Root inoculation with Azotobacter chroococcum 76A enhances tomato plants adaptation to salt stress under low N conditions

BMC Plant Biology, 2018
The emerging roles of rhizobacteria in improving plant nutrition and stress protection have great potential for sustainable use in saline soils. We evaluated the function of the salt-tolerant strain Azotobacter chroococcum 76A as stress protectant in an ...

Hurdles to overcome to achieve biostimulant‐driven, low chemical input crop production

PLANTS, PEOPLE, PLANET, EarlyView.
Crop production requires considerable chemical inputs that result in significant greenhouse gas emissions and other environmental costs. Biostimulants are natural agents, such as microorganisms or seaweed, applied to plants and soil to stimulate plant growth and reduce chemical inputs. Biostimulant use is rapidly increasing globally, but hurdles remain,

Diauxic growth in Azotobacter vinelandii [PDF]

Journal of Bacteriology, 1985
Azotobacter vinelandii exhibited diauxie when grown in a medium containing both acetate and glucose as carbon sources. Acetate was used as the primary carbon source during the acetate-glucose diauxie. Uptake of acetate was constitutively expressed during both diauxic phases of growth. Induction of the glucose uptake system was inhibited in the presence

Effect of Azotobacter in Association with Other Nutrient Sources on Soil Properties in Maize (Zea mays) Field of Nawalpur, Nepal

Turkish Journal of Agriculture: Food Science and Technology
The modern intensive agriculture system relies on the heavy use of chemical fertilizers for food production, neglecting the health of the soil. To explore the alternative nutrient source provided by Azotobacter, a free-living nitrogen-fixing bio ...

Structural analysis of the NifL‐NifA complex reveals the molecular basis of anti‐activation of nitrogen fixation gene expression in Azotobacter vinelandii

The FEBS Journal, EarlyView.
Using cryo‐EM combined with biochemical and genetic approaches, we mapped the interaction surface between NifL and NifA to gain insights into the regulation of nitrogen fixation genes in A. vinelandii. Our findings suggest that NifL, a homolog of histidine kinases lacking phosphorylation activity, evolved to act as a steric block of NifA activity ...

Iron Homeostasis in Azotobacter vinelandii

Biology, 2023
Iron is an essential nutrient for all life forms. Specialized mechanisms exist in bacteria to ensure iron uptake and its delivery to key enzymes within the cell, while preventing toxicity. Iron uptake and exchange networks must adapt to the different environmental conditions, particularly those that require the biosynthesis of multiple iron proteins ...

Enhanced Lipid Production in Chlamydomonas reinhardtii by Co-culturing With Azotobacter chroococcum

Frontiers in Plant Science, 2018
The green algae, Chlamydomonas reinhardtii, is one of the model species used to study lipid production, although research has focused on nitrogen-deficient cultures, that inhibit the development of biomass by C. reinhardtii and limit lipid production. In

Unlocking nitrogen regulation: structural insights into the NifL‐NifA complex and prospects for engineered diazotrophs

The FEBS Journal, EarlyView.
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

The Efficiency of Maize and Common Bean Intercropping Using Economic, Competitive, and Biological Indices for a Sustainable Production

Legume Science, Volume 8, Issue 1, March 2026.
ABSTRACT Intercropping is an effective method for resource utilization that typically enhances crop yields compared with monoculture. This study was conducted using split plot in a randomized complete block design with three replications over the 2022–2023 years.

Biosorption of Chromium by Living Cells of Azotobacter S8, Bacillus subtilis and Pseudomonas aeruginosa using Batch System Reactor

Journal of Ecological Engineering, 2019
Chromium in wastewater is classified as one of the dangerous contaminants that require further treatment before being discharged to water body. The concentration of chromium in water body, especially river, has increased as many industries utilize ...
