Metabolic Performance and Fate of Electrons during Nitrate-Reducing Fe(II) Oxidation by the Autotrophic Enrichment Culture KS Grown at Different Initial Fe/N Ratios
Autotrophic nitrate-reducing Fe(II)-oxidizing (NRFeOx) microorganisms fix CO2 and oxidize Fe(II) coupled to denitrification, influencing carbon, iron, and nitrogen cycles in pH-neutral, anoxic environments. However, the distribution of electrons from Fe(II ...
AMER SOC MICROBIOLOGY2023Excess labile carbon promotes diazotroph abundance in heat-stressed octocorals
Nitrogen limitation is the foundation of stable coral-algal symbioses. Diazotrophs, prokaryotes capable of fixing N-2 into ammonia, support the productivity of corals in oligotrophic waters, but could contribute to the destabilization of holobiont function ...
ROYAL SOC2023High plasticity of nitrogen fixation and denitrification of common coral reef substrates in response to nitrate availability
Nils Rädecker, Hal Hunt Jones II
Nitrogen cycling in coral reefs may be affected by nutrient availability, but knowledge about concentration-dependent thresholds that modulate dinitrogen fixation and denitrification is missing. We determined the effects of different nitrate concentrations ...
2021Toward Functional Type III [Fe]-Hydrogenase Biomimics for H2 Activation: Insights from Computation
Xile Hu, Matthew Wodrich, Kevin Alexander Murray
The chemistry of [Fe]-hydrogenase has attracted significant interest due to its ability to activate molecular hydrogen. The intriguing properties of this enzyme have prompted the synthesis of numerous small molecule mimics aimed at activating H2. Despite c ...
