Summary:
Scientists are now revisiting, and perhaps revising, their thinking about how Archaea, an ancient kingdom of single-celled microorganisms, are involved in maintaining the global balance of nitrogen and carbon. Researchers have discovered the first Archaea known to oxidize ammonia for energy and metabolize carbon dioxide by successfully growing the tentatively named, Nitrosopumilus maritimus, in the lab.

Researchers discovered that a single-celled marine microorganism of the Archaea kingdom may play an important role in global nitrogen and carbon cycling. The new finding was evident after scientists determined what nutrients were needed to keep the organism growing in the laboratory.
