A team of Virginia Tech researchers, led by Dr. Y.H. Percival Zhang, has developed a process to convert xylose—the second-most abundant sugar in plants—into hydrogen with approaching 100% of the theoretical yield. The findings of their study, published in the journal Angewandte Chemie, International Edition, suggest that cell-free biosystems could produce hydrogen from biomass xylose at low cost.
In the process, hydrogen is produced from xylose and water in one reactor containing 13 enzymes, including a novel polyphosphate xylulokinase (XK). The method can be performed using any source of biomass.
Obama Administration releases National Bioeconomy Blueprint; health, food, energy and environment
April 26, 2012
The White House today released a national Bioeconomy Blueprint, a comprehensive approach to harnessing innovations in biological research to address national challenges in health, food, energy, and the environment. In coordination with the Blueprint’s release, Federal officials also announced a number of new commitments to help achieve the Blueprint’s goals.
The National Bioeconomy Blueprint describes five strategic objectives for a bioeconomy with the potential to generate economic growth and address societal needs. Although progress is being made in all of these areas, according to the Blueprint, much work remains if the United States is to remain competitive. The objectives are:
