Nitrogenaseless Mutants of Azotobacter vinelandii [PDF]

Proceedings of the National Academy of Sciences, 1970
Mutants of Azotobacter which grow normally on excess ammonia under a variety of conditions and which grow slowly or not at all on atmospheric nitrogen have been isolated. Extracts of these strains have low or no detectable nitrogenase activity. There are three classes of mutants. Cell-free preparations of members of the first class possess

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

Frontiers 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.

Gene dosage analysis in Azotobacter vinelandii. [PDF]

Genetics, 1992
Abstract For more than a decade, Azotobacter vinelandii has been considered a polyploid bacterium on the basis of physical studies of chromosome size and DNA content per cell. However, as described in the present work, many genetic operations can be performed in A. vinelandii without the constraints expected in a polyploid bacterium: (i)

Evidence That the P\u3csub\u3ei\u3c/sub\u3e Release Event Is the Rate-Limiting Step in the Nitrogenase Catalytic Cycle [PDF]

, 2016
Nitrogenase reduction of dinitrogen (N2) to ammonia (NH3) involves a sequence of events that occur upon the transient association of the reduced Fe protein containing two ATP molecules with the MoFe protein that includes electron transfer, ATP hydrolysis,

Gac two-component system in Pseudomonas syringae pv. tabaci is required for virulence but not for hypersensitive reaction [PDF]

, 2008
Pseudomonas syringae pv. tabaci 6605 causes wildfire disease on host tobacco plants. To investigate the regulatory mechanism of the expression of virulence, Gac two-Component system-defective mutants, Delta gacA and Delta gacS, and a double mutant, Delta

Chemotactic Behavior of Azotobacter vinelandii [PDF]

Applied and Environmental Microbiology, 1991
Chemotaxis was exhibited by Azotobacter vinelandii motile cells. Exposure of cells to sudden increases in attractant concentration suppressed the frequency of tumbling and resulted in smooth swimming. Cells responded chemotactically to a chemical gradient produced during metabolism.

Unlocking nitrogen regulation: structural insights into the NifL‐NifA complex and prospects for engineered diazotrophs

The FEBS Journal, EarlyView.
The urgent need for sustainable agriculture places biological nitrogen fixation at the forefront of current biotechnological research. Plant growth‐promoting rhizobacteria play crucial roles in agriculture by enhancing nutrient absorption, regulating hormonal balance, and providing reduced nitrogen to plants. Among these, diazotrophic bacteria, such as

Functional Nitrogenase Cofactor Maturase NifB in Mitochondria and Chloroplasts of Nicotiana benthamiana

mBio, 2022
Engineering plants to synthesize nitrogenase and assimilate atmospheric N2 will reduce crop dependency on industrial N fertilizers. This technology can be achieved by expressing prokaryotic nitrogen fixation gene products for the assembly of a functional

The Prebiotic and Techno‐Functional Potential of Microbial Exopolysaccharides for Human Health and Food Systems

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 2, March 2026.
ABSTRACT Microbial exopolysaccharides (EPS) represent a diverse class of biopolymers holding considerable promise as functional food ingredients. This review analyzes the dual function of microbial EPS as a candidate for prebiotic agents and techno‐functional additives.
