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.

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 ...

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 ...

Evaluation of the Efficacy of Two New Biotechnological-Based Freeze-Dried Fertilizers for Sustainable Fe Deficiency Correction of Soybean Plants Grown in Calcareous Soils

Frontiers in Plant Science, 2019
Currently, fertilization with synthetic chelates is the most effective agricultural practice to prevent iron (Fe) deficiencies in crops, especially in calcareous soils. Because these compounds are not biodegradable, they are persistent in the environment,

Structure of the Azotobacter vinelandii surface layer [PDF]

Journal of Bacteriology, 1987
Electron microscopy of the Azotobacter vinelandii tetragonal surface array, negatively stained with ammonium molybdate in the presence of 1 mM calcium chloride, showed an apparent repeat frequency of 12 to 13 nm. Image processing showed dominant tetrad units alternating with low-contrast cruciform structures formed at the junction of slender linkers ...

Predicting compatibility between ferredoxins and the Fe protein of nitrogenase using in silico protein modeling

Protein Science, Volume 35, Issue 3, March 2026.
Abstract Biological nitrogen fixation is the process by which certain bacteria and archaea use the enzyme nitrogenase to reduce atmospheric nitrogen into bioavailable ammonium. Engineering non‐nitrogen‐fixing organisms, like plants, to use nitrogenase could reduce dependency on synthetic fertilizer and mitigate the environmental impacts of industrial ...
