Plasmid Transformation of Azotobacter vinelandii OP [PDF]

open access: yesMicrobiology, 1987
Azotobacter vinelandii OP which had been naturally induced to competence by growth in iron- and molybdenum-limited medium was transformed with the broad-host-range cloning vector pKT210. However, the transformation frequency at nearly saturating levels of DNA was 1000-fold lower for pKT210 than for a single chromosomal DNA marker (nif+).

Molecular Mechanisms of Pseudomonas-Assisted Plant Nitrogen Uptake: Opportunities for Modern Agriculture

open access: yesMolecular Plant-Microbe Interactions, 2023
Pseudomonas spp. make up 1.6% of the bacteria in the soil and are found throughout the world. More than 140 species of this genus have been identified, some beneficial to the plant.

Phosphate-limited culture of Azotobacter vinelandii [PDF]

open access: yesJournal of Bacteriology, 1979
Batch cultures of Azotobacter vinelandii grown in phosphate-deficient media were compared with control cultures grown in phosphate-sufficient media. Phosphate limitation was assessed by total cell yield and by growth kinetics. Although cell protein, nucleic acids, and early growth rate were unaffected by phosphate deficiency, cell wall structure ...

Identification of Regulatory Genes and Metabolic Processes Important for Alginate Biosynthesis in Azotobacter vinelandii by Screening of a Transposon Insertion Mutant Library

open access: yesFrontiers in Bioengineering and Biotechnology, 2020
Azotobacter vinelandii produces the biopolymer alginate, which has a wide range of industrial and pharmaceutical applications. A random transposon insertion mutant library was constructed from A.

Structure of the Azotobacter vinelandii surface layer [PDF]

open access: yesJournal 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 ...

Endogenous Encystment of Azotobacter vinelandii [PDF]

open access: yesJournal of Bacteriology, 1969
When young cells of Azotobacter vinelandii are impinged on membrane filters, washed free of carbon substrate, and placed on a mineral salts basal medium, the culture will proceed to encyst although at a slower rate than if n -butanol were supplied as a substrate.

Minimal ATP‐Independent N2‐Reducing Systems Defined by L‐Cluster‐Bound Nitrogenase Assembly Platforms

open access: yesAngewandte Chemie, Volume 138, Issue 24, 8 June 2026.
Association of the L‐cluster with the nitrogenase assembly proteins NifEN (NifENL) or NifB (NifBL) intrinsically endows these proteins with N2‐reducing activity, enabling in vitro N2‐reduction by NifENL and NifBL when supplied with chemical reductants or photoexcited quantum dots while supporting in vivo N2‐fixation in NifENL‐ and NifENL‐expressing ...
