“…In our experiment, only low concentrations of PCBs were used (50 and 100 µg kg -1 of each congener), while in the mentioned studies the concentration of PCBs was up to 3000 µg kg -1 . It was confirmed that the efficiency of PCB degradation increased with a lower chlorination grade (Kubátová et al 1996, 2001, Koeller 1999. The chlorination grade affected the translocation of PCBs into fruit bodies as well (Moeder et al 2005).…”

“…Phanerochaete chrysosporium (a model fungus in studies of PCB degradation), Trametes versicolor, Lentinula edodes and Pleurotus ostreatus have proven to be effective in the degradation of PCBs. Some of them were reported to degrade even more than 70% of PCBs depending on the initial concentration of PCBs, time of incubation and the fungal species (Šašek et al 1993, Kubátová et al 2001, Ruiz-Aguilar et al 2002.…”

White rot fungi (WRF) are known to have the ability to degrade organic pollutants with a structure similar to lignin. Because of this, the degradation of polychlorinated biphenyls (PCBs) congeners no. 28, 52, 101, 138, 153 and 180 by substrate before fruiting (substrate) and/or after fruiting (SMS) from cultivated mushrooms Pleurotus ostreatus, Lentinula edodes and Agaricus bisporus was examined. The experiment was carried out in four replications for each treatment using a mixture of substrate/SMS and sandy soil with PCBs at a concentration of each congener at 50 and 100 µg kg -1 soil DW. The results indicate that degradation was dependent on substrate/SMS addition, the concentration of PCBs and time of incubation. The efficiency of PCB degradation was generally reduced with the number of chlorine atoms in the structure of congeners: 28, 52, 101, 138, 153 or 180. In all combinations, degradation increased with incubation time. Degradation by SMS was lower in comparison to degradation by a substrate of the same mushroom. The degree of degradation of a single PCB after 12 weeks of incubation for A. bisporus ranged from 31.32 ± 1.52 to 83.91 ± 1.07%, while for P. ostreatus it was between 37.88 ± 2.54 and 78.29 ± 1.41%; for L. edodes it ranged from 17.38 ± 1.06 to 75.30 ± 1.46%. The best average degradation was confirmed for 20% SMS of A. bisporus at 50 µg kg -1 PCB.Ke y wor d s: congener, mycoremediation, spent mushroom substrate, white rot fungi
