“…It was analyzed that A. niger can remove more than 90% As at all tested concentrations [ 17 ]. This involves the combination of several processes such as entrapment, chelation, micro-precipitation, and complexation as a remedial activity from contaminated sites [ 8 ]. The extreme biosorption value was documented around 108.08 mg g −1 at As concentration of 600 mg L −1 [ 150 ].…”

“…These beneficial microbes are very useful for the bioremediation of toxic metals. Metal-tolerant microorganisms can persist in polluted areas and be utilized for bioremediation purposes [ 7 , 8 ]. Microorganisms have evolved various biochemical mechanisms to feed the As oxyanions, either as an electron donor or an electron acceptor (AsV) for anaerobic respiration and to support the chemo-autotrophic fixation of carbon dioxide (CO 2 ) into the cell carbon [ 9 ].…”

Arsenic contamination in water and soil is becoming a severe problem. It is toxic to the environment and human health. It is usually found in small quantities in rock, soil, air, and water which increase due to natural and anthropogenic activities. Arsenic exposure leads to several diseases such as vascular disease, including stroke, ischemic heart disease, and peripheral vascular disease, and also increases the risk of liver, lungs, kidneys, and bladder tumors. Arsenic leads to oxidative stress that causes an imbalance in the redox system. Mycoremediation approaches can potentially reduce the As level near the contaminated sites and are procuring popularity as being eco-friendly and cost-effective. Many fungi have specific metal-binding metallothionein proteins, which are used for immobilizing the As concentration from the soil, thereby removing the accumulated As in crops. Some fungi also have other mechanisms to reduce the As contamination, such as biosynthesis of glutathione, cell surface precipitation, bioaugmentation, biostimulation, biosorption, bioaccumulation, biovolatilization, methylation, and chelation of As. Arsenic-resistant fungi and recombinant yeast have a significant potential for better elimination of As from contaminated areas. This review discusses the relationship between As exposure, oxidative stress, and signaling pathways. We also explain how to overcome the detrimental effects of As contamination through mycoremediation, unraveling the mechanism of As-induced toxicity.

“…Bioaugmentation is based on the inoculation of degrading microbial strains which have been selected under laboratory conditions because of their capacity to rapidly degrade the target contaminants. The degrading strains can be inoculated singly or in combination as microbial consortia (Poi et al, 2017;Hassan et al, 2020). In some cases, fungi (mycoremediation) and bacteria are simultaneously inoculated (Zaborowska et al, 2019) with potential synergistic effects.…”

The field of soil biological remediation was initially focused on the use of microorganisms. For organic contaminants, biostimulation and bioaugmentation were the strategies of choice. For heavy metals, bioremediation was centered on the feasibility of using microorganisms to reduce metal toxicity. Partly due to the impossibility to degrade metals, phytoremediation emerged proposing the use of plants to extract them (phytoextraction) or reduce their bioavailability (phytostabilization). Later, microbial-assisted phytoremediation addressed the inoculation of plant growth-promoting microorganisms to improve phytoremediation efficiency. Similarly, plant-assisted bioremediation examined the stimulatory effect of plant growth on the microbial degradation of soil contaminants. The combination of plants and microorganisms is nowadays often recommended for mixed contaminated soils. Finally, phytomanagement emerged as a phytotechnology focused on the use of plants and associated microorganisms to decrease contaminant linkages, maximize ecosystem services, and provide economic revenues. Although biological remediation methods have been in use for decades, the truth is that they have not yet yielded the expected results. Here, we claim that much more research is needed to make the most of the many ways that microorganisms have evolutionary developed to access the contaminants and to better understand the soil microbial networks responsible, to a great extent, for soil functioning.

“…Transcriptome has been widely used to analyze the functional genes and molecular mechanisms related to the growth and development of edible fungi, including Agrocybe aegerita, Cordyceps militaris and Ganoderma lucidum ( Hassan et al, 2020 , Xu et al, 2021 ). In recent years, the transcriptomic research on fruit and vegetable lignification has been gradually deepened.…”
