Removal of heavy metals using a brewer’s yeast strain of Saccharomyces cerevisi...
Machado, Manuela D.; Santos, Mónica S. F.; Gouveia, Cláudia; Soares, Helena M. V. M.; Soares, Eduardo V.In this work, a brewer’s yeast strain was used to remove heavy metals from a synthetic effluent. The solid–liquid separation process was carried out using the flocculation ability of the strain. The yeast strain was able to sediment in the presence of Cu2+, Ni2+, Zn2+, Cd2+ and Cr3+, which evidences that the flocculation can be used as a cheap and natural separation process for an enlarged range of industrial e...
