OSU The oxygen-rich surface waters of the world’s major oceans are supersaturated with methane – a powerful greenhouse gas that is roughly 20 times more potent than carbon dioxide – yet little is known about the source of this methane. Now a new study by researchers at Oregon State University demonstrates the ability of some strains of the oceans’ most abundant organism – SAR11 – to generate methane as a byproduct of breaking down a compound for its phosphorus. Results...

Oceans Have Been The Stage For Earth's Longest Ongoing Battle Between Bacteria And A Virus

April Flowers for redOrbit.com - Your Universe Online A new study led by Oregon State University reveals that the greatest battle in Earth's history has been going on for hundreds of millions of years. And the battle, which no one knew existed until now, is far from over. The findings of this study were published in a recent issue of Nature. On one side of the battle lines stands SAR11, a bacterium that´s the most abundant organism in the oceans, surviving where most other cells...

Much as an anthropologist can study populations of people to learn about their physical attributes, their environs and social structures, some marine microbiologists read the genome of microbes to glean information about the microbes themselves, their environments and lifestyles. Using a relatively new methodology called comparative population genomics, these scientists compare the entire genomes of different populations of the same microbe to see which genes are "housekeeping" or core genes...

Astrobiology Magazine -- Scientists at Oregon State University have successfully cultured in a laboratory a microorganism with a gene for an alternate form of photochemistry an advance that may ultimately help shed light on the ecology of the world's oceans. The microorganism is SAR11, the smallest free living cell known and probably the most abundant organism in the seas. By being able for the first time to study the SAR11 "proteorhodopsin" gene in a laboratory, researchers will be able to...

CORVALLIS, Ore. -- Researchers at Oregon State University and Diversa Corporation have discovered that the smallest free-living cell known also has the smallest genome, or genetic structure, of any independent cell - and yet it dominates life in the oceans, thrives where most other cells would die, and plays a huge role in the cycling of carbon on Earth. In nature, apparently, bigger is not always better. In a publication today in the journal Science, scientists outlined the growing...
