Scientists hunting for ways to drive down the cost of converting plant waste into fuel may have found some valuable clues in the bellies of cows.
Researchers employing high-tech genetic sequencing methods identified dozens of gut-dwelling organisms that help cows break through the protective sheath that guards the sugars inside plants. Some of these enzymes may eventually help biofuel companies scale up their efforts to turn plant waste into fuel, say researchers from the U.S. Department of Energy’s Joint Genome Institute.
