“…In addition to algae, fungi have also been applied for the biosorption of heavy metals; Ahmed El-Gendy et al 2017 applied Fungi for the removal of heavy metal ions (e.g.,) cadmium (Cd 2+ ), copper (Cu 2+ ), and lead (Pb 2+ ) [47]. Bano A et al 2018, applied fungi for the removal of iron and zinc elements from water [48]. Gupta et al 2016 wrote a comprehensive review of the application of fungi, algae and other microbes in heavy metal biosorption [49].…”

The presence of inorganic pollutants such as metal ions (Ni2+, Pb2+, Cr6+) in water, probably by long-term geochemical changes and from the effluents of various industries, causes diseases and disorders (e.g., cancer, neurodegenerative diseases, muscular dystrophy, hepatitis, and multiple sclerosis). Conventional methods for their removal are limited by technical and economic barriers. In biosorption, low-cost and efficient biomaterials are used for this purpose. In this study, Brassica Campestris stems from the agriculture waste and has been used for the removal of Ni2+, Cr6+ and Pb2+ ions from an aqueous solution containing all the ions. Effect of different parameters, e.g., pH, contact time, metal ion initial concentration, adsorbent dose, agitation rate and temperature were analyzed and optimized. The adsorbent worked well for removal of the Pb2+ and Cr6+ as compared to Ni2+. The atomic absorption spectrophotometer (AAS) and FTIR investigation of adsorbent before and after shows a clear difference in the adsorbent capability. The highest adsorption percentage was found at 98%, 91%, and 49% respectively, under the optimized parameters. Furthermore, the Langmuir isotherm was found better in fitting to the experimental data than that of the Freundlich isotherm.

“…The Aspergillus flavus and Sterigmatomyceshalophilus showed the best average adsorption of heavy metal ions with an average of 86 and 83%. Obligate halophilic fungi remove iron and zinc ions effectively from an aqueous medium with an average of 85 and 84% [52].…”

Manuscript discussed the role of different parameters for the metal ions removal from industrial waste water. The metal ions removal from waste water is essential to decrease the diseases and environmental hazards caused by heavy metal ions. The different parameters of adsorption including the effect of contact time, dose, pH, temperature, kinetics and Brunauer-Emmett-Teller analysis is discussed. This manuscript focuses on biosorption of metal ions, competitive adsorption of metal ions and ligand based adsorption of metal ions. This manuscript also focuses on the commercially available adsorbent used in the removal of metal ions efficiently including polymeric adsorbent and activated carbon.

“…can biosorb toxic metals, such as U, Th, Sr, Ni, Zn, Pb, Cr, and As. [17][18][19] Uranium ion can cause several risks to human health, the main ones are effects on the kidneys (inflammation) and change in urine color, consumption of water and food contaminated with high concentrations of uranium increases the risk of lung and bone cancer. 20 Studies on uranium uptake of fungal biomass have focused on biosorption mechanisms, but current studies have shown that fungi can use other pathways to reduce the contamination of radionuclides in the environment.…”

Penicillium piscarium can be indicated as promising in the treatment of sites contaminated with uranium. Thus, this research aimed to analyze the P. piscarium dead biomass in uranium biosorption. This fungus was previously isolated from a highly contaminated uranium mine located in Brazil. Biosorption tests were carried out at pH 3.5 and 5.5 in solutions contaminated with concentrations of 1 to 100 mg/L of uranium nitrate. Our results showed that the dead biomass of P. piscarium was able to remove between 93.2 and 97.5% uranium from solutions at pH 3.5, at the end of the experiment, the pH of the solution increased to values above 5.6. Regarding the experiments carried out in solutions with pH 5.5, the dead biomass of the fungus was also able to remove between 38 and 92% uranium from the solution, at the end of the experiment, the pH of the solution increased to levels above 6.5. The analysis of electron microscopy, Energy-dispersive spectroscopy, and X-ray fluorescence demonstrated the high concentration of uranium precipitated on the surface of the fungal biomass. These results were impressive and demonstrate that the dead biomass of P. piscarium can be an important alternative to conventional processes for treating water contaminated with heavy metals, and we hope that these ecofriendly, inexpensive, and effective technologies be encouraged for the safe discharge of water from industrial activities.
