Engineered Stomach Microbe Converts Seaweed Into Ethanol

PolygamousRanchKid writes "Seaweed may well be an ideal plant to turn into biofuel. It grows in much of the two thirds of the planet that is underwater, so it wouldn't crowd out food crops the way corn for ethanol does. Because it draws its own nutrients and water from the sea, it requires no fertilizer or irrigation. Most importantly for would-be biofuel-makers, it contains no lignin—a strong strand of complex sugars that stiffens plant stalks and poses a big obstacle to turning land-based plants such as switchgrass into biofuel. Researchers at Bio Architecture Lab, Inc., (BAL) and the University of Washington in Seattle have now taken the first step to exploit the natural advantages of seaweed. They have built a microbe capable of digesting it and converting it into ethanol or other chemicals. Synthetic biologist Yasuo Yoshikuni, a co-founder of BAL, and his colleagues took Escherichia coli, a gut bacterium most famous as a food contaminant, and made some genetic modifications that give it the ability to turn the sugars in an edible kelp called kombu into fuel."

Re:i doubt that seaweed

You can't compare the edible seaweed in the market with seaweed for ethanol production. It's probably a completely different plant.

Probably? So you don't actually know anything relevant, but you decided to gift and delight us with your comment anyway? Too bad you didn't read the fine summary: "Synthetic biologist Yasuo Yoshikuni, a co-founder of BAL, and his colleagues took Escherichia coli, a gut bacterium most famous as a food contaminant, and made some genetic modifications that give it the ability to turn the sugars in an edible kelp called kombu into fuel." HTH, next time think for more than a tenth of a second before clicking submit.
