from The American Heritage® Dictionary of the English Language, 4th Edition
- n. A photosynthetic bacterium of the class Coccogoneae or Hormogoneae, generally blue-green in color and in some species capable of nitrogen fixation. Cyanobacteria were once thought to be algae. Also called blue-green alga.

- n. Any of very many photosynthetic prokaryotic microorganisms, of phylum Cyanobacteria, once known as blue-green algae.

- any of a group of photosynthetic autotrophic prokaryotic microorganisms possessing characteristics of both bacteria and plants. When classed as bacteria, they are assigned to the Cyanobacteria; when classed as plants, they are assigned to the Cyanophyta. They were earlier named blue-green algae, a term less used now in technical discussions. Since the chlorophyll within the cyanobacteria is diffused throughout the cell, rather than being contained in chloroplasts, they are no longer thought of as true plants.
Synechococcus is a genus of cyanobacterium which is distributed widely in the oceans, although there are also some freshwater species.
Here we see a sheath, and on the inside can see a chain of cells, rod-shaped cells, that make up the trichome of a cyanobacterium.
He also puts up an image of a cyanobacterium that appears to house a stack of dimes all just faintly connected.
To make his case, he puts on a slide show: First he shows images of a living cyanobacterium a microbe sometimes called blue-green algae and highlights some characteristics—long filaments made up of cells with small indentations where they meet.
The company worked in "stealth mode" for a couple years before it recently began revealing more about what it was doing, including with a patent last year for its production of diesel molecules from its cyanobacterium.
The flat, solar-panel style "bioreactors" that house the cyanobacterium are modules, meaning they can build arrays at facilities as large or small as land allows, the company says.
A key for Joule is the cyanobacterium it chose, which is found everywhere and is less complex than algae, so it's easier to genetically manipulate, said biologist Dan Robertson, Joule's top scientist.
Joule claims, for instance, that its cyanobacterium can produce 15,000 gallons of diesel full per acre annually, over four times more than the most efficient algal process for making fuel.
The only thing "big red" has to offer future settlers is rust, dust and lots of CO2–the latter which can be converted into fuel thanks to our new best microscopic friend cyanobacterium.
Scientists have been studying this little creature and have found that with a "few" alterations, cyanobacterium can take CO2 the gas that can easily kill you and turn it into a biofuel called isobutanol.
