Definitions
from The American Heritage® Dictionary of the English Language, 5th Edition.
- noun Any of various photosynthetic bacteria of the phylum Cyanobacteria that are generally blue-green in color and are widespread in marine and freshwater environments, with some species capable of nitrogen fixation.
from the GNU version of the Collaborative International Dictionary of English.
- 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.

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.

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.
