Abstract
Stanice algi imaju izvanrednu sposobnost unošenja i nakupljanja teških metala iz vanjskog okoliša. Visoke koncentracije metala, uključujući one esencijalne za rast i metabolizam, toksično djeluju na metabolički sustav algi. Pokretljivost stanica, koncentracije klorofila a i b te karotenoida i nakupljanje prolina, kao ključni toksikološki parametri, proučavani su tijekom 14 dana uzgoja slatkovodnog flagelata Euglena gracilis pri različitim koncentracijama soli teških metala Al2+ i Cd2+ (0.5, 1.0 i 2.0 mM). Stanice E. gracilis bolje podnose izloţenost Al2+ ionima (bolja pokretljivost i bolja sposobnost vršenja fotosinteze). Uočena je značajna osjetljivost na Cd2+ što se očituje i po fotosintetskim pigmentima, pokretljivosti i nakupljanju prolina. Rezultati daju korisne i vaţne informacije o funkcionalnoj vrijednosti E. gracilis u bioremedijacijskim programima.
Abstract (english)
Algal cells have a remarkable ability to uptake and accumulate heavy metals from their external environment. High concentrations of metals, including those essential for growth and metabolism, exert toxic effects on metabolic system of algae. The effects of different concentrations of Al2+ and Cd2+ (0.5, 1.0 and 2.0 mM) on the freshwater flagellate Euglena gracilis were studied upon 14 days of growth using cell mobility, contents of chlorophyll a and b, carotenoids and proline accumulation as end toxicology points. E. gracilis cells showed improved heavy metal tolerance to Al2+ ions (greater mobility and better photosynthetic capacity). Photosynthetic pigments, mobility and proline accumulation were found to be greatly sensitive to Cd2+. These results provide useful and important information about functional value of E. gracilis for bioremediation programs.
