“…Degradation did not result in a formation of oestrogenic metabolites at concentrations high enough to overcome the activity of the parental compounds. Same assays were performed in the treated sludge, in addition to D. magna, Vibrio fisherii and germination tests also reported in [80]. Those results showed a slightly increase in the dioxin-like activity of the treated sludge, highlighting the need of performing a broad spectrum of biological assays in order to assess the overall potential risk.…”

“…Degradation percentages of several UV filters and some of their metabolites in a solid-phase treatment of sewage sludge by T. versicolor are shown in [80]. As treatments were performed in sterile conditions, the near 100% removal efficiencies of those compounds can be attributed to fungal biotransformation.…”

Organic UV filters used in cosmetics and sunlight protection of materials are considered emerging contaminants. These xenobiotic compounds occur in the environment in relevant concentrations and display critical properties such as environmental persistence and bioaccumulation. They enter the environment mainly through the liquid effluent of wastewater treatment plants (WWTPs), but, due to their high hydrophobicity, they are also adsorbed in WWTP sludge, that is, eventually spread on agricultural fields as fertilizer. The treatment of WWTP sludge with the white-rot fungi Trametes versicolor has emerged as a feasible alternative to current conventional treatment processes to degrade them in a range from 87% in the case of 3-(4 0 -methylbenzylidene) camphor (4-MBC) to 100% of benzophenone-3 (BP3) and its metabolite 4,4 0 -dihydroxybenzophenone (4DHB). When treating the sewage sludge to remove sunscreens content, it is crucial to establish the biological activity profile along the process. metabolites possessed significant oestrogenic activity at the produced concentrations. These results demonstrate the suitability of fungi to degrade sunscreen agents and eliminate their oestrogenic activity.

“…Studies have further shown that the group most widely associated with bioremediation are the white rot fungi (majorly basidiomycetes). The white rot fungi can break down PhACs with the help of their relatively advanced enzymatic systems which includes the lignin modifying enzymes (LMEs; Rodríguez-Rodríguez et al, 2013 ). Basically, the utilization of fungi in bioremediation, which is referred to as mycoremediation, is possible due to the unique ability of fungi to metabolize various inorganic and organic xenobiotics (use them as carbon and energy source), with the subsequent release of harmless metabolites or their complete assimilation.…”

“…In the third mechanism, an array of extracellular fungal enzymes is expressed, this could include phenol-oxidases (laccases) and peroxidases (versatile, lignin, manganese peroxidases), among others ( Rodríguez-Rodríguez et al, 2013 ). Interestingly, a recent study demonstrated the ability a dye decolorizing peroxidase 4 (DyP4), to efficiently breakdown PhACs like furosemide and paracetamol, with enhanced degradation of sulfamethoxazole, salicylic acid and methyl paraben in the presence of redox mediators ( Athamneh et al, 2022 ).…”

The potential of fungi in the bioremediation of pharmaceutically active compounds: a comprehensive review

The ability of fungal species to produce a wide range of enzymes and metabolites, which act synergistically, makes them valuable tools in bioremediation, especially in the removal of pharmaceutically active compounds (PhACs) from contaminated environments. PhACs are compounds that have been specifically designed to treat or alter animal physiological conditions and they include antibiotics, analgesics, hormones, and steroids. Their detrimental effects on all life forms have become a source of public outcry due their persistent nature and their uncontrolled discharge into various wastewater effluents, hospital effluents, and surface waters. Studies have however shown that fungi have the necessary metabolic machinery to degrade PhACs in complex environments, such as soil and water, in addition they can be utilized in bioreactor systems to remove PhACs. In this regard, this review highlights fungal species with immense potential in the biodegradation of PhACs, their enzymatic arsenal as well as the probable mechanism of biodegradation. The challenges encumbering the real-time application of this promising bioremediative approach are also highlighted, as well as the areas of improvement and future perspective. In all, this paper points researchers to the fact that fungal bioremediation is a promising strategy for addressing the growing issue of pharmaceutical contamination in the environment and can help to mitigate the negative impacts on ecosystems and human health.
