"There are more than a billion bacteria in just one litre of seawater. How do
all of these organisms find the energy and nutrients they need to survive?
In the nutrient-rich waters near the surface of the ocean, the primary energy
source is sunlight, which drives photosynthesis, the transformation of light
energy into chemical energy. In much of the open ocean, however, a lack of
nutrients limits photosynthesis, and in the deep ocean it ceases altogether as
there is no sunlight.
Despite this, microbes have found a way to live throughout the vast and dark
ocean. How do they do it?
As we report in
Nature Microbiology, many ocean bacteria in fact gain energy
from two dissolved gases, hydrogen and carbon monoxide, in a process called
chemosynthesis. This hidden but ancient process helps maintain the diversity
and productivity of our oceans."
