Enhanced Urea Production in the Diazotroph Azotobacter vinelandii as a Means of Stable Nitrogen Biofertiliser Production [PDF]
Microbial BiotechnologyDiazotrophic microbes capture atmospheric nitrogen and convert it into ammonia using the enzyme nitrogenase in a process that provides much of the fixed nitrogen that is required to sustain life in the biosphere.

A critical role of an oxygen-responsive gene for aerobic nitrogenase activity in Azotobacter vinelandii and its application to Escherichia coli [PDF]
Scientific Reports, 2022 Since nitrogenase is irreversibly inactivated within a few minutes after exposure to oxygen, current studies on the heterologous expression of nitrogenase are limited to anaerobic conditions.

Phasins PhbP2 and PhbP3 Are Involved in the Depolymerization of Polyhydroxybutyrate in Azotobacter vinelandii. [PDF]
J Basic MicrobiolABSTRACT Polyhydroxybutyrate (PHB) is a natural polyester synthesized and stored intracellularly as cytoplasmic granules, serving as a carbon and energy reserve in certain bacteria. These granules are surrounded by a variety of proteins, including those directly involved in PHB metabolism—both in its synthesis and degradation—as well as a group of non ...

Structural analysis of the NifL-NifA complex reveals the molecular basis of anti-activation of nitrogen fixation gene expression in Azotobacter vinelandii. [PDF]
FEBS JUnderstanding the molecular basis of nitrogen fixation is essential for engineering bacteria that fulfill the nitrogen demand of crop plants, reducing our reliance on synthetic nitrogen fertilizers. The bacterial two‐component system comprising the anti‐activator protein (NifL) and the Nif‐specific transcriptional activator (NifA) controls the nitrogen

Synthesis, Structure, and Properties of Polyhydroxybutyrate Derived from Azotobacter Vinelandii N-15. [PDF]
ChemistryOpenThe bacterium Azotobacter vinelandii N15 synthesizes polyhydroxybutyrate (PHB) from sugar production waste. The study reveals the molecular composition, crystallinity, and thermal behavior of the synthesized biopolymer. Mechanical tests demonstrated high tensile strength and relatively low elongation at break. These properties highlight PHB's potential

Optımızatıon of Condıtıons for the Productıon of Indole Acetıc Acıd by Azotobacter spp.
UMYU Journal of Microbiology Research, 2023 Azotobacter spp. are known for their ability to fix nitrogen into the soil non-symbiotically. Their activities can be enhanced through the provision of optimum cultural conditions. Hence, this study aimed to isolate Azotobacter spp.

Plasmids of Azotobacter vinelandii [PDF]
Journal of Bacteriology, 1988 Four laboratory strains and two isolates of Azotobacter vinelandii were found to contain plasmids. Twenty-five laboratory strains which could fix nitrogen did not have free, covalently closed circular plasmid DNA. The plasmids varied in size from 9 to 52 megadaltons, and each strain yielded only one plasmid. No discernible differences in ability to fix

Phospholipids of Azotobacter vinelandii [PDF]
Journal of Bacteriology, 1969 Analyses of resting cells of Azotobacter vinelandii revealed that numerous phospholipids were present that did not concentrate in the membranous R 3 fraction which carried out electron transport function.

Diauxic growth in Azotobacter vinelandii [PDF]
Journal of Bacteriology, 1985 Azotobacter vinelandii exhibited diauxie when grown in a medium containing both acetate and glucose as carbon sources. Acetate was used as the primary carbon source during the acetate-glucose diauxie. Uptake of acetate was constitutively expressed during both diauxic phases of growth. Induction of the glucose uptake system was inhibited in the presence
