Abstract

Removal of recalcitrant environmental pollutants is a major problem. In particular, there are no methods other than incineration or landfilling for the removal of organochlorine compounds like PCBs, dioxins and chlorinated pesticides. These were widely used in the past, but now are either found as contaminants in the environment or stored in large quantities where they constitute a big risk. The search for alternatives to solve this issue sets a challenge for environmental sustainability. Biotransformation by basidiomycetes to remediate contaminated sites is an unexplored path in the region, despite the development these technologies have in European countries. In order to select fungi capable of degrading persistent compounds into harmless ones, a screening of native basidiomycetes isolated from natural sources was performed. The insecticide endosulfan was used as model molecule; endosulfan was banned in the European Union in 2007 and in our country in 2011. It was widely used in soybean cultivation and there are tons stored waiting its destruction. Specific methodologies were developed for evaluation of the biotransformation and the results were followed by gC-ECD. One of the fungi studied, Bjerkandera adusta, was able to degrade 87% of the added endosulfan after 27 days of incubation.
