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 ...

Defining the regulatory mechanisms of sigma factor RpoS degradation in Azotobacter vinelandii and Pseudomonas aeruginosa

Molecular Microbiology, Volume 120, Issue 1, Page 91-102, July 2023., 2023
In bacteria belonging to the Pseudomonadaceae family, such as Azotobacter vinelandii and Pseudomonas aeruginosa, the regulation of proteolysis of the alternative sigma factor RpoS remains poorly understood. Here, we demonstrate that during the exponential phase of growth, two proteins (RssB and RssC) are necessary for the degradation of RpoS by the ...

Evidence that the PatB (CnfR) factor acts as a direct transcriptional regulator to control heterocyst development and function in the cyanobacterium Nostoc PCC 7120

Molecular Microbiology, Volume 119, Issue 4, Page 492-504, April 2023., 2023
PatB: A pleiotropic transcriptional regulator controlling diazotrophy and cell speciation in multicellular cyanobacteria. Abstract Under nitrogen‐limiting conditions, the filamentous cyanobacterium Nostoc PCC7120 differentiates nitrogen‐fixing heterocysts at semi‐regular intervals along filaments generating a periodic pattern of two distinct cell types.

Azotobacter Population, Soil Nitrogen and Groundnut Growth in Mercury-contaminated Tailing Inoculated with Azotobacter [PDF]

, 2018
Gold mine tailing in Buru island, Maluku Province, Indonesia contains high level of mercury but low in carbon and plant nutrients. Revegetation in such condition needs certain soil treatment which is suitable for plant growth. The objective of pot trials

Nontraditional production additives fail to improve potato yield and economic return

Agronomy Journal, Volume 115, Issue 2, Page 801-816, March/April 2023., 2023
Abstract Manufacturers of nontraditional crop additives may claim products will enhance yield and improve economic return, yet many offer only grower testimonials for product validation rather than unbiased, peer‐reviewed research. If the products do not perform as described, they may serve to reduce grower revenue.

Evaluating the growth performance of Two Azotobactor spp. In liquid glucose broth and tryptic peptone broth as inoculum for the production of bio-fertilizers

Tropical Agricultural Research, 2017
Biofertilizers with Azotobacter spp. releases available nitrogen to the plant rhizosphere. A media that yield a high viable inoculum cell count in a shorter incubation period is important for commercial production of biofertilizers.

Gonidium Production in Azotobacter chroococcum [PDF]

Journal of General Microbiology, 1967
SUMMARY: Electron microscopy of sections of Azotobacter chroococcum show that gonidia c. 0.05 μ are produced by or near the cell envelopes, increasing in size to c. 1 μ and filling the lumen of the cell before release, which occurs by rupture of the envelopes.
