“…Clay minerals, e.g., montmorillonite, possess high cation exchange capacities (CECs), and can efficiently reduce metal bioavailability and toxicity (Sandrin and Maier 2003 ). Moreover, metals in soil may react with the organic pollutants to affect the speciation, bioavailability, and toxicity of the metal and the organic pollutant (Ceci et al 2019 ).…”

Much research has been carried out on the bacterial bioremediation of soil contaminated with petroleum hydrocarbons and toxic metals but much less is known about the potential of fungi in sites that are co-contaminated with both classes of pollutants. This article documents the roles of fungi in soil polluted with both petroleum hydrocarbons and toxic metals as well as the mechanisms involved in the biotransformation of such substances. Soil characteristics (e.g., structural components, pH, and temperature) and intracellular or excreted extracellular enzymes and metabolites are crucial factors which affect the efficiency of combined pollutant transformations. At present, bioremediation of soil co-contaminated with petroleum hydrocarbons and toxic metals is mostly focused on the removal, detoxification, or degradation efficiency of single or composite pollutants of each type. Little research has been carried out on the metabolism of fungi in response to complex pollutant stress. To overcome current bottlenecks in understanding fungal bioremediation, the potential of new approaches, e.g., gradient diffusion film technology (DGT) and metabolomics, is also discussed. Key points • Fungi play important roles in soil co-contaminated with TPH and toxic metals. • Soil characteristics, enzymes, and metabolites are major factors in bioremediation. • DGT and metabolomics can be applied to overcome current bottlenecks.

We present a case study report into nutritional competition between Trichoderma spp. isolated from wild raspberries and fungal phytopathogenic isolates (Colletotrichum sp., Botrytis sp., Verticillium sp. and Phytophthora sp.), which infect soft fruit ecological plantations. The competition was evaluated on the basis of nutritional potentiates. Namely, these were consumption and growth, calculated on the basis of substrate utilization located on Biolog® Filamentous Fungi (FF) plates. The niche size, total niche overlap and Trichoderma spp. competitiveness indices along with the occurrence of a stressful metabolic situation towards substrates highlighted the unfolding step-by-step approach. Therefore, the Trichoderma spp. and pathogen niche characteristics were provided. As a result, the substrates in the presence of which Trichoderma spp. nutritionally outcompete pathogens were denoted. These were adonitol, D-arabitol, i-erythritol, glycerol, D-mannitol and D-sorbitol. These substrates may serve as additives in biopreparations of Trichoderma spp. dedicated to plantations contaminated by phytopathogens of the genera Colletotrichum sp., Botrytis sp., Verticillium sp. and Phytophthora sp.

“…A comparatively much lower focus has been given to zygomycetes and ascomycetes, as well as on the role of intracellular enzymes in fungal bioremediation. The scientific literature is rich in review works dedicated to lignin-modifying enzymes, that is, oxidoreductases [6•, 12, 16••, 87•, 88], and to the overall review of the use of filamentous fungi or their enzymes for the bioremediation of polycyclic aromatic hydrocarbons [17, 87•, 89], pharmaceutically active compounds [90••], pesticides [33, 90••], insecticides [91,92], dyes [33,86], hormones [93], and heavy metals [21,30,85], together with a description of the conversion pathways. Furthermore, substantial knowledge has been acquired on fungal morphology and coupling whiterot fungi or their enzymes with various reactor designs [16••, 73••] as well as on the synergistic effect of using coculture strategies [22•], or combining white-rot fungi with nanomaterials [55•].…”

Propose of Review Anthropogenic activities are saturating wastewater treatment plants and the environment with an increasing range of organic and inorganic compounds, impairing ecosystems and health. Filamentous fungi, with characteristic filamentous growth, array of extracellular and intracellular enzymes, production of surfactants, cell wall biosorption properties, and symbiotic momentum, can contribute to a paradigm shift on the perception of anthropogenic pollution. This review provides a critical analysis of the main bottlenecks for feasible filamentous fungus-including processes and proposes a holistic approach for pollution mitigation using filamentous fungi. Recent Findings Filamentous fungi can convert ordinary sidestreams into, e.g., feed proteins and biofuels. Economic and environmental studies support integration in established processes. Intersectoral initiatives, and economic and environmental studies, need to be motivated to increase the range of processes. Although massively studied, the transfer of fungal processes for the removal of micropollutants into real matrices is difficult. It needs to be supported by omics technologies for the study of microbial networks, and by efficient analytical techniques to clarify detoxification potential. The area can benefit from knowledge integration from fungal growth in ordinary sidestreams, and from economic and environmental studies. Summary The interest in filamentous fungi for pollution mitigation is corroborated by an overwhelming amount of research; however, no full-scale applications are currently known. Environmental pollution is a reality and production of ordinary sidestreams and micropollutant-rich wastewaters continuous. The establishment of filamentous fungal processes needs collaboration among governmental authorities, industries, and academics in order to tackle knowledge gaps within the area and propose a holistic approach.
