    Biosorption of Nickel by Yeasts in an Osmotically Unsuitable Environment

  • Original language description

    The tolerance, sorption of nickel(II) ions, and changes in the production and composition of exopolymers of eight yeast strains grown under nickel presence with/without NaCl were studied. Strains of Pichia anomala and Candida maltosa known as the most resistant yeasts against nickel tolerated up to 3 mm Ni2+. NaCl addition decreased both the resistance of the yeast strains toward nickel ions and the sorption of metal ions into cells. All yeasts absorbed nickel predominantly into exopolymers (glycoproteins) and on the surface of cells. However, while the amount of polysaccharide moieties of exoglycoproteins of most of the resistant yeasts was induced by stress conditions, the ratio polysaccharide/protein in the exopolymers remained unchanged in the sensitive species Cystofilobasidium. The exopolymer composition might play a key role in yeast adaptation to stress conditions caused by heavy metal ions.

    Biosorpce niklu kvasinkami v osmoticky nevhodném prostředí

  • Czech description

    Byla studována tolerance osmi kvasinkových kmenů vůči niklu a změny v produkci extracelulárních polymerů v prostředí proměnného osmotického tlaku roztoku NaCl. Kmeny Pichia anomala a Candida maltosa jsou velmi rezistentní vůči iontům niklu až do 3 mM Ni2+. Přídavek NaCl zvyšuje rezistenci vůči iontům niklu a sorpci kovu do nitra buňky. Všechny použité kmeny prioritně sorbovaly nikl na své extracelulární polymery (glykoproteiny) nebo na povrch buněk. Složení extracelulárních polymerů hraje důležitou rolipři adaptaci kvasinek na stresové podmínky v přítomnosti iontů těžkých kovů.
