The basic properties of soils in major physiographic units of the area were examined. The content of several heavy metals (Cu, Zn, Mn, Pb, Cd, Co) in soils and selected vascular plants were determined, also. The relationship between the content of metals in plants and the content of metals in soils was determined. The content of metals in both soils and plants had a particular order, although not...
Lipoxygenase was localized in the primary leaves of Phaseolus coccineus (L.), seedlings treated with 25 µM Cd and in control plants using the immunogold method. The enzyme was localized mainly in the peripheral parts of protoplast of control plant cells. It was found in the cell wall, along the ER elements, at plastid lamellae and inside the mitochondria. In Cd-treated seedlings the elements of parenchyma...
In Escherichia coli, heterologous production of Schizosaccharomyces pombe phytochelatin synthase (PCS) along with overproduction of E. coli serine acetyltransferase (SAT) and gamma-glutamylcysteine synthase (gammaECS) was achieved and resulted in the accumulation of phytochelatins in bacterial cells. Overproduction of either gammaECS alone or simultaneous production of all three proteins in bacterial...
The aim of the research was to estimate efficiency of monoaecian fibrous hemp (Cannabis sativa L., "Benico" variety) for phytoextracting heavy metals from soil-sludge substrate during anaerobic sewage sludge treatment at non-industrial sites. Hemp is known to be an efficient lead, chromium and cadmium phytoextractor from soils, though these heavy metals cannot be found among plants nutrients...
Introduction. Single intraperitoneal injections of sublethal doses of cadmium (10 µg Cd·kg-1 body weight) and nickel (60 µg Cd·kg-1 body weight) were administered to carp, Cyprinus carpio L., to determine detoxification potential of the fish affected after transfer to a clean milieu, as revealed by haematological parameters. Observation of haematological parameters allows the most rapid detection...
