Churchville, VA—Researchers may have broken the biofuel barrier. A new biotech discovery enables ethanol to be made from a common variety of brown seaweed. This would by-pass the biggest problem with corn ethanol and biodiesel—the world’s shortage of cropland. The new ethanol process uses the familiar E coli bacterium working on kombu, a variety of edible brown kelp, which is common in the world’s seas and oceans. It has been grown and harvested commercially by such countries as China, Japan, and Korea for hundreds of years. If you like sushi, it is the brown wrapping on your favorites.
