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 ...

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.Inoculation with Azospirillum brasilense and Bacillus amyloliquefaciens significantly enhances tomato tolerance to severe water deficit. This strategy boosts agronomic performance, strengthens antioxidant defences and regulates secondary metabolites, providing a sustainable agricultural approach to combat water scarcity and climate change impacts ...

Failure of Azotobacter Vinelandii to Fix Nitrogen in Soil [PDF]
, 1983 It was found that Azotobacter vinelandii grown in a dialyzed soil medium did not fix nitrogen and had a much lower rate of respiration than when grown in Burk's nitrogen-free medium.

Morphogenesis of Cysts in Azotobacter vinelandii [PDF]
Journal of Bacteriology, 1970 Cultures of Azotobacter vinelandii were induced to encystment with β-hydroxybutyrate. The morphological events in the transition from cell to cyst were observed by electron microscopy of thin sections. Upon induction of encystment, cells became rounded and nonmotile.

Plasmids of Azotobacter Vinelandii [PDF]
, 1986 Nineteen laboratory strains of Azotobacter vinelandii and two organisms of the same species isolated from water samples were screened for the presence of plasmid deoxyribonucleic acid (DNA). Three laboratory strains and both organisms isolated from water

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.
