Direct production of polyhydroxybutyrate and alginate from crude glycerol by Azotobacter vinelandii using atmospheric nitrogen [PDF]

open access: yesScientific Reports, 2022
While biodiesel is drawing attention as an eco-friendly fuel, the use of crude glycerol, a byproduct of the fuel production process, has increasingly become a concern to be addressed.

Isolation and characterization of TayeBlu, a novel bacteriophage of Azotobacter vinelandii [PDF]

open access: yesMicrobiology Spectrum
Soil microbial communities drive global biogeochemical cycles and alter crop yields through nitrogen fixation. As agents of genetic mobility, mortality, and nutrient release, viruses have been shown to influence microbial community structure and activity

Automated Laboratory Growth Assessment and Maintenance of Azotobacter vinelandii

open access: yesCurrent Protocols, 2021
Azotobacter vinelandii (A. vinelandii) is a commonly used model organism for the study of aerobic respiration, the bacterial production of several industrially relevant compounds, and, perhaps most significantly, the genetics and biochemistry of ...

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

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

Enhanced Urea Production in the Diazotroph Azotobacter vinelandii as a Means of Stable Nitrogen Biofertiliser Production [PDF]

open access: yesMicrobial Biotechnology
Diazotrophic 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]

open access: yesScientific 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.
