Biofuels from Seaweed

E. coli, best known for causing serious food poisoning, has been bioengineered to digest all the sugars found in seaweed and produce bioethanol and other useful products. The researchers estimate that seaweed farms along 3% of the world’s coastlines could produce 60 billion gallons (about 227 billion litres) of ethanol a year, using this technique. It is unlikely any accidental release of engineered E. coli could damage seaweed growing in the sea, as the microbes are not suited to the ocean environment.
