Biosorption of zinc ions by living and dried biomass of the green alga Scenedesmus quadricauda Zoltán Novák Mihály Jánószky 2, Sándor Alex Nagy ', István Bácsi 1 Abstract: Environmental pollution has been become global problem in recent years by human activities, which can be harmful directly to the elements of biosphere and could have indirect effects on living organisms. Heavy metals are one of the most dangerous materials among chemical contaminants. When they are released to the environment, they can cause serious damage to ecosystems. The genera Scenedesmus and the species Scenedesmus quadricauda is common, ubiquist organisms. They can be easily cultured and maintained in laboratory and they are widely used for biotechnological processes. Scenedesmus quadricauda can tolerate zinc in the range of 2,5-15 mg/L concentration, so the species can be characterized with moderate zinc tolerance. The growth rates of the cultures were reduced by the increasing zinc contrentations. Maximal zinc removal was observed in the 5mg/L zinc-treated culture (87,6% of the added zinc was removed) and greater part of bound zinc was extracellular (77-89%). Dried biomass could bind significant amount of zinc (56-58%), however zinc binding of the same amount of living biomass was significantly higher. Keywords: Scenedesmus quadricauda, living biomass, dried biomass, zinc removal.
