Modeling of nitrogen fixation and polymer production in the heterotrophic diazotroph Azotobacter vinelandii DJ [PDF]

open access: yesMetabolic Engineering Communications, 2020
Nitrogen fixation is an important metabolic process carried out by microorganisms, which converts molecular nitrogen into inorganic nitrogenous compounds such as ammonia (NH3). These nitrogenous compounds are crucial for biogeochemical cycles and for the

Synthesis, Structure, and Properties of Polyhydroxybutyrate Derived from Azotobacter Vinelandii N-15. [PDF]

open access: yesChemistryOpen
The 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

Genetic and Biochemical Analysis of the Azotobacter vinelandii Molybdenum Storage Protein [PDF]

open access: yesFrontiers in Microbiology, 2019
The N2 fixing bacterium Azotobacter vinelandii carries a molybdenum storage protein, referred to as MoSto, able to bind 25-fold more Mo than needed for maximum activity of its Mo nitrogenase.

Azotobacter vinelandii as a Nitrogen-Negative Chassis for Bio-Oil and Bio-Wax Production of Heterologous and Native Lipids. [PDF]

open access: yesMicrobiologyopen
Strains of the nitrogen‐fixing microbe Azotobacter vinelandii were restructured to remove competing metabolites, resulting in the hyper accumulation of the native lipid alkylresorcinol, visible as large inclusions within the cell. ABSTRACT The biosynthetic production of energy‐dense petrochemical substitutes is an important goal to address ...

Quantification of ploidy in proteobacteria revealed the existence of monoploid, (mero-)oligoploid and polyploid species [PDF]

open access: yes, 2011
Bacteria are generally assumed to be monoploid (haploid). This assumption is mainly based on generalization of the results obtained with the most intensely studied model bacterium, Escherichia coli (a gamma-proteobacterium), which is monoploid during ...

Optımızatıon of Condıtıons for the Productıon of Indole Acetıc Acıd by Azotobacter spp.

open access: yesUMYU 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.

A Closer Look at the FeS Heme Bonds in Azotobacter vinelandii Bacterioferritin: QM/MM and Local Mode Analysis. [PDF]

open access: yesJ Comput Chem
Using the QM/MM method, we analyzed the strength of FeS bonds in heme groups of oxidized and reduced forms of bacterioferritin. The strength of FeS bonds was correlated with bond length, energy density at bond critical point, and charge difference between F and S atoms.
