Enabling Biological Nitrogen Fixation for Cereal Crops in Fertilized Fields.
ACS Synthetic Biology, 2021 Agricultural productivity relies on synthetic nitrogen fertilizers, yet half of that reactive nitrogen is lost to the environment. There is an urgent need for alternative nitrogen solutions to reduce the water pollution, ozone depletion, atmospheric ...

Regulatory response to a hybrid ancestral nitrogenase in Azotobacter vinelandii
Microbiology Spectrum, 2023 Biological nitrogen fixation, the microbial reduction of atmospheric nitrogen to bioavailable ammonia, represents both a major limitation on biological productivity and a highly desirable engineering target for synthetic biology. However, the engineering

Isolation, identification and characterization of nitrogen fixing endophytic bacteria and their effects on cassava production [PDF]
PeerJ, 2022 Background Cassava (Manibot esculenta Crantz) is one of the most important among tuber crops. The amount of nitrogen fertilizer used for cassava production is relatively high (400 kg ha−1), but there are few studies on biological nitrogen fixation in ...

Symbiotic Nitrogen Fixation and the Challenges to Its Extension to Nonlegumes [PDF]
, 2016 Access to fixed or available forms of nitrogen limits the productivity of crop plants and thus food production. Nitrogenous fertilizer production currently represents a significant expense for the efficient growth of various crops in the developed world.

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;
