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.

Regulatory response to a hybrid ancestral nitrogenase in Azotobacter vinelandii [PDF]
Microbiology Spectrum, 2023 Biological nitrogen fixation, the microbial reduction of atmospheric nitrogen to bioavailable ammonia, represents both a major limitation on biological productivity and a highly desirable engineering target for synthetic biology. However, the engineering

Precision control of ammonium release in Azotobacter vinelandii [PDF]
Microbial BiotechnologyThe capture and reduction of atmospheric dinitrogen gas to ammonium can be accomplished through the enzyme nitrogenase in a process known as biological nitrogen fixation (BNF), by a class of microbes known as diazotrophs.

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.
