“…However, the microbe-mediated gold dissolution in presence of Chromobacterium violaceum with low metal mobilization did not show the formation of Au(CN) − 2 [56]. Further studies done by Brandl and Faramarzi [57] showed a better performance of Chromobacterium violaceum for mobilizing 68.5% gold in 7 days from waste PCBs. In contrast, Pseudomonas fluorescens and Pseudomonas plecoglossicida formed lower amount of dicyanoaurate.…”

“…In contrast, Pseudomonas fluorescens and Pseudomonas plecoglossicida formed lower amount of dicyanoaurate. The gold complex was more specifically unstable with Pseudomonas fluorescens due to the sorption of dicyanoaurate onto dead biomass or metal-cyanide's degradation [57]. A substantial amount of copper dissolution from ewaste was also obtained due to its high content in the waste and a faster kinetics of cyanidation.…”

Abstract:Metals with an average crustal abundance of <0.01 ppm, which are high in supply shortage due to soaring demand, can, under the excessive environmental risk and <1% recycling rate of their production, be termed as 'critical' in a limited geo-boundary. A global trend to the green energy and low carbon technologies with geopolitical scenario is challenging for the sustainable reclamation of these metals from secondary resources. Among the available processes, bio-reclamation can be a sustainable technique for extracting and concentrating these metals. Therefore, in the present paper, the potential reclamation of critical metals (including rare earth elements, precious metals, and a common nuclear fuel element, uranium) via their interaction with microbe/s has been reviewed.

Abstract:We investigated a microbe-based approach to be used for the biorecovery of valuable metals from e-waste. E-waste is a heterogeneous matrix at the microbial scale. Therefore, this study aims at taking advantage of bacterial-fungal (BF) interactions in order to mobilize and immobilize a selected metal present in e-waste. We used cadmium (Cd) and a selection of Cd-tolerant microorganisms from our culture collection or isolated from a naturally cadmium-contaminated soil. Several experiments were designed in order to use the synergistic bioremediation capabilities of BF couples to mobilize and immobilize Cd from a culture medium. Initial results showed that the selected synergistic BF couples are more tolerant to Cd concentrations than the organisms alone. However, setting the conditions leading to effective immobilization of this toxic metal still need further work. Using microbial consortia rather than single species represents an innovative alternative to traditional bioremediation approaches for the development of new biotechnological approaches in urban mining.
