“…[5][6][7] Currently, the growing interest in this species is to a large extent directed toward potential applications in biotechnology, such as remediation of soils and aquifers that have been contaminated with heavy metals or radionuclides, and a biocatalyst in microbial fuel cells. [7][8][9][10][11][12] S. oneidensis can grow not only aerobically, but also anaerobically with a variety of organic and inorganic substances as the terminal electron acceptor. This microbe has methylmenaquinone (MMK) besides UQ and MK, and the use of MK-minus mutants revealed that MK and/or MMK were required for the reduction of Fe(III), fumarate, and nitrate.…”

Ubiquinone and menaquinone play important roles in microbial respiratory chains. S. oneidensis is a facultative anaerobe, and it has been known that this microbe requires menaquinone (MK) and/or methylmenaquinone (MMK) to reduce inorganic and organic compounds, such as Fe(III), Mn(IV), fumarate, and nitrate, under anaerobic conditions. In this article, we show that voltammetry is useful to quantify ubiquinone (UQ), MK and MMK located in the cytoplasmic membrane simply by heating the microbe (thermal lysis) deposited on an indium-tin oxide electrode. It was found that the microbe predominantly produced UQ under aerobic conditions, while the production was switched to that of MMK under anaerobic conditions. This transition occurred at a dissolved oxygen concentration of ∼0.3 mg L −1 . It was also found in this study that the total quinone concentration (UQ + MK + MMK) in a single cell was constant at all stages of the culture in a nutrition broth, suggesting that the cytoplasmic membrane was saturated with the quinones. The reduction of Fe(III) citrate with S. oneidensis was also studied. It was found that this microbe decreased the UQ and MMK levels to 45% and 39% of the initial values, respectively, after finishing the reduction.

“…Co-precipitation is another phenomenon where elements combine with metal oxide minerals during their precipitation [38] . Citrobacter and Serratia is are common example of biomineralization, which release phosphate ligand and form uranyl ions [52] .

Radioactive nuclides are utilized in large quantities in different sectors such as nuclear power plants to address energy demand. As a result, there is a massive amount of radioactive waste produced from nuclear sites and its spent sources including mining activities, nuclear weapons recycling, nuclear weapon, and nuclear energy generation. The widespread discharge of radionuclides into the environment and their mobility is a worldwide matter of concern given its health risks to living organisms. Hence, there is a need to embrace sustainable technologies for the effective management of radioactive nuclide wastes. Bioremediation is a promising and eco-friendly approach to remediate radioactive waste. The current review discussed various modes of bioremediation such as microbial, phyto, and myco-remediation for the management of radioactive waste. The interaction of microorganisms with various actinides and their fission products are also discussed. Moreover, a sustainable and efficient strategy for radioactive nuclide waste management in developing countries is also highlighted.

This paper discusses circular economy (CE) as an option to mitigate the environmental impacts of mining operations, and a framework based on the three dimensions of sustainability, the possible uses of mining wastes, the life cycle, and the systems approaches to determine the policies that will induce initiatives towards designing out wastes for a mining-based circular economy. Previous research has been reviewed to determine CE configuration and the basis for the framework to guide in the development of CE-related mining policies. The Chinese model of circular economy, noted for the introduction of industrial symbiosis through eco-industrial parks at the meso level, and public participation at the macro level, forms the basic structure of the framework aimed at curbing mining waste, and closing the loop in mining. Holistic research is important in taking proactive CE technology actions, strategic measures, and policies, which can use life cycle assessment (LCA) methods (environmental and social LCA and life cycle costing) and systems dynamic modeling. With systems dynamic modeling, the framework introduced in this work can be expanded to cover as many important aspects as possible, and can check for areas of policy resistance that have been the reason for most policy failures.
