“…Various harmful compounds can be degraded by fungi. Changing local soil and water conditions can aid in fostering biological activity and, as a result, the degradation/removal of toxic substances via mycoremediation (Singh and Gauba, 2014). Fungi have also been proven to be effective in the removal of heavy metals such as lead (Pb) and cadmium (Cd).…”

Bioremediation is a branch of biotechnology that employs the use of living organisms, like microalgae and fungi, in the removal of contaminants, pollutants, and toxins from soil, water, and other environments. The study was design to know and evaluate the efficiency of fungi to remediate two types of heavy metals (Pb and Cd), by using different concentrations (5, 15, 35, and 50ppm). Results revealed that the lowest applied dose (5ppm) of both tested heavy metals had the highest reduction percent by using two fungal stains Aspergillus niger and Candida albicans were remove lead by 85.6 and 84.2%, while for cadmium were 80 and 78.4% respectively. Statistically significant differences (P≤0.05) were observed between control and the treatments for both tested heavy metals. Highest heavy metals removal was found at the end of experiment (20 days).

“…Fungi may accumulate these metals from water and store them in their tissues because they are already in their simplest condition and will not be degraded further (mycelia or fruiting mushroom bodies). After being utilized in mycoremediation, mushrooms used for this purpose must be treated as hazardous waste (Singh and Gauba, 2014).…”

“…Anthropogenic and natural activities discharge poisonous heavy metals into the surroundings ( Singh et al., 2018 ), that might be non-degradable and long persisting in the environment ( Taamalli et al., 2014 ), causing sever harmful influences on the environment, and food chains ( Mahmood and Malik, 2014 ). Zinc (Zn(II)) is an important microelement for livings, however, the elevated levels of Zn (II) are harmful and threaten the lives of many organisms ( Salem and Fouda, 2020 ).…”

“…Fungal tolerance mechanisms involve mobilization, immobilization, and biotransformation. Mobilization of metals occurs by heterotrophic and auxotrophic leaching, complexation/chelation by various metabolites, whereas immobilization occurs due to metal sorption with the biomass or exopolymers, intracellular sequestration and precipitation as organic and inorganic compounds ( Singh et al., 2018 ). Some microorganisms show an excellent bio-transformational efficiency, transforming the poisonous chemical to nontoxic forms that permit the microbe to overcome the toxicity of pollutants ( Mishra and Jha, 2009 ; El-Sayed, 2011 ; El-Sayed and Shindia, 2011 ; Mohamed et al., 2019 ).…”

Evaluating the mechanism of tolerance and biotransformation Zn(II) ions by Fusarium solani based on the different physiological was the objective of this work. The physical properties of synthesized ZnONPs was determined by UV-spectroscopy, transmission electron microscope, and X-ray powder diffraction. The structural and anatomical changes of F. solani in response to Zn(II) was examined by TEM and SEM. From the HPLC profile, oxalic acid by F. solani was strongly increased by about 10.5 folds in response to 200 mg/l Zn(II) comparing to control cultures. The highest biosorption potential were reported at pH 4.0 (alkali-treated biomass) and 5.0 (native biomass), at 600 mg/l Zn(II) concentration, incubation temperature 30 °C, and contact time 40 min (alkali-treated biomass) and 6 h (native biomass). From the FT-IR spectroscopy, the main functional groups implemented on this remediation were C–S stretching, C=O C=N, C–H bending, C–N stretching and N–H bending. From the EDX spectra, fungal cellular sulfur and phosphorus compounds were the mainly compartments involved on ZN(II) binding.

Remediating soils contaminated with heavy metals due to urbanization and industrialization is very important not only for human health but also for ecosystem sustainability. Of the available remediation technologies for heavy metal-contaminated soils, phytoremediation is a relatively low-cost environmentfriendly technology which preserves biodiversity and soil fertility. The application of plant growth-promoting bacteria (PGPB) during the phytoremediation of heavy metal-contaminated soils can enhance plant growth against heavy metal toxicity and increase heavy metal removal efficiency. In this study, the sources of heavy metals that have adverse effects on microorganisms, plants, and humans, and the plant growthpromoting traits of PGPB are addressed and the research trends of PGPB-assisted phytoremediation over the last 10 years are summarized. In addition, the effects of environmental factors and PGPB inoculation methods on the performance of PGPB-assisted phytoremediation are discussed. For the innovation of PGPB-assisted phytoremediation, it is necessary to understand the behavior of PGPB and the interactions among plant, PGPB, and indigenous microorganisms in the field.
