Protein Science, Volume 35, Issue 3, March 2026.Abstract Biological nitrogen fixation is the process by which certain bacteria and archaea use the enzyme nitrogenase to reduce atmospheric nitrogen into bioavailable ammonium. Engineering non‐nitrogen‐fixing organisms, like plants, to use nitrogenase could reduce dependency on synthetic fertilizer and mitigate the environmental impacts of industrial ...

Turnover-Dependent Inactivation of the Nitrogenase MoFe-Protein at High pH [PDF]
, 2014 Proton uptake accompanies the reduction of all known substrates by nitrogenase. As a consequence, a higher pH should limit the availability of protons as a substrate essential for turnover, thereby increasing the proportion of more highly reduced forms ...

Genotypic Characterization of Azotobacteria Isolated from Argentinean Soils and Plant-Growth-Promoting Traits of Selected Strains with Prospects for Biofertilizer Production [PDF]
, 2013 The genetic diversity among 31 putative Azotobacter isolates obtained from agricultural and non-agricultural soils was assessed using rep-PCR genomic fingerprinting, and identified to species level by ARDRA and partial 16S rRNA gene sequence analysis ...

Effect of pH on growth and nitrogen fixation of Azotobacter Spp. [PDF]
, 1997 Three species o f Azotobacter were isolated from prawn-cum-paddy fields o f Kerala. These strains were found to have the optimum pH for growth and nitrogen fixation near or slightly above neutrality, i.e., in the pH range o f 7.0 to 8.

The FEBS Journal, Volume 293, Issue 6, Page 1616-1620, March 2026.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
