[Sndbox] Bacterial Battery In The Works

[Charles]

Bacterial Battery In The Works A University of Massachusetts scientist has discovered a micro-organism that may one day use sugar as a source of low power. "It's a sort of bacterial battery," says Derek R. Lovley, an environmental microbiologist who led the research published in Nature Biotechnology. Lovley took the micro-organism found in Oyster Bay, Va., housed it in a two-compartment fuel cell and fed it sugar. As the micro-organism metabolized the sugar, the freed electrons produced a current, the New York Times reports. "It can transfer more than 80 percent of the electrons available in the sugar, contrary to other microbial fuel cells that use sugar and deliver in the range of 10 percent," Lovley tells the Times.   Charles Mims http://www.the-sandbox.org
