Electroenzymatic Cascades for Nitrogen Upgrading: Beyond Ammonia Towards Value‐Added Nitrogen Chemicals

ChemCatChem, Volume 18, Issue 7, 14 April 2026.
This review maps how electroenzymatic cascades that couple nitrogen‐cycle enzymes with C─N bond forming auxilary enzymes, powered by direct electron transfer (DET) or mediated electron transfer (MET), can upgrade N2 and waste nitrogen streams into value‐added amines, amides, amino acids, and other nitrogen‐based chemicals.

Biotic–Abiotic Hybrid Strategies for Photosynthetic Nitrogen Fixation and Green Ammonia Synthesis

ChemistryEurope, Volume 4, Issue 4, April 2026.
Biotic‐abiotic photosynthetic systems integrate light‐harvesting semiconductors with nitrogenase's selective N2 reduction under ambient conditions, offering a sustainable alternative to conventional ammonia synthesis. Advancing rational interface design, efficient energy‐reaction coupling, and system integration is critical to realizing scalable, solar‐

A CRISPR interference system for engineering biological nitrogen fixation

mSystems
A grand challenge for the next century is in facing a changing climate through bioengineering solutions. Biological nitrogen fixation, the globally consequential, nitrogenase-catalyzed reduction of atmospheric nitrogen to bioavailable ammonia, is a vital

A novel bleb-dependent polysaccharide export system in nitrogen-fixing Azotobacter vinelandii subjected to low nitrogen gas levels [PDF]

, 2013
The alginate biofilm-producing bacterium Azotobacter vinelandii aerobically fixes nitrogen by oxygensensitivenitrogenases. Here we investigated the bacterial response to nitrogen/oxygen gas mixtures. A.

NifB and NifEN protein levels are regulated by ClpX2 under nitrogen fixation conditions in Azotobacter vinelandii [PDF]

, 2011
The major part of biological nitrogen fixation is catalysed by the molybdenum nitrogenase that carries at its active site the iron and molybdenum cofactor (FeMo-co).

Rhizobacteria Exopolysaccharide: A Boon in Reclaiming Soil Fertility, Augmenting Plant Growth and Plant Stress Resilience

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Microbial exopolysaccharides (EPS) enhance plant stress tolerance and soil health by improving water retention, nutrient cycling, and resilience to salinity and heavy metals, offering a biodegradable and eco‐friendly alternative to synthetic polymers for sustainable agriculture. ABSTRACT Microbial exopolysaccharides (EPSs) serve multiple industrial and

A Foundation for Advancing Studies of the Biodegradation of Polyethylene Surrogates by Environmental and Model Laboratory Microbes

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
A polyethylene surrogate sample containing paraffin, polywax and polyethylene was exposed to selected microbes identified in this study. This image shows the surface of this surrogate following a six‐week incubation with Rhodococcus jostii. ABSTRACT Polyethylene represents a particularly recalcitrant class of plastics that persist for decades in the ...

Effect of native strains of plant growth promoting rhizobacteria on growth and yield of Isabgol (Plantago ovata)

The Indian Journal of Agricultural Sciences, 2016
An experiment was conducted to evaluate the growth promotion in isabgol (Plantago ovata Forsk.) with native rhizobacteria strains (ISB-2, ISB-5, ISB-8, ISB-9, ISB-10, ISB-125, ISB-15 and ISB-28) isolated from the rhizospheric soils collected from ...

The unphosphorylated EIIA(Ntr) protein represses the synthesis of alkylresorcinols in Azotobacter vinelandii. [PDF]

PLoS ONE, 2015
Upon encystment induction, Azotobacter vinelandii produces the phenolic lipids alkylresorcinols (ARs) that are structural components of the cysts. The enzymes responsible for the ARs synthesis are encoded in the arsABCD operon, whose expression is ...

Regular surface layer of Azotobacter vinelandii [PDF]

Journal of Bacteriology, 1984
Washing Azotobacter vinelandii UW1 with Burk buffer or heating cells at 42 degrees C exposed a regular surface layer which was effectively visualized by freeze-etch electron microscopy. This layer was composed of tetragonally arranged subunits separated by a center-to-center spacing of approximately 10 nm. Cells washed with distilled water to remove an
