Heavy metal pollution is a matter of concern in industrialised countries. Contrary to organic pollutants, heavy metals are not metabolically degraded. This fact has two main consequences: its bioremediation requires another strategy and heavy metals can be indefinitely recycled. Yeast cells of Saccharomyces cerevisiae are produced at high amounts as a by-product of brewing industry constituting a cheap raw mate...

In the present work, the influence of the competitive effect of inorganic ligands (carbonates, chlorides, fluorides, phosphates, nitrates and sulphates), which can be present in real multi-metal electroplating effluents, on the biosorption of chromium, copper, nickel and zinc ions by yeast cells of Saccharomyces cerevisiae was rationally examined. Additionally, chemical speciation studies allowed optimizing the...
In this work, the suitability of live and inactivated cells of a brewing yeast strain of Saccharomyces cerevisiae NCYC1364 in the removal of Cu2+, Ni2+ and Zn2+ from solution was compared. Kinetics studies showed that 30 minutes of the contact of live or dead cells with all the metals were enough to occur the maximum removal, except for live cells with Cu2+, where the equilibrium was attained after 60 minutes. ...
