How much carbon can the ocean absorb, and what happens to it as the planet warms? Sonya Dyhrman, a microbial oceanographer ...

Because oxygen inhibits nitrogen fixation, most nitrogen-fixing cyanobacteria only fix nitrogen at night, or do it in specialized cells. The lack of photosystem II enables the new microbe to fix ...

Heterocyst differentiation constitutes a pivotal developmental process in filamentous cyanobacteria, allowing these organisms to sidestep the oxygen sensitivity of the nitrogenase enzyme. Under ...

Nitrogen fixation in boreal forests is vital for sustaining ecosystem productivity in environments where soil nitrogen is limited. Moss-cyanobacteria associations, commonly found in species such ...

What emerged was a strain of nitrogen-fixing cyanobacteria that are about 100 times as large as typical photosynthetic ocean bacteria. "They're like basketballs, compared to the pins of light we ...

Jingyu Wang, Nicole D. Wagner, James M. Fulton, J. Thad Scott, Diazotrophs modulate phycobiliproteins and nitrogen stoichiometry differently than other cyanobacteria in response to light and nitrogen ...

This nitrogen-fixing capacity of cyanobacteria played a pivotal role in enhancing plant nutrient uptake and overall growth performance. Characterization of synthesized nanoparticles demonstrated their ...

On land, nitrogen-fixing bacteria are a known quantity, residing in the roots of legumes like peas and beans. While many nitrogen-fixing cyanobacteria have been found in coastal waters, very few ...

Other types of diatoms form associations with nitrogen-fixing cyanobacteria, and these cyanobacteria symbionts can be easily detectable by the bright orange pigment they exhibit when exposed to ...

For their experiments, scientists used a nitrogen-fixing cyanobacteria strain named Anabaena sp. PCC 7938, which previous studies suggested would be able to adapt to Martian conditions.

It was long assumed that cyanobacteria were mainly responsible for fixing nitrogen on early Earth, thus making nitrogen available to the biosphere. Researchers now show that purple sulfur bacteria ...

BROOKINGS, S.D.— The National Science Foundation has selected South Dakota State University to lead a statewide project focused on research surrounding biological nitrogen fixation and its ...
