Genetic diversity of Azotobacter strains isolated from soils by amplified ribosomal DNA restriction analysis [PDF]

, 2014
Strains of Azotobacter mediate in the nitrogen fixation process by reducing of N2 to ammonia. In this study, 50 strains were isolated from different rhizospheric soil in central Iran, by using soil paste-plate method.

Understanding the P‐Cluster of Vanadium Nitrogenase: an EPR and XAS Study of the Holo vs. Apo Forms of the Enzyme

ChemBioChem, Volume 26, Issue 3, February 1, 2025.
The present study brings a combination of biochemical techniques, electron paramagnetic resonance (EPR) spectroscopy and extended X‐ray absorption fine structure (EXAFS) data to help to understand the P‐cluster of nitrogenases, in particular the differences between the holo and apo‐forms of the nitrogenase VFe protein.

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.

Phylogenetic differences in content and intensity of periodic proteins [PDF]

, 2005
Many proteins exhibit sequence periodicity, often correlated with a visible structural periodicity. The statistical significance of such periodicity can be assessed by means of a chi-square-based test, with significance thresholds being calculated from ...

The CBRB regulon: Promoter dissection reveals novel insights into the CbrAB expression network in Pseudomonas putida [PDF]

, 2018
CbrAB is a high ranked global regulatory system exclusive of the Pseudomonads that responds to carbon limiting conditions. It has become necessary to define the particular regulon of CbrB and discriminate it from the downstream cascades through other ...
