“…The inhibitory concentrations ranged from 4 to 8 mg/L for Penicillium simplicissimum isolates. These results confer with the study by Mohammadian et al (2017), which also confirmed that P. simplicissimum has a higher capacity for Cu (II) uptake compared to other filamentous fungi [Fusarium verticillioides, Acremonium persicinum, Seimatosporium pistaciae Crous and Mirab. (2014), Alternaria chlamydosporigena Woudenb.…”

“…This is despite their undeniable advantages over their counterparts, the acidophilic bacteria, such as their ability to grow over a wide range of pH from 1.0 to 9, and their higher sensitivity and capacity to accumulate more heavy metals (0.40-700 mg/g) compared to bacteria biosorption (0.70-500 mg/g) (Ahemad and Kibret, 2013). Numerous researches have published findings on the biosorption of heavy metals by filamentous fungi but mostly under controlled laboratory-scale environments (Zafar et al, 2007;Ezzouhri et al, 2009;Siddiquee et al, 2013;Mohammadian et al, 2017). To understand, clearly and in detail, the progress in biosorption of heavy metals by filamentous fungi, our review has focused mainly on the biosorption of copper and cobalt from heavy metal contaminated environments ( Table 2).…”

“…It is suggested that how the combination of fungi and other microorganisms (bacteria, algae, yeast) harvest their full potential for heavy metal biosorption remains a novel research area. The resistance mechanisms developed by these microorganisms mainly for their survival shows that they are highly efficient for detoxifying metal ions in aqueous solutions (Xie et al, 2010;Mohammadian et al, 2017). Developing new technologies for bioremediation is especially relevant in areas FIGURE 1 | Typical laboratory schematic process of heavy metal biosorption by filamentous fungi (Biosorption analysis is accomplished from experiment 1 to 7).…”

Recent Advances in Biosorption of Copper and Cobalt by Filamentous Fungi

Copper (Cu) and Cobalt (Co) are among the most toxic heavy metals from mining and other industrial activities. Both are known to pose serious environmental concerns, particularly to water resources, if not properly treated. In recent years several filamentous fungal strains have been isolated, identified and assessed for their heavy metal biosorption capacity for potential application in bioremediation of Cu and Co wastes. Despite the growing interest in heavy metal removal by filamentous fungi, their exploitation faces numerous challenges such as finding suitable candidates for biosorption. Based on current findings, various strains of filamentous fungi have high metal uptake capacity, particularly for Cu and Co. Several works indicate that Trichoderma, Penicillium, and Aspergillus species have higher Cu and Co biosorption capacity compared to other fungal species such as Geotrichum, Monilia, and Fusarium. It is believed that far more fungal species with even higher biosorption capability are yet to be isolated. Furthermore, the application of filamentous fungi for bioremediation is considered environmentally friendly, highly effective, reliable, and affordable, due to their low technology pre-requisites. In this review, we highlight the capacity of various identified filamentous fungal isolates for biosorption of copper and cobalt from various environments, as well as their future prospects.

Fungi are promising materials for soil metal bioextraction and thus biomining. Here, a macrofungi-based system was designed for rapid cadmium (Cd) removal from alkaline soil. The system realized directed and rapid fruiting body development for subsequent biomass harvest. The Cd removal efficiency of the system was tested through a pot culture experiment. It was found that aging of the added Cd occurred rapidly in the alkaline soil upon application. During mushroom growth, the soil solution remained considerably alkaline, though a significant reduction in soil pH was observed in both Cd treatments. Cd and dissolved organic carbon (DOC) in soil solution generally increased over time and a significant correlation between them was detected in both Cd treatments, suggesting that the mushroom‒substratum system has an outstanding ability to mobilize Cd in an alkaline environment. Meanwhile, the growth of the mushrooms was not affected relative to the control. The estimated Cd removal efficiency of the system was up to 12.3% yearly thanks to the rapid growth of the mushroom and Cd enrichment in the removable substratum. Transcriptomic analysis showed that gene expression of the fruiting body presented considerable differences between the Cd treatments and control. Annotation of the differentially expressed genes (DEGs) indicated that cell wall sorption, intracellular binding, and vacuole storage may account for the cellular Cd accumulation. In conclusion, the macrofungi-based technology designed in this study has the potential to become a standalone biotechnology with practical value in soil heavy metal removal, and continuous optimization may make the system useful for biomining.

“…Microorganisms are a contact group of organisms, which are an important element for successful land reclamation because of their major role in nutrient cycling, plant establishment, biogeochemical transformations of present elements, and soils formation [1], [2], [3]. These are organisms that are highly adaptable to life under the conditions of heavily-burdened areas and extreme stress from the presence of toxic elements [4], [5], [6]. These organisms have an enormous biotechnological potential in the speciation of elements in post-mining substrates, thereby influencing the course of further revitalization of contaminated sites through the biotransformation processes of present toxic metals and semimetals [7], [8], [9], [10], [11].…”

Poproč post-mining area in Slovakia is an old environmental burden which has been contaminated by toxic metals and semi-metals, predominantly arsenic and antimony, in connection with the extraction of antimony ores. Nowadays, revitalization work is undergoing in the closed mine with three adjacent sludge lagoons. The outcomes deal with anthropogenic manifestations of mining in-situ and their influences on microbes. Using the BIOLOG test system we identified representatives of indigenous microbes, whose adaptation to high levels of toxic metals and semi-metals are one of the main bioindicators of the state of the post-mining environment and a basic indicator of the evolution of effects on organisms of a higher ecological level. The analyses of microbial diversity in Poproč found the strain of Firmicutes to be the most abundant, with the highest diversity in the genus Bacillus. Based on the biochemical tests, the Bacillus genus was confirmed to be highly adaptable to the change in biogeochemical conditions in metalcontaminated substrates. The variable parameters of the identified representatives of the Bacillus genus correspond to its high diversity, which has been confirmed by a set of oxidative and assimilation tests.
