In the biosorption of heavy metals with
Phanerochaete chrysosporium the order of affinity for
competitive conditions was Cu (II)>Pb (II)>Cd (II) [28].
Competitive biosorption experiments were performed
with Cd and Pb together with Cu and the biosorption
capacities of the yeast biomass for all metal ions were
found to be lower than in non-competitive conditions
[29].
