Long-term continuous treatment of non-sterile real hospital wastewater by Trametes versicolor

Abstract Background Hospital wastewater is commonly polluted with high loads of pharmaceutically active compounds, which pass through wastewater treatment plants (WWTPs) and end up in water bodies, posing ecological and health risks. White-rot fungal treatments can cope with the elimination of a wid...
