     BEIJING, May 24 (Xinhuanet) -- Scientists revealed for the first time the molecular1 structure of proteins, which enables bacteria to transfer electrical charges, according to a new study.

    The revelation was published in Proceedings2 of the National Academy of Sciences in the U.S. on Monday.
    Scientists used a technique called "x-ray crystallography" to reveal the molecular structure of proteins, which work as atom-sized "wires" discharging excess electricity.
    "This is an exciting advance in our understanding of how some bacterial3 species move electrons from the inside to the outside of a cell," said lead author Tom Clarke of the University of East Anglia's School of Biological Sciences in Norwich, England.
    He said this discovery means "We can now start developing efficient 'bio-batteries' as the viable4 energy source in the future."Still, it could take perhaps a decade to go. Before that, existing uses of such bacteria needed to become 100 or 1,000 times more efficient, he said.
    The advance could also hasten the development of microbe technology that can help clean up oil or uranium pollution, he said.
    Microbes might in future be enlisted5 to clean up nuclear accidents such as Japan's Fukushima Daiichi disaster, he added.(本文由在线英语听力室整理编辑)
