Electron transfer reactions and their role in soil carbon cycling
Electron transfer reactions are central to the transformation of energy in the environment and play an important role in biogeochemical element cycling. In soils, one of the main drivers of carbon cycling is the activity of organisms that utilize the energ ...
2024Climatic and Ecological Impact of Greenlandic Glacial Outwash Plains
Devis Tuia, Julia Schmale, Nora Bergner, Ianina Altshuler, Gaston Jean Lenczner, Grace Emma Marsh
Warming in the Arctic is occurring at an accelerated rate compared to the rest of the world which is partially driven by ecological and climatic feedback loops. Accelerated glacial and ice sheet retreat in Greenland drives increased development of glacial ...
2023Decision support for the design of integrated biorefineries
A shift from fossil-based energy and products to more sustainable alternatives is essential to reduce greenhouse gas emissions and associated climate change impacts. Biomass represents a promising alternative for providing fuels and carbon-based products w ...
EPFL2023Integrating CO2 mineralization in industrial clusters: the benefits of material and heat integration
François Maréchal, Rafael Amorim Leandro De Castro Amoedo, Julia Granacher, Mouhannad Abou Daher
Curbing and capturing CO2 emissions is no longer enough to cope with the demanding environmental challenges of the coming years. Long-term storage technologies need deployment, to help industrial sectors to reach ambitious emission standards. Mineral carbo ...
2023Photobiology and metabolic interactions in the symbiotic jellyfish Cassiopea
The symbiont-bearing jellyfish Cassiopea live a benthic lifestyle, positioning themselves upside-down on sediments in shallow waters to allow their endosymbiotic algae to photosynthesize in the sunlight. Over the last decades Cassiopea has become increasin ...
EPFL2023Symbiotic nutrient cycling enables the long-term survival of Aiptasia in the absence of heterotrophic food sources
Phototrophic Cnidaria are mixotrophic organisms that can complement their het- erotrophic diet with nutrients assimilated by their algal endosymbionts. Metabolic mod- els suggest that the translocation of photosynthates and their derivatives from the algae ...
2023Water use efficiency: A review of spatial and temporal variability
Water Use Efficiency (WUE) expresses the trade-off between carbon assimilation (or subsequent carbon storage) and water release, two concurrent gas fluxes essential for plant functioning. Here, we review metrics that have been introduced to quantify WUE ac ...
Elsevier2023Towards a negative-emission society
Negative carbon emissions are proved necessary to limit global temperature increase below 1.5C compared to pre-industrial levels. (a) Reducing carbon sources and (b) increasing negative emissions are two effective ways to achieve this goal. (a) involves th ...
EPFL2022Active 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 ...
2022Presence of algal symbionts affects denitrifying bacterial communities in the sea anemone Aiptasia coral model
Anders Meibom, Nils Rädecker, Claudia Isabella Pogoreutz
The coral-algal symbiosis is maintained by a constant and limited nitrogen availability in the holobiont. Denitrifiers, i.e., prokaryotes reducing nitrate/nitrite to dinitrogen, could contribute to maintaining the nitrogen limitation in the coral holobiont ...
