Scientists have found a way to grow plants for biofuels on
unproductive, barren or contaminated soil, without appropriating fertile croplands - just add the right kind of bacteria. “If we have bacteria that can help plants to grow better, we can then use these soils for the economic production of biofuels,” said Daniel van der Lelie, microbiologist at Brookhaven National Lab on Long Island, New York. The Brookhaven group found that adding the right kinds of naturally occurring bacteria to the roots of poplar trees increased their biomass production by up to 80 percent over 10 weeks.
