Transformation of Azotobacter vinelandii with plasmid DNA [PDF]

Journal of Bacteriology, 1985
Azotobacter vinelandii cells can be transformed at high frequencies with the broad-host-range plasmids pRK2501, RSF1010, and pGSS15, using a modification of the procedure developed by Page and von Tigerstrom (J. Bacteriol. 139:1058-1061, 1979) for chromosomal DNA-mediated transformation.

Identification of sulfurtransferase enzymes in Azotobacter vinelandii [PDF]

FEBS Letters, 1991
Rhodanese and 3‐mercaptopyruvate sulphurtransferase have been identified in A. vinelandii. Two distinct active fractions of the two sulphurtransferases were obtained after FPLC ion‐exchange chromatography of material partially purified from crude extracts. Rhodanese has been purified to homogeneity, and it consists of one polypeptide chain of M r ca 25

Glucose uptake in Azotobacter vinelandii occurs through a GluP transporter that is under the control of the CbrA/CbrB and Hfq-Crc systems

Scientific Reports, 2017
Azotobacter vinelandii, a strict aerobic, nitrogen fixing bacterium in the Pseudomonadaceae family, exhibits a preferential use of acetate over glucose as a carbon source.

The oxygen‐sensing FixLJ represses nitrogen fixation in Rhodopseudomonas palustris in response to oxygen

mLife, Volume 5, Issue 3, Page 312-324, June 2026.
Abstract Biological nitrogen fixation in symbiotic diazotrophs is subject to oxygen regulation by an oxygen‐sensing FixLJ two‐component system under micro‐oxic conditions. However, it remains unclear whether this mechanism is conserved in free‐living diazotrophs.

Inoculation With Azospirillum brasilense and Bacillus amyloliquefaciens Enhances Tomato Resilience to Severe Water Deficit: A Comprehensive Morpho‐Physiological and Biochemical Analysis

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 ...

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

Enzymatic and microbial routes to bioplastics: The green chemistry frontier of biopolymers

FEBS Open Bio, Volume 16, Issue 4, Page 709-726, April 2026.
Microbial biosynthesis and engineered enzyme platforms are expanding the design space of polyhydroxyalkanoate bioplastics. By combining fermentation, PHA synthase engineering and cell‐free modular systems, tailored biodegradable polymers can be produced with tunable properties, supporting more sustainable materials and future circular bioeconomy ...

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
