Ethanol from brown seaweed

“Bioengineers have devised a way to produce ethanol from seaweed, laying the groundwork for a biofuel that doesn’t sacrifice food crops.

Yasuo Yoshikuni and his colleagues at the Bio Architecture Lab in Berkeley, California, engineered the bacterium Escherichia coli so that it could digest brown seaweed and produce ethanol. Their work is published in Science today1.

Yoshikuni says that his group chose brown seaweed because it was both sustainable and scalable. “Seaweed is already produced in huge quantities around the world without taking up any fresh water or arable land.” Brown seaweed also grows faster than red or green seaweed, with varieties such as the giant kelp, found off the coast of California, growing by up to a metre a day.”
