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 ...

Single-celled ocean microbes known as Pelagibacter or SAR11 make up about 25 percent of the plankton on the planet. They might be the most common bacteria in the world. The vast numbers of ...

An example of a transport protein in a SAR11 bacterium and its distribution in samples of ocean from across the world. Because of their abundance, these transport proteins are widely distributed ...

A group of ocean bacteria long considered perfectly adapted to life in nutrient-poor waters may be more vulnerable to environmental change than scientists realized. The bacteria, known as SAR11, ...

Marine microbes control the flux of matter and energy essential for life in the oceans. Among them, the bacterial group SAR11 accounts for about a third of all the bacteria found in surface ocean ...

Bacterioplankton of the SAR11 clade are the most abundant microorganisms in marine systems, usually representing 25% or more of the total bacterial cells in seawater worldwide. SAR11 is divided into ...

A study led by the University of Hawaiʻi at Mānoa's Hawaiʻi Institute of Marine Biology (HIMB) has revealed critical new details about one of the ocean's most abundant life forms—SAR11 marine bacteria ...

The discovery of new viruses that appear to be spread around the world's oceans hints at a war waging between such viruses and their prey: an abundant group of bacteria. The bacteria, collectively ...

It's estimated that 90 percent of the biomass in the oceans is made up of marine microorganisms, a group that includes protists, bacteria, archaea, fungi, and viruses. Microbes lives in some of the ...
