Most widely applied technologies wastewater treatment biological technologies are based on the selection of microbial communities dominated by bacteria (activated sludge).Wastewater treatment through Moving Bed Biofilm Bioreactors (MBBRs) has been widely used during the last years. The wastewater treatment with moving bio media consists in adding biofilm carriers (small cylindrical/ round/ plate shaped polyethylene/polypropylene/ polyurethane foam carrier elements) in aerated or anaerobic basins to support biofilm growth. The paper explored the functionalization of MBBRs (polyethylene support) structures in a Biotec FE 007 fermentor, with Cerioporus squamosus strain (a basidiomycete bracket fungus). Scanning Electron Microscopy and optical microscopy analysis were carried out pre and post microbial functionalization on the MBBRs in order to assess the colonization of the MBBRs structures and internalization of microbial biomass. The functionalized MBBRs will be further used in experiments of removal of recalcitrant compounds from cellulosic wastewaters.
