Biosorption and Bioleaching of Heavy Metals from Electronic Waste Varied with Microbial Genera

Industrialization and technological advancements have led to the exploitation of natural resources and the production of hazardous wastes, including electronic waste (E-waste). The traditional physical and chemical techniques used to combat E-waste accumulation have inherent drawbacks, such as the production of harmful gases and toxic by-products. These limitations may be prudently addressed by employing green biological methods, such as biosorption and bioleaching. Therefore, this study was aimed at evaluating the biosorption and bioleaching potential of seven microbial genera associated with electronic waste treatment. The results demonstrated significant biosorption and bioleaching capabilities, suggesting that these biological processes can effectively reduce the toxicity and volume of electronic waste, thereby presenting sustainable alternatives to conventional methods. This research contributes to the understanding of bioremediation techniques in the management of E-waste, highlighting the importance of utilizing microbial processes for environmental sustainability.
