The regulation of the biological fixation of nitrogen in hydric stress conditions varies with the different species of legume plants studied. This was the conclusion of Ruben Ladrera Fernández in his ...

A research team has discovered how the 'Shethna protein II' protects the nitrogen-fixing enzyme nitrogenase from damage. The oxygen sensor protein could help to make nitrogenase usable in ...

The marine nitrogen cycle is crucial to sustaining ocean productivity, with biological nitrogen fixation representing a primary mechanism by which inert atmospheric nitrogen is converted into ...

A new research initiative led by associate professor of bacteriology Betül Kaçar is positioned to transform agriculture and address some of the world’s most pressing ecological and economic challenges ...

Nitrogen is vital for all known life. Yet most nitrogen on Earth is in the atmosphere as di-nitrogen gas, which many organisms can’t use. Fortunately, there are microbes that can tap into this ...

Scientists have transferred a collection of genes into plant-colonizing bacteria that let them draw nitrogen from the air and turn it into ammonia, a natural fertilizer. The work could help farmers ...

THE process of nitrogen fixation is at once one of the most intriguing and elusive of the unsolved problems of microbiology. It is apparently brought about only by the living cells of certain bacteria ...

Forests, grasslands, and other natural areas around the world have access to about a quarter less nitrogen than previously estimated, according to a new study published in Nature. Coauthored by Sarah ...

Fixation of Nitrogen (N2) to Ammonia (NH3) is an essential process for maintaining life on earth. Currently, Ammonia (NH3) production is dominated by the Haber–Bosch process. It operates under ...

Dr. Mariangela Hungria's pioneering research on soil bacteria has revolutionized Brazilian agriculture. For over 40 years, ...

A small helper for big tasks: an oxygen sensor protein protects the enzymatic machinery of biological nitrogen fixation from serious damage. Its use in biotechnology could help to reduce the use of ...
