Cyanobacteria as an example of astrobiology and biotechnology. Cyanobacteria fulfill two important roles in Earth habitability: the production of oxygen (right) and the fixation of carbon (from atmospheric carbon dioxide, left). Cyanobacteria are credited with significantly increasing global oxygen levels around 2.4 billion years ago, which shifted our planet's redox conditions and could have spurred the evolution of eukaryotes and complex life. In the modern day, their voracious consumption of atmospheric carbon dioxide can be harnessed to again shift planetary-scale processes by sequestering carbon as biomass, carbonate, or biofuel products. -- EarthRx
