum reflect dissimilar metabolic and
antioxidative activities and this can be the result of both tissue or
locality specificities and diverse ecophysiological influences on the
organism.
