Enhancement of Nitrogenase Activity in Recombinant Escherichia coli by Replacing Upstream Region of nif Operon from Paenibacillus Species

ChemBioChem, Volume 27, Issue 3, 12 February 2026.
Biological N2 fixation by nitrogenase offers a sustainable alternative to the Haber–Bosch process. Heterologous nitrogenase production in Escherichia coli is a promising strategy. We engineered E. coli with nitrogen fixation (nif) operons from diazotrophic Paenibacillus species.

Modeling of nitrogen fixation and polymer production in the heterotrophic diazotroph Azotobacter vinelandii DJ

Metabolic Engineering Communications, 2020
Nitrogen fixation is an important metabolic process carried out by microorganisms, which converts molecular nitrogen into inorganic nitrogenous compounds such as ammonia (NH3). These nitrogenous compounds are crucial for biogeochemical cycles and for the

Functional Glass‐based Fertilizer Implementing Bacterial Nitrogen Fixation

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT Fertilizers are indispensable in modern agriculture, with >200 Mt of nitrate and mineral fertilizers being consumed globally each year. Sustainable agricultural intensification requires nutrient‐efficient fertilization strategies that avoid environmental damage and preserve finite resources.

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

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.
