Investigation of kinetics of zinc biosorption by Saccharomyces cerevisiae cells.


The highest amount of zinc (approximately 90%) is bound after 3 h of contact at low initial (total) concentrations of zinc in yeast broth, 2.0-16.0 g/l at 10-30 degrees C. The equilibrium between bound and free zinc ions is established after 6 h of contact time, independently on total zinc concentration in yeast milk. No bigger changes of content of zinc… (More)
