The Deep Geological Repository (DGR) is the preferred option for final disposal of high-level radioactive waste. Microorganisms could affect safety DGR by altering mineralogical properties compacted bentonite or inducing corrosion metal canisters. In this work, impact physicochemical parameters (bentonite dry density, heat shock, electron donors/acceptors) on microbial activity, stability and copper (Cu) discs was investigated after one-year anoxic incubation at 30 ºC. No-illitization in...
Deep Geological Repositories (DGRs) consist of radioactive waste contained in corrosion-resistant canisters, surrounded by compacted bentonite clay, and buried few hundred meters a stable geological formation. The effects microbial communities on the long-term stability repository should be assessed. This study explores impact harsh conditions (60 °C, highly-compacted bentonite, low water activity), acetate:lactate:sulfate addition, evolution communities, their effect mineralogy, corrosion...
Research on eco-friendly bioremediation strategies for mitigating the environmental impact of toxic metals has gained attention in last years. Among all promising solutions, bentonite clays, to be used as artificial barriers isolate radioactive wastes within deep geological repository (DGR) concept, have emerged effective reservoir microorganisms with remarkable potential. The present study aims investigate fungi speciation and mobility selenium (Se) tellurium (Te), natural analogues 79Se...
The deep geological repository (DGR) concept consists of storing radioactive waste in metal canisters, surrounded by compacted bentonite, and placed deeply into a formation. Here, bentonite slurry microcosms with copper inoculated bacterial consortium amended acetate, lactate sulfate were set up to investigate their geochemical evolution over year under anoxic conditions. impact microbial communities on the corrosion canisters an early-stage (45 days) was also assessed. electron...
Uranium (U) is the most hazardous radionuclide in nuclear waste and its harmful effects depend on mobility bioavailability. Microorganisms can affect speciation of radionuclides their migration Deep Geological Repositories (DGR) for high level radioactive (HLW) storage. Consequently, a better understanding microbe-radionuclide interactions within DGR concept essential safe With that mind, bentonite microcosms amended with uranyl nitrate glycerol-2-phosphate were incubated six months under...
Currently, the production of radioactive waste from nuclear industries is increasing, leading to development reliable containment strategies. The deep geological repository (DGR) concept has emerged as a suitable storage solution, involving underground emplacement within stable formations. Bentonite clay, known for its exceptional properties, serves critical artificial barrier in DGR system. Recent studies have suggested stability bentonite relevant conditions, indicating potential enhance...
Uranium (U) represents the preeminent hazardous radionuclide within context of nuclear waste repositories. Indigenous microorganisms in bentonite can influence speciation and migration Deep Geological Repositories (DGRs) for storage. While bacterial communities samples have been extensively studied, impact fungi has somewhat overlooked. Here, we investigate geomicrobiological processes microcosms amended with uranyl nitrate glycerol-2-phosphate (G2P) six-month incubation. ITS sequencing...
Deep geological repositories (DGRs) stand out as one of the optimal options for managing high-level radioactive waste (HLW) such uranium (U) in near future. Here, we provide novel insights into microbial behavior DGR bentonite barrier, addressing potential worst-case scenarios leakage (e.g., U) and groundwater infiltration electron rich donors bentonite. After a three-year anaerobic incubation, Illumina sequencing results revealed bacterial diversity dominated by spore-forming microorganisms...
VIRTUAL REALITY AS AN INNOVATIVE TOOL FOR UNIVERSITY STUDENTS TO COMPREHEND THE GLOBAL CHALLENGE OF ANTIBIOTIC RESISTANCE
Abstract Approaches to DNA extraction play a crucial role in determining the variability of results obtained through 16S rRNA amplicon sequencing. Particularly, clay‐rich samples can impede efficiency various standard cultivation‐independent techniques. We conducted an inter‐laboratory comparison study thoroughly assess efficacy two published methods (kit‐based and phenol‐chloroform‐based) specifically designed for bentonite samples. To this end, we spiked Wyoming MX 80 with different mock...
