Nitrogen fixation by bacteria occurs in root nodules of nitrogen-fixing trees. This nitrogen fixer, a member of the genus Inga, is growing in a recovering tropical forest in Panama. Trees with the ...

Nitrogen is one of the primary nutrients critical for the survival of all living organisms. Although nitrogen is very abundant in the atmosphere, it is largely inaccessible in this form to most ...

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 ...

Nitrogen fixation is surprisingly high in the ocean's coastal waters and may play a larger role than expected in carbon dioxide uptake, a new study shows. The findings -- based on thousands of samples ...

Corkscrew bacteria in termite guts and natural waters help capture a key element Microbiologists have discovered that a type of bacteria found in termite guts and in fresh and salt water plays a major ...

The top row of images are CARD-FISH images of UCYN-A haptophyte symbiosis in the Bering Sea. The nitrogen fixing cyanobacteria UCYN-A2 are shown in red and the Haptophyte algae host are shown in blue ...

Microbes that provide natural fertilizer to the oceans by 'fixing' nitrogen from the atmosphere into a form useable by other organisms are active in the cold waters of the Bering and Chukchi Seas.
