Bactéria contribui para a produção de biodiesel

(Notícia em inglês)
Gene scientists have coaxed bacteria into eating agricultural waste and secreting diesel, offering a potentially cheaper, greener energy source than present-day biofuels, a study said.

Soaring demand for the current mainstay source for biodiesels - corn, sugar and other starchy crops - has caused the prices of some staple foods to soar as farmland is turned over to fuel crops, and worsened deforestation.

Some researchers also doubt whether there is a significant net reduction in emissions of greenhouse gases, given the inputs needed from fossil fuels, in ploughing, fertilising, harvesting and processing and so on, to make biofuel.
