The feasibility of the operation of a fluidized bed reactor for the removal of estrogens by immobilized laccase was investigated in order to improve the degradation yields and enzyme stability previously obtained with packed bed reactors. High removal levels (between 76 and 90%) and significantly prolonged stability of the biocatalyst over 16 days were attained. In parallel, a decrease up to 90% in the estrogenic activity of the effluent was measured. Thus, the technology presented seems a promising tool to increase the applicability of laccases in bioremediation processes. Copyright © 2012 Elsevier B.V. All rights reserved.
