Reduction of Substrates by Nitrogenases
Chemical Reviews, 2020 Nitrogenase is the enzyme that catalyzes biological N2 reduction to NH3. This enzyme achieves an impressive rate enhancement over the uncatalyzed reaction. Given the high demand for N2 fixation to support food and chemical production and the heavy reliance of the industrial Haber-Bosch nitrogen fixation reaction on fossil fuels, there is a strong need ...

Serpentine Biocrust Microbes Maintain Nitrogen Cycling Under Drought and Heavy Metal Stress
Ecological Research, Volume 41, Issue 5, September 2026.This study highlights the complex interplay between soil geochemistry and moisture availability in shaping microbial communities within wetter and drier serpentine and non‐serpentine biological soil crusts. It demonstrates that both factors influence the structure of nitrogen‐cycling microbial communities and the processes they mediate.

Chimeric Interaction of Nitrogenase‐Like Reductases with the MoFe Protein of Nitrogenase
ChemBioChem, 2020 AbstractThe engineering of transgenic organisms with the ability to fix nitrogen is an attractive possibility. However, oxygen sensitivity of nitrogenase, mainly conferred by the reductase component (NifH)2, is an imminent problem. Nitrogenase‐like enzymes involved in coenzyme F430 and chlorophyll biosynthesis utilize the highly homologous reductases ...

Plant, Cell &Environment, Volume 49, Issue 9, Page 6396-6412, September 2026.ABSTRACT Plant growth–promoting bacteria can enhance plant performance under nutrient limitation, yet the underlying plant molecular responses remain incompletely resolved. We investigated growth promotion by Pseudomonas koreensis in Brachypodium distachyon under contrasting nitrogen (N) regimes using time‐resolved phenotyping, elemental analysis ...

Structural basis for the conformational protection of nitrogenase from O2 [PDF]
Structural DynamicsThe low reduction potentials required for the reduction of dinitrogen (N2) render metal-based nitrogen-fixation catalysts vulnerable to irreversible damage by dioxygen (O2).

Aggregate, Volume 7, Issue 8, August 2026.Bioinorganic hybrids show promise for solar‐to‐chemical conversion, yet are limited by poor light absorption and charge separation. A plasmonic biohybrid (CuS/CdS@yeast), featuring an intracellular S‐scheme heterojunction to achieve efficient electron‐hole separation, is fabricated via in‐situ mineralization for wide‐spectrum solar‐to‐chemical ...

New Zealand Journal of Agricultural Research, Volume 69, Issue 4, August 2026.Bacteria of the genus Azospirillum have been used to mitigate negative effects of drought stress. Since there is few information on interaction of new strains of A. brasilense and soil water status, we evaluated the effects of coinoculation of A. brasilense strains (Ab‐V5/Ab‐V6 and HM053) on soybean plants grown either with (40% of field capacity) or ...

A Non‐Covalent [4Fe–4S]/[2Fe] Interface in HydF Guides [FeFe]‐Hydrogenase Maturation
Angewandte Chemie, Volume 138, Issue 29, 13 July 2026.Bridged or not? 57Fe NRVS reveals a non‐covalent, electronically coupled interaction between the HydF [4Fe–4S] cluster and the [2Fe] precursor. Boltz‐2 structure predictions suggest that the cubane organizes lipoate‐dependent Hmet chemistry, positioning intermediates for assembly of the CH2–NH–CH2 bridge during H‐cluster biosynthesis.

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 8, Page 1632-1642, August 2026.Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...
