Researchers Develop Method for Enzymatic Production of Hydrogen from Biomass at High Yields
23 May 2007

The synthetic metabolic pathway for conversion of polysaccharides and water to hydrogen and carbon dioxide. Researchers at Virginia Tech, Oak Ridge National Laboratory (ORNL), and the University of Georgia have developed a novel method using multiple enzymes as a catalyst for the direct, low-cost production of hydrogen from biomass.

Applying the principles of synthetic biology, the researchers use a combination of 13 enzymes to form an unnatural enzymatic pathway to completely convert polysaccharides—e.g., starch and cellulose—and water into hydrogen at a yield higher than the theoretical yield of biological hydrogen fermentations.
