Where the microbe Prochlorococcus lives is not determined primarily by temperature, as previously thought. A study finds a relationship with a shared predator actually sets the microbe's range.

Prochlorococcus are the smallest and most abundant photosynthesizing organisms on the planet. A single Prochlorococcus cell is dwarfed by a human red blood cell, ...

In laboratory experiments, researchers exposed two strains of prochlorococcus to chemicals leached from two common plastic products – grey plastic grocery bags and PVC matting.

Measuring between 0.5 and 0.7 micro­meters, Prochlorococcus is the smallest known ­oxygen-­producing photosynthetic organism.With tens of thousands in every drop of much of the world’s ...

Prochlorococcus is a kind of cyanobacteria (taking their name from their blue color) that floats in oceans the world over. We’re talking a lot of single-celled organisms, with an estimated ...

Prochlorococcus is the smallest oxygenic phototroph in the ocean, where it can be found in great abundance throughout the euphotic zone in mid-latitude waters. Populations of this picocyanobacterium ...

Research on Prochlorococcus, the most abundant life form in the oceans, shows the bacterium's metabolism evolved in a way that may have helped trigger the rise of other organisms, to form a more ...

Prochlorococcus is a type of a cyanobacterium, a microbe that meets its energy needs through photosynthesis. It is estimated to be responsible for 5% of all photosynthesis occurring around the world, ...

And that tea could erode the very foundation of marine ecosystems: the octillion or so (that's 1 with 27 zeros) Prochlorococcus bacteria that produce an estimated 10 percent of our oxygen.
