“…In addition, some Trichoderma species can transform xenobiotic agents into non-toxic compounds, e.g., pesticides such as dichlorvos, cyanide pollutants, and even heavy metals (He et al, 2014). There are reports of Trichoderma atroviride, T. harzianum sensu lato, Trichoderma koningii, and T. viride sensu lato, capable of degrading e.g., alachlor, endosulfan, methyl-parathion, monochlorobenzene, neonicotinoids, and pentachlorophenol, among others (He et al, 2014;Vacondio et al, 2015;Cheng et al, 2017;Nunes and Malmlöf, 2018;Nykiel-Szymańska et al, 2018). Therefore, fungi that act as biocontrollers may also be capable of degrading residual pesticides in the fields or within plants, representing an important tool, not only for the transition from conventional to organic agriculture, but to complement different disease management strategies and recovery of "healthy" soil microbiomes.…”

The transition from conventional to organic agriculture is often challenged by the adaptation of biological control agents to environments heavily exposed to agrochemical pollutants. We studied Trichoderma species isolated from living leaf tissues of wild Rubiacaeae (coffee family) plants to determine their fungicide tolerance and potential for bioremoval. First, we assessed the in vitro tolerance to fungicides of four Trichoderma isolates (Trichoderma rifaii T1, T. aff. crassum T2, T. aff. atroviride T3, and T. aff. strigosellum T4) by placing mycelial plugs onto solid media supplemented with seven different systemic and non-systemic fungicides. After a week, most of the fungicides did not significantly inhibit the growth of the isolates, except in the case of cyproconazole, where the only isolate able to grow was T1; however, the colony morphology was affected by the presence of fungicides. Second, biological removal potential was established for selected isolates. For this experiment, the isolates T1, T2, and T4 were independently inoculated into liquid media with the fungicides azoxystrobin, chlorothalonil, cyproconazole, and trifloxystrobin. After 14 days of incubation, a removal of up to 89% was achieved for chlorothalonil, 46.4% for cyproconazole, and 33.1% for trifloxystrobin using viable biomass. In the case of azoxystrobin, the highest removal (82.2%) occurred by adsorption to fungal biomass. Ecotoxicological tests in Daphnia magna revealed that T1 has the highest removal potential, achieving significant elimination of every fungicide, while simultaneously detoxifying the aqueous matrix (except in the case of cyproconazole). Isolate T4 also exhibited an intermediate efficiency, while isolate T2 was unable to detoxify the matrix in most cases. The removal and detoxification of cyproconazole failed with all the isolates. These findings suggest that endosphere of wild plants could be an attractive guild to find new Trichoderma species with promising bioremediation capabilities. In addition, the results demonstrate that attention should be placed when combining certain types of agrochemicals with antagonistic fungi in Integrated Pest and Disease Management strategies or when transitioning to organic agriculture.

“…Most essential heavy metals are required in plants and animals for biochemical and physiological functions. They integrate various key enzymes and have major roles in different oxidation-reduction reactions (Nunes and Malmlöf, 2018). Heavy metals such as copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), nickel (Ni), and zinc (Zn) are essential plant micronutrients that are required in very small amounts for its normal growth and development.…”

The effects of different concentrations of copper sulfate (0.2 to 5 mg L-1) on in vitro callus and shoot formation of cucumber was investigated. Four-day-old cotyledon explants from the inbred line 'Wisconsin 2843' and the commercial cultivars 'Marketer' and 'Negrito' were used. The results on callus-derived shoots showed that the optimal concentration of CuSO4 added to Murashige & Skoog (MS)-derived shoot induction medium containing 0.5 mg L-1 IAA and 2.5 mg L-1 BAP was 8-200 fold greater than in standard MS medium, and was genotype dependent. The highest genotypes response on shoot frequency and shoot number was achieved in this order by 'Marketer', 'Negrito' and 'Wisconsin 2843' with 1, 0.2 y 5 mg L-1 CuSO4 , respectively. The genotype with the lowest control performance demanded the highest concentration of CuSO4 for its optimal morphogenic response - 6- and 10-fold more in shoot frequency and shoot number, respectively. The other cultivars registered a 2-fold increase in both variables. All explants formed callus and the response on callus extension varied among cultivars. The regression analysis showed a statistically significant relationship between shoot number and concentrations of CuSO4 and absence of association with callus extension. The present results indicate that application of specific concentrations of CuSO4 higher than in standard MS medium, increases adventitious cucumber shoot organogenesis.

“…Fungal laccase-based membrane filtration, electrokinetic, adsorption, oxidation, and photocatalytic treatments are famous for PAH degradation, which steadily increases the threat to human health. Therefore, a new effective enzymatic approach in the degradation of aromatic compounds is urgently needed ( Nunes and Malmlöf, 2018 ). Mycoremediation of PAHs in the last several years with numerous fungal species has been widely reported.…”

Integrating fungi into fuel cell systems presents a promising opportunity to address environmental pollution while simultaneously generating energy. This review explores the innovative concept of constructing wetlands as fuel cells for pollutant degradation, offering a practical and eco-friendly solution to pollution challenges. Fungi possess unique capabilities in producing power, fuel, and electricity through metabolic processes, drawing significant interest for applications in remediation and degradation. Limited data exist on fungi’s ability to generate electricity during catalytic reactions involving various enzymes, especially while remediating pollutants. Certain species, such as Trametes versicolor, Ganoderma lucidum, Galactomyces reessii, Aspergillus spp., Kluyveromyce smarxianus, and Hansenula anomala, have been reported to generate electricity at 1200 mW/m3, 207 mW/m2, 1,163 mW/m3, 438 mW/m3, 850,000 mW/m3, and 2,900 mW/m3, respectively. Despite the eco-friendly potential compared to conventional methods, fungi’s role remains largely unexplored. This review delves into fungi’s exceptional potential as fuel cell catalysts, serving as anodic or cathodic agents to mitigate land, air, and water pollutants while simultaneously producing fuel and power. Applications cover a wide range of tasks, and the innovative concept of wetlands designed as fuel cells for pollutant degradation is discussed. Cost-effectiveness may vary depending on specific contexts and applications. Fungal fuel cells (FFCs) offer a versatile and innovative solution to global challenges, addressing the increasing demand for alternative bioenergy production amid population growth and expanding industrial activities. The mechanistic approach of fungal enzymes via microbial combinations and electrochemical fungal systems facilitates the oxidation of organic substrates, oxygen reduction, and ion exchange membrane orchestration of essential reactions. Fungal laccase plays a crucial role in pollutant removal and monitoring environmental contaminants. Fungal consortiums show remarkable potential in fine-tuning FFC performance, impacting both power generation and pollutant degradation. Beyond energy generation, fungal cells effectively remove pollutants. Overall, FFCs present a promising avenue to address energy needs and mitigate pollutants simultaneously.
