Microscopic organism plays crucial role in ocean carbon cycling
Washington: Researchers have said that microscopic organism play a very important role in ocean carbon cycling.
When phytoplankton use carbon dioxide to make new cells, a substantial portion of that cellular material is released into the sea as a buffet of edible molecules collectively called "dissolved organic carbon."
The majority of these molecules are eventually eaten by microscopic marine bacteria, used for energy, and recycled back into carbon dioxide as the bacteria exhale. The amount of carbon that remains as cell material determines the role that ocean biology plays in locking up atmospheric carbon dioxide in the ocean.
Thus, these "recycling" bacteria play an important role in regulating how much of the planet`s carbon dioxide is stored in the oceans. The detailed mechanisms of how the oceans contribute to this global carbon cycle at the microscopic scale, and which microbes have a leadership role in the breakdown process, are complex and convoluted problems to solve.
In the study, Scripps scientists have pinpointed a bacterium that appears to play a dominant role in carbon consumption. Scripps`s Byron Pedler, Lihini Aluwihare, and Farooq Azam found that a single bacterium called Alteromonas could consume as much dissolved organic carbon as a diverse community of organisms.
Pedler said that this was a surprising result because this pool of carbon is comprised of an extremely diverse set of molecules, we believed that many different microbes with complementary abilities would be required to breakdown this material, but it appears that individual species may be pulling more weight than others when it comes to carbon cycling.
The study has been published in the Proceedings of the National Academy of Sciences.
