Response of Sunflower Yield and Phytohormonal Changes to Azotobacter,Azospirillum,Pseudomonas and Animal Manure in a Chemical Free Agroecosystem [PDF]

, 2011
There are new trends in agriculture to move toward the low input systems with the lower application of chemical fertilizers. To reach this goal, different methods, such as the application of biofertilizers, may be used.

How many metals does it take to fix N2? A mechanistic overview of biological nitrogen fixation [PDF]

, 2006
During the process of biological nitrogen fixation, the enzyme nitrogenase catalyzes the ATP-dependent reduction of dinitrogen to ammonia. Nitrogenase consists of two component metalloproteins, the iron (Fe) protein and the molybdenum-iron (MoFe) protein;

Minimal ATP‐Independent N2‐Reducing Systems Defined by L‐Cluster‐Bound Nitrogenase Assembly Platforms

Angewandte Chemie International Edition, EarlyView.
Association of the L‐cluster with the nitrogenase assembly proteins NifEN (NifENL) or NifB (NifBL) intrinsically endows these proteins with N2‐reducing activity, enabling in vitro N2‐reduction by NifENL and NifBL when supplied with chemical reductants or photoexcited quantum dots while supporting in vivo N2‐fixation in NifENL‐ and NifENL‐expressing ...

Production of bacterial cellulose by Acetobacter okinawensis AC2 and its application as a bioadsorbent for azo dye removal

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Bacterial cellulose (BC) is a naturally occurring polysaccharide that has attracted considerable interest in various fields, including biological and biomedical applications, due to its biodegradability, biocompatibility, high degree of crystallinity, and outstanding physicochemical characteristics. It is widely used in several industries such

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

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 ...
