The natural abundance of hydrogen and its capacity to store and
release energy in a nonpolluting manner make it highly appealing as a
potential source of energy. But at present, about 95 percent of U.S.
hydrogen is derived from petroleum or natural gas, via a process called
"steam reforming." So scientists are evaluating bacterial
species--including Bacteroides and Shewanella--for their potential use
in fuel-cell systems. The systems would use mixtures of selected
bacteria to treat organic wastewater, catalyzing release of protons and
electrons, which could then produce electricity or hydrogen fuel.
The resources of the ARS Microbial Culture Collection--comprising about 87,000 microbial strains from around the world--are being tapped for bacterial candidates. The 3-year project is being done in cooperation with researchers at Washington University, St. Louis, Missouri. Michael A.
