Popis:	A wide study has been conducted on the fate of xenobiotics in the environment and more particularly on the biodegradation of these compounds. The selection of fungal strains able to degrade pentachloronitrobenzene (PCNB) has been performed. Of the collection of strains in our laboratory 1060 were incubated with PCNB (100 mg/l) for 5 days in liquid synthetic medium. The production of extracellular phenoloxidases was examined by using ten different reagents. We found that only 3% of the strains were able to degrade PCNB by over 70%. The most performant groups were Mucedinaceeae and Zygomycetes. No correlation was found between the production of extracellular phenoloxidases and the biodegradative capability of individual strains. A detailed study of PCNB metabolism by selected strains is in progress.
