Resumen
This chapter summarizes the novel approaches employed for the
removal of emerging pollutants from sludge by means of fungal processes. The
first part of the chapter introduces the potential application of fungi in bioremedia tion, which sets the background for the next chapters of the book. This includes a
description of the fungal enzymatic systems usually involved in the oxidation of
pollutants, as well as a brief review of the wide range of contaminants so far known
to be degraded by fungi. The second half of the chapter presents the state of the art
in application of fungi to remove emerging pollutants in sludge which, due to its
novelty, is reduced to only a few reports performed in solid-phase and slurry
reactors with Trametes versicolor, mostly under sterile conditions but with
references of removal of pharmaceuticals under non-sterile conditions. Data avail able include several emerging pollutants which were grouped according to their
function or activity: pharmaceutical compounds (26 drugs), brominated flame
retardants (6), UV filters (7) and estrogens (3). Finally some considerations about
the residual toxicity of the processes are discussed.
