Advancements in Alginate‐Based Biomaterials for Enhanced Skin Regeneration: A Comprehensive Review

International Journal of Polymer Science, Volume 2026, Issue 1, 2026.
Alginate, a naturally occurring polysaccharide composed of β‐d‐mannuronate (M) and α‐l‐guluronate (G), has attracted widespread attention for skin regeneration applications due to its exceptional biocompatibility, biodegradability, and tunable physicochemical properties. Beyond its traditional role in maintaining a moist wound environment and providing

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 ...

Oxygen transfer rate during the production of alginate by Azotobacter vinelandii under oxygen-limited and non oxygen-limited conditions [PDF]

, 2011
Background The oxygen transfer rate (OTR) and dissolved oxygen tension (DOT) play an important role in determining alginate production and its composition; however, no systematic study has been reported about the independent influence of the OTR and DOT.

Chemotactic Behavior of Azotobacter vinelandii [PDF]

Applied and Environmental Microbiology, 1991
Chemotaxis was exhibited by Azotobacter vinelandii motile cells. Exposure of cells to sudden increases in attractant concentration suppressed the frequency of tumbling and resulted in smooth swimming. Cells responded chemotactically to a chemical gradient produced during metabolism.

Molecular Mechanisms of Plant Growth–Promoting Rhizobacteria (PGPR) in Biofertilization and Disease Suppression of Crops

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
Plant growth–promoting rhizobacteria (PGPR) are beneficial soil bacteria that colonize the rhizosphere and enhance plant growth through direct and indirect mechanisms, including nutrient solubilization, phytohormone production, suppression of phytopathogens, and activation of plant defense mechanisms.

Key factors affecting ammonium production by an Azotobacter vinelandii strain deregulated for biological nitrogen fixation

Microbial Cell Factories, 2020
Background The obligate aerobe Azotobacter vinelandii is a model organism for the study of biological nitrogen fixation (BNF). This bacterium regulates the process of BNF through the two component NifL and NifA system, where NifA acts as an activator ...

Ferritins: furnishing proteins with iron [PDF]

, 2016
Ferritins are a superfamily of iron oxidation, storage and mineralization proteins found throughout the animal, plant, and microbial kingdoms. The majority of ferritins consist of 24 subunits that individually fold into 4-α-helix bundles and assemble in ...

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
