“…Particularly, white rot fungi (WRF) exhibit features that make them excellent candidates for remediation technology (Čvančarová et al . 2012; Vishwakarma 2019). These ligninolytic fungi with their extracellular, low substrate specificity enzymes have been proved capable of degrading a wide range of organic pollutants, including PCBs (Tomasini and León‐Santiesteban 2019; Vishwakarma 2019).…”

“…2012; Vishwakarma 2019). These ligninolytic fungi with their extracellular, low substrate specificity enzymes have been proved capable of degrading a wide range of organic pollutants, including PCBs (Tomasini and León‐Santiesteban 2019; Vishwakarma 2019). The ligninolytic system consists of three major peroxidases: lignin peroxidase (LiP, ‐EC 1·11·1.14‐), manganese peroxidase (MnP, ‐EC 1·11·1.13‐), versatile peroxidases (VP, ‐EC 1·11·1.16‐); and laccase (Lac, ‐EC 1·10·3.2‐), this last one belonging to phenol oxidases (Gao et al .…”

Aims To evaluate the mycoremediation of polychlorinated biphenyls (PCBs) by either single cultures or binary consortia of Pleurotus pulmonarius LBM 105 and Trametes sanguinea LBM 023. Methods and Results PCBs tolerance, removal capacity, toxicity reduction and ligninolytic enzyme expression were assessed when growing single culture and binary consortium of fungus in 217 mg l−1 of a technical mixture of Aroclor 1242, 1254 and 1260 in transformer oil. A decrease in tolerance and variation in ligninolytic enzyme secretion were observed in PCB‐amended solid media. Pleurotus pulmonarius LBM 105 mono‐culture was able to remove up to 95·4% of PCBs, whereas binary consortium and T. sanguinea LBM 023 could biodegrade about 55% after 24 days. Significant detoxification levels were detected in all treatments by biosorption mechanism. Conclusions Pleurotus pulmonarius LBM 105 in single culture had the best performance regarding PCBs biodegradation and toxicity reduction. Ligninolytic enzyme secretion changed in co‐culture. Significance and Impact of the Study The evaluation of PCBs bioremediation effectiveness of basidiomycetes consortium in terms of PCB removal, toxicity and ligninolytic enzyme production to unravel the differences between using individual cultures or consortium has not been reported. The results from this study enable the selection of P. pulmonarius LBM 105 mono‐culture to bioremediate PCBs as it showed higher efficiency compared to binary consortium with T. sanguinea LBM 023 for potential decontamination of PCB‐contaminated transformer oil.
