“…Liu et al [ 97 ] also reported that the biomineralisation of Cu 2+ with the participation of fungi is associated with gluconeogenesis because of the strong affinity of triose-phosphate isomerase to mycogenic copper nanoparticles. The tolerance of the fungi Aspergillus awamori , Aspergillus flavus , and Aspergillus niger to Ni 2+ was also confirmed by Rose and Devi [ 99 ]. It is not without reason that a molecular sieve in our study was found to be effective in the remediation of soil polluted with Ni 2+ and Cu 2+ , while zeolite was found to be effective in soil with Zn 2+ .…”

Despite numerous studies on the influence of heavy metals on soil health, the search for effective, eco-friendly, and economically viable remediation substances is far from over. This encouraged us to carry out a study under strictly controlled conditions to test the effects of Cu2+, Ni2+, and Zn2+ added to soil in amounts of 150 mg·kg−1 d.m. of soil on the soil microbiome, on the activity of two oxidoreductases and five hydrolases, and on the growth and development of the sunflower Helianthus annunus L. The remediation substances were a molecular sieve, halloysite, sepiolite, expanded clay, zeolite, and biochar. It has been demonstrated that the most severe turbulences in the soil microbiome, its activity, and the growth of Helianthus annunus L. were caused by Ni2+, followed by Cu2+, and the mildest negative effect was produced by Zn2+. The adverse impact of heavy metals on the soil microbiome and its activity was alleviated by the applied sorbents. Their application also contributed to the increased biomass of plants, which is significant for the successful phytoextraction of these metals from soil. Irrespective of which property was analysed, sepiolite can be recommended for the remediation of soil polluted with Ni2+ and zeolite—for soil polluted with Cu2+ and Zn2+. Both sorbents mitigated to the highest degree disturbances caused by the tested metals in the soil environment.

“…The fungal strain identified in the study was closely related to the Aspergillus alliaceus MH279440.1 strain in the Eurotiomycetes class (ITS identity, 100%). Previous studies also reported that Aspergillus species are isolated in heavy metal contaminated areas [11,16,29]. The presence of this type of fungi in polluted environments is based on their ability to survive in extreme conditions and metabolize various substrates as food source [14,30,31].…”

“…Metal tolerance or resistance can be defined as the ability of an organism to endure metal toxicity through one or more mechanisms to the metal/metals involved [11]. Therefore, fungi that can tolerate high metal levels (e.g., Aspergillus, Penicillium, Pleurotus, and Trichoderma) have been used as biological tools in bioremediation studies [7,8,[12][13][14][15][16].…”

Heavy metals are naturally present in the environment. As a result of human activities and some natural events, mixing of these metals in water, air and soil is one of the most serious global problems. The toxicity of these metals is also a serious global problem due to their accumulation in living things and non-biodegradable characteristics. Increasing heavy metal pollution in aquatic and terrestrial environments requires improvement strategies such as bioremediation to remove these metals from the environment for human and environmental health. In this study, fungal isolation was performed to examine fungi with heavy metal remediation potential using sand samples from Sugözü Beaches where are subjected to intense environmental effects due to human activities including industrial facilities and marine traffic. This beach is also an important nesting area for the green turtle. Aspergillus alliaceus isolated from this beach was identified using primers of internal transcribed spacer 1 and 4. To determine the tolerance of A. alliaceus to iron, zinc, cobalt and copper, the fungus was inoculated into media containing metal at different concentrations (200, 400, 600, 800, and 1000 ppm). Daily mycelium growths were recorded during a ten day incubation at 30°C. A.alliaceus was found to tolerate Fe and Zn at all concentrations. Besides, it tolerated Co and Cu up to 400 and 600 ppm, respectively. In this study, the tolerance of A. alliaceus to Fe, Zn, and Co was determined for the first time and it is recommended that it can be used efficiently in bioremediation studies.

“…Tolerance index (TI)= Growth of treated colony/ Growth of untreated colony. High Tolerance index (TI) values reflect good adaptive/ tolerance behavior against a particular heavy metal and TI value which equals or greater than one indicates absolute resistance for this metal at the tested concentration (Chen et al, 2017;Rose & Devi, 2018).…”
