Liebig Review: Legume–Rhizobium Symbiosis Under Selenium Fertilization: A Unique Dual Function in the Plant–Soil System

Journal of Plant Nutrition and Soil Science, Volume 188, Issue 6, Page 861-872, December 2025.
ABSTRACT Background Selenium (Se) plays a vital role as a beneficial element in promoting the production of leguminous plants. It influences legume quality by improving crop nutritive value and contributing to human and animal health. Literature Review This review is timely, as there are gaps in understanding Se–rhizobia interactions in legumes, which ...

Glucose uptake in Azotobacter vinelandii occurs through a GluP transporter that is under the control of the CbrA/CbrB and Hfq-Crc systems

Scientific Reports, 2017
Azotobacter vinelandii, a strict aerobic, nitrogen fixing bacterium in the Pseudomonadaceae family, exhibits a preferential use of acetate over glucose as a carbon source.

Plastic Type and Condition Have Minimal Impact on Associated Marine Biofilm Communities

Environmental Microbiology, Volume 27, Issue 12, December 2025.
Plastics serve as a novel surface for microbial colonisation, yet their ecological functioning remains poorly understood. Here, we characterise microbial communities colonising plastic in the marine environment over time using a multi‐omics approach, highlighting previously reported plastic‐degrading taxa and the degradation potential within these ...

A CRISPR interference system for engineering biological nitrogen fixation

mSystems
A grand challenge for the next century is in facing a changing climate through bioengineering solutions. Biological nitrogen fixation, the globally consequential, nitrogenase-catalyzed reduction of atmospheric nitrogen to bioavailable ammonia, is a vital

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.

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 ...

Regular surface layer of Azotobacter vinelandii [PDF]

Journal of Bacteriology, 1984
Washing Azotobacter vinelandii UW1 with Burk buffer or heating cells at 42 degrees C exposed a regular surface layer which was effectively visualized by freeze-etch electron microscopy. This layer was composed of tetragonally arranged subunits separated by a center-to-center spacing of approximately 10 nm. Cells washed with distilled water to remove an

Deserts, Rivers, Pools, and Billabongs: Water Features of the Nitrogenase Proteins, and their Functions

ChemBioChem, Volume 26, Issue 21, November 8, 2025.
In the protein surrounding the active site of nitrogenase there is a large anhydrous desert, traversed by two watercourses necessary for the enzyme to convert N2 to NH3. Various pools exist, but their water seems to be stagnant. This review examines the occurrence and function of water inside the protein that contains the catalytic site of the enzyme ...
