Greenhouse Gas Mitigation Potential of Temperate Fen Paludicultures

open access: yesGlobal Change Biology, Volume 31, Issue 8, August 2025.
Peatlands lose their valuable carbon sink function under intensive land use and turn into greenhouse gas (GHG) emission hotspots. This study presents the first full GHG balance dataset for five potential fen paludicultures, measuring CO2, methane, and nitrous oxide emissions using manual and novel automated chambers across a water table gradient in ...

Two Key Ferredoxins for Nitrogen Fixation Have Different Specificities and Biophysical Properties

open access: yesChemistry – A European Journal, Volume 31, Issue 37, July 2, 2025.
Two ferredoxins, FdC and FdN, are collectively essential for the process of nitrogen fixation by the iron nitrogenase in R. capsulatus. We explore the biophysical factors, through spectroscopic and structural characterizations, which determine ferredoxin functionality and pathway specificity. The structure of FdC (PDB: 9I2A) and model of FdN (AF‐D5ARY6)
