The major transformations of nitrogen are nitrogen fixation, nitrification, denitrification, anammox, and ammonification (Figure 1). The transformation of nitrogen into its many oxidation states ...

Because of the scarcity of suitable carbon and energy sources for these organisms, their contribution to global nitrogen fixation rates is generally considered minor. However, a recent study in ...

Such nitrogen fixation, as it is known, is a fundamental limit on plant growth and an essential nutrient for all life. Yet, this critically important cycle remains poorly understood. "We don't ...

Some bacteria found in marine waters can convert nitrogen gas (N2) to ammonia (known as N2 fixation), and thereby supply the marine food web with nitrogen. It has puzzled scientists for years ...

Researchers have developed a simpler pathway, involving a newly known minimum of seven genes that allow the plant cell to ...

An oxygen sensor protein protects the enzymatic machinery of biological nitrogen fixation from serious damage, and its use in ...

There are two primary ways that can happen, one natural and one synthetic. Nitrogen fixation occurs naturally due to the action of microbes that live in nodules on plant roots. These organisms ...

Nitrogen fixation hotspots in Atlantic seaweed Date: August 4, 2023 Source: University of North Carolina at Chapel Hill Summary: A new study examined nitrogen fixation among diazotrophs ...

Research into bacteria strains that are both competitive and efficient in nitrogen fixation and developing plants with those characteristics is the goal of NDSU research started in October 2024.
