"Space" advocates, on the other hand, believe that Tricho physically separates the carbon and nitrogen fixation processes in a kind of "division of labor."
Tricho is a single-cell organism that ...
... were actively fixing nitrogen, and sharing it with their bacterial neighbors.
"This is the first time that nitrogen fixation has been documented within methane-oxidizing archaea," Dekas says.
...
... these plant species and puts them at a competitive advantage, despite the energetic cost of nitrogen fixation. It's really quite striking how simple the economics of nitrogen fixation fall out, once ...
An intriguing discovery could overturn present thinking about the role of shelf seas such as the English Channel and North Sea in global nitrogen budgets.
How marine microbe Trichodesmium fixes nitrogen and carbon dioxide apparently at the same time has long puzzled scientists. Using NanoSIMS imaging technology, this study supports the theory that the ...
... nitrogen use or acquisition: photosynthetic tissue allocation, photosynthetic nitrogen use efficiency, nitrogen fixation, nitrogen-leaching losses, gross nitrogen mineralization and plant nitrogen ...
... by a diatom – a type of phytoplankton – the cells of which play host to another nitrogen-fixing cyanobacterium called Richella intracellularis, with Trichodesmium apparently playing second fiddle.

In looking forward to the next Green Revolution, researchers have been carefully examining the role of nitrogen fixation in delivering successful crops around the globe.
... . The primary aim of this project, backed by the Austrian Science Fund FWF, is to compare methods for determining nitrogen fixation levels and their application under conditions of drought stress.
... and large-scale oceanic circulation control the availability of a crucial nutrient, nitrogen, in the Atlantic. Their findings have potentially important implications for understanding global climate, ...
... the way circadian rhythms govern global gene expression in Cyanothece, a type of cyanobacterium (blue-green alga) known to cycle between photosynthesis during the day and nitrogen fixation at night.
... from the atmosphere to a form that can be used by other living organisms, a process referred to as "nitrogen-fixation." The researchers showed that this natural fertilization process appears to be ...
... is, outside of an organism. Ten years ago, working with nitrogen-fixation systems, Dean's lab was the first to discover ISC proteins. Now Dean's students, Raulfs and O' ...
