This work describes the optimization and characterization of enzymatic membranes assessed for the degradation of two phenolic compounds (2,6-dimethoxyphenol (DMP) and guaiacol) by laccases from Trametes versicolor using the flow-through membrane reactor concept. The results obtained show that the optimized membrane is very reactive, although polymer formation during DMP degradation causes membrane plugging that subsequently decreases permeate flow. Nevertheless, the enzymatic membrane can be of interest for much diluted substrates or for relatively un-reactive reaction intermediates that do not cause significant membrane plugging by polymer formation. This work opens new perspectives for the application of enzymatic membranes for the removal of refractory pollutants containing phenolic groups. (c) 2012 Elsevier B.V. All rights reserved.
