“…Bioremediation is an ecologically sound technology that restricts the strain on natural resources as linked to conventional methods [7]. It embraces the action of living organisms such as plants, algae, bacteria, and fungi [8]. These organisms tend to absorb toxic pollutants and show great tolerance potential under stress environments owing to their innate adsorption capability [9].…”

Widespread lead (Pb) contamination prompts various environmental problems and accounts for about 1% of the global disease burden. Thus, it has necessitated the demand for eco-friendly clean-up approaches. Fungi provide a novel and highly promising approach for the remediation of Pb-containing wastewater. The current study examined the mycoremediation capability of a white rot fungus, P. opuntiae, that showed effective tolerance to increasing concentrations of Pb up to 200 mg L−1, evidenced by the Tolerance Index (TI) of 0.76. In an aqueous medium, the highest removal rate (99.08%) was recorded at 200 mg L−1 whereas intracellular bioaccumulation also contributed to the uptake of Pb in significant amounts with a maximum of 24.59 mg g−1. SEM was performed to characterize the mycelium, suggesting changes in the surface morphology after exposure to high Pb concentrations. LIBS indicated a gradual change in the intensity of some elements after exposure to Pb stress. FTIR spectra displayed many functional groups including amides, sulfhydryl, carboxyl, and hydroxyl groups on the cell walls that led to binding sites for Pb and indicated the involvement of these groups in biosorption. XRD analysis unveiled a mechanism of biotransformation by forming a mineral complex as PbS from Pb ion. Further, Pb fostered the level of proline and MDA at a maximum relative to the control, and their concentration reached 1.07 µmol g−1 and 8.77 nmol g−1, respectively. High Pb concentration results in oxidative damage by increasing the production of ROS. Therefore, the antioxidant enzyme system provides a central role in the elimination of active oxygen. The enzymes, namely SOD, POD, CAT, and GSH, served as most responsive to clear away ROS and lower the stress. The results of this study suggested that the presence of Pb caused no visible adverse symptoms in P. opuntiae. Moreover, biosorption and bioaccumulation are two essential approaches involved in Pb removal by P. opuntiae and are established as worthwhile agents for the remediation of Pb from the environment.

“…Examples of these activities include the agricultural use of chemical fertilizers and pesticides, different types of medications such as antibiotics, a great variety of food additives, and soaps, shampoos, and oils, among other products, in the personal care sector. Heavy metals, compounds such as PAHs, dyes, phenols, and many other recalcitrant compounds form part of the waste and/or effluent generated by the mining, petrochemical, food, and textile industries and often contaminate the soil and water bodies when they are not subject to adequate treatment prior to discharge (Yadav et al, 2021;Noman et al, 2019;Garzón-Zúñiga et al, 2018;Rawat et al, 2016). To date, numerous reports have been published on the effectiveness of fungi in removing different compounds via mycelial biosorption or biomineralization and biotransformation (Shourie and Vijayalakshmi, 2022;Bokade et al, 2021;Ijoma et al, 2017).…”

The environment pollution or contamination is a serious problem, a great deal of research is being undertaken to combat contaminants such as xenobiotic and recalcitrant compounds, particularly heavy metals, dyes,phenolic compounds and other recalcitrant pollutants produced by a wide range of industrial activities. These compounds have an adverse impact on the environment, particularly when generated by industrial processes and then disposed off without adequate treatment. Mycoremediation is defined as the use of fungi for bioremediation, especially degradation or retention of contaminants. Biosorption and bioaccumulation are two of the mechanisms by which fungi remove contaminants through mycelium. In many cases, these processes involve metabolization and even mineralization of these contaminants, corresponding to a biological contaminant removal system with great potential for use in bioremediation processes. The present review describes the unique characteristics of fungal mycelium that make it a biomaterial with potential applications in various fields of biotechnology, specifically evaluating its biosorption/bioaccumulation properties and potential application for the bioremediation of different water-borne contaminants. This review focus on the researches conducted on the bioremediation of inorganic and organic pollutants, the mechanisms involved in the process, and the main environmental factors affecting it. Moreover, kinetics and equilibrium modeling of the removal efficiency achieved via biosorption/bioaccumulation is analyzed in order to better understand these processes and overcome some of the technical barriers to their large-scale application in the mycoremediation of wastewater. Key words: Bioaccumulation, Biosorption, Fungi, Mycoremediation, Xenobiotics

“…The previous advantages of mushrooms are mainly to the result of their immense hyphal networks, which strengthen growth through the production of multi-purpose extracellular enzymes, increasing the surface area-to-volume ratio, increasing the capabilities towards complex contaminants, enhancing the adaptability to fluctuating temperatures and pH, and possessing a metal-binding protein [71]. It is worth mentioning that the myco-remediation of different environmental pollutants can be applied for the removal or biodegradation of polluted soil and water via certain mechanisms, including biodegradation, biosorption, biotransformation, bioaccumulation, bioconversion, precipitation, and surface sequestration [69,72,73]. More details concerning these mechanisms and a comparison between them is presented in Table 3.…”

“…Different factors controlling myco-remediation by Pleurotus ostreatus are presented in this table, including the substrate, growth conditions, and the kinds of pollutants, and their concentrations. The biodegradation of pollutants by Pleurotus ostreatus mainly depends on many factors, including the growth conditions and the kinds of pollutants, and the mechanism of this process is linked to certain enzymes, such as manganese peroxidase, lignin peroxidase, and laccase [21] Many studies discussed the role of Pleurotus ostreatus in the myco-remediation process via the consideration of different perspectives, such as the myco-remediation of chlorinated pesticides [81], the accumulation of metals in fruiting bodies [83], and the biodegradation of decabromodiphenyl ethane [21], as well as including some reviews that include those published by Akhtar and Mannan [84], Pini and Geddes [85], Kumar and Dwivedi [86], and Yadav et al [72].…”

The field of biotechnology presents us with a great chance to use many organisms, such as mushrooms, to find suitable solutions for issues that include the accumulation of agro-wastes in the environment. The green biotechnology of mushrooms (Pleurotus ostreatus L.) includes the myco-remediation of polluted soil and water as well as bio-fermentation. The circular economy approach could be effectively achieved by using oyster mushrooms (Pleurotus ostreatus L.), of which the substrate of their cultivation is considered as a vital source for producing biofertilizers, animal feeds, bioenergy, and bio-remediators. Spent mushroom substrate is also considered a crucial source for many applications, including the production of enzymes (e.g., manganese peroxidase, laccase, and lignin peroxidase) and bioethanol. The sustainable management of agro-industrial wastes (e.g., plant-based foods, animal-based foods, and non-food industries) could reduce, reuse and recycle using oyster mushrooms. This review aims to focus on the biotechnological applications of the oyster mushroom (P. ostreatus L.) concerning the field of the myco-remediation of pollutants and the bio-fermentation of agro-industrial wastes as a sustainable approach to environmental protection. This study can open new windows onto the green synthesis of metal-nanoparticles, such as nano-silver, nano-TiO2 and nano-ZnO. More investigations are needed concerning the new biotechnological approaches.
