Evaluating nitrate removal and travel times in a bare deciduous forest soil through a column tracer experiment

Manon Frutschi, Andrea Rinaldo, Simiao Wang, Filippo Miele

In response to increased atmospheric nitrogen deposition, understanding the fate of nitrate within forest soils is crucial for predicting the ecological trajectories of soil microbial communities. This study leverages a controlled soil column experiment to ...

Microbial hydrogen sinks in the sand-bentonite backfill material for the deep geological disposal of radioactive waste

Rizlan Bernier-Latmani, Manon Frutschi, Niels Burzan, Aislinn Ann Boylan, Nicolas Louis Maurice Jacquemin, Simiao Wang, Camille Aude Rolland

The activity of subsurface microorganisms can be harnessed for engineering projects. For instance, the Swiss radioactive waste repository design can take advantage of indigenous microorganisms to tackle the issue of a hydrogen gas (H2) phase pressure build ...

Spatially Explicit Linkages Between Redox Potential Cycles and Soil Moisture Fluctuations

Rizlan Bernier-Latmani, Manon Frutschi, Andrea Rinaldo, Paolo Benettin, Mitra Asadollahi, Simiao Wang, Filippo Miele

Reduction-oxidation cycles measured through soil redox potential (Eh) are associated with dynamic soil microbial activity. Understanding changes in the composition of, and resource use by, soil microbial communities requires Eh predictability under shiftin ...

Active anaerobic methane oxidation and sulfur disproportionation in the deep terrestrial subsurface

Rizlan Bernier-Latmani, Manon Frutschi, Emma Bell, Chen Qian

Microbial life is widespread in the terrestrial subsurface and present down to several kilometers depth, but the energy sources that fuel metabolism in deep oligotrophic and anoxic environments remain unclear. In the deep crystalline bedrock of the Fennosc ...

Growth and persistence of an aerobic microbial community in Wyoming bentonite MX-80 despite anoxic in-situ conditions

Rizlan Bernier-Latmani, Manon Frutschi, Roberta Murad Lima, Niels Burzan

Microbial activity has the potential to enhance the corrosion of high-level radioactive waste disposal canisters, which, in the proposed Swiss deep geological repository, will be embedded in bentonite and placed in the Opalinus Clay rock formation (OPA). T ...

Active sulfur cycling in the terrestrial deep subsurface

Rizlan Bernier-Latmani, Manon Frutschi, Emma Bell, Chen Qian

The deep terrestrial subsurface remains an environment where there is limited understanding of the extant microbial metabolisms. At Olkiluoto, Finland, a deep geological repository is under construction for the final storage of spent nuclear fuel. It is th ...

As release under the microbial sulfate reduction during redox oscillations in the upper Mekong delta aquifers, Vietnam: A mechanistic study

Rizlan Bernier-Latmani, Manon Frutschi, Laurent Louis José Charlet

The impact of seasonal fluctuations linked to monsoon and irrigation generates redox oscillations in the subsurface, influencing the release of arsenic (As) in aquifers. Here, the biogeochemical control on As mobility was investigated in batch experiments ...

Colloidal Size and Redox State of Uranium Species in the Porewater of a Pristine Mountain Wetland

Rizlan Bernier-Latmani, Manon Frutschi, Barbora Bártová, Giada Chantal Zünd, Gabrielle Dublet, Ashley Richards Brown

Uranium (U) speciation was investigated in anoxically preserved porewater samples of a natural mountain wetland in Gola di Lago, Ticino, Switzerland. U porewater concentrations ranged from less than 1 mu g/L to tens of mu g/L, challenging the available ana ...

Microbially Mediated Release of As from Mekong Delta Peat Sediments

Rizlan Bernier-Latmani, Manon Frutschi, Yuheng Wang, Karen Elda Viacava Romo, Luca Loreggian, Maria Pilar Asta Andres

Peat layers within alluvial sediments are considered effective arsenic (As) sinks under reducing conditions due to the binding of As(III) to thiol groups in natural organic matter (NOM) and the formation of As-bearing sulfide phases. However, their possibl ...

Biogeochemical Cycling by a Low-Diversity Microbial Community in Deep Groundwater

Rizlan Bernier-Latmani, Manon Frutschi, Louise Julia Balmer, Guillaume Sommer, Emma Bell, Chen Qian

Olkiluoto, an island on the south-west coast of Finland, will host a deep geological repository for the storage of spent nuclear fuel. Microbially induced corrosion from the generation of sulphide is therefore a concern as it could potentially compromise t ...

Phylogenetic comparison of Desulfotomaculum species of subgroup 1a and description of Desulfotomaculum reducens sp.nov

Rizlan Bernier-Latmani, Manon Frutschi

A genome and physiological comparison was made of the type strains of Desulfotomaculum species belonging to subgroup 1a and of 'Desulfotomaculum reducens' strain MI-1. Phenotypically, 'Desulfotomaculum reducens' strain MI-1 can be distinguished from the ot ...

Mobile uranium(IV)-bearing colloids in a mining-impacted wetland

Elena Suvorova Buffat, Rizlan Bernier-Latmani, Manon Frutschi, Yuheng Wang

Tetravalent uranium is commonly assumed to form insoluble species, resulting in the immobilization of uranium under reducing conditions. Here we present the first report of mobile U(IV)-bearing colloids in the environment, bringing into question this commo ...
