Microbial ecology: Metabolism of the deep

Christa Schleper1

Top

Certain microorganisms from the domain Archaea seem to be big players in the marine carbon and nitrogen cycles. A study linking their abundance in the deep sea to their likely metabolic profile refines this view.

The deep ocean covers two-thirds of our planet and teems with microbial life. Understanding the roles of deep-sea microbial communities is therefore essential for understanding global biogeochemical cycling, which in turn is pivotal for all other forms of life.
