Synergistic interaction between Azotobacter and Pseudomonas bacteria in a growth-stimulating consortium

Foods and Raw Materials
Intensifying agricultural production involves an active use of agrochemicals, which results in disrupted ecological balance and poor product quality. To address this issue, we need to introduce biologized science-intensive technologies.

Two Key Ferredoxins for Nitrogen Fixation Have Different Specificities and Biophysical Properties

Chemistry – A European Journal, Volume 31, Issue 37, July 2, 2025.
Two ferredoxins, FdC and FdN, are collectively essential for the process of nitrogen fixation by the iron nitrogenase in R. capsulatus. We explore the biophysical factors, through spectroscopic and structural characterizations, which determine ferredoxin functionality and pathway specificity. The structure of FdC (PDB: 9I2A) and model of FdN (AF‐D5ARY6)

Assessment of free-living nitrogen fixing microorganisms for commercial nitrogen fixation [PDF]

Ammonia production by Klebsiella pneumoniae is not economical with present strains and improving nitrogen fixation to its theoretical limits in this organism is not sufficient to achieve economic viability. Because the value of both the hydrogen produced

Biological Routes for Biohydrogen Production: A Clean and Carbon‐Free Fuel

Biotechnology Journal, Volume 20, Issue 7, July 2025.
Graphical Abstract and Lay Summary Biological routes for hydrogen (H2) production are mainly classified into four pathways: 1) direct bio‐photolysis, 2) indirect bio‐photolysis, 3) photo‐fermentation, and 4) dark fermentation. Of these pathways, dark fermentation produces the highest levels of H2 production.

Improving the Efficiency of a Bioreactor Equipped With Mixed‐Flow Impellers

Chemical Engineering &Technology, Volume 48, Issue 7, July 2025.
The present work investigated the biological performance of mixed‐flow impellers. To the authors’ knowledge, this is the first experimental study on such impellers in a fermentation process using A. vinelandii, which was chosen as a microorganism due to its high oxygen demand.

Improving substrate properties and foxtail millet growth in gold mine tailings using Azotobacter consortium

Journal of Degraded and Mining Lands Management
Improper disposal of mercury (Hg)-contaminated tailings on agricultural fields can reduce land quality for food production. A pot experiment was conducted to evaluate the effect of the Azotobacter consortium, comprising Azotobacter tropicalis S5, A ...

THE OXALACETATE DECARBOXYLASE OF AZOTOBACTER VINELANDII

Journal of Biological Chemistry, 1949
In 1941 Krampitz and Werkman (1) discovered an enzyme in Micro- coccus lysodeikticus which catalyzed the decarboxylation of oxalacetate. By means of an exchange reaction they were able to demonstrate the in- corporation of isotopic carbon dioxide into the p-carboxyl group of oxal- acetic acid in the presence of this enzyme (2). Similar results were ob-
