Bacteria engineered to turn carbon dioxide into liquid fuel

Global climate change has prompted efforts to drastically reduce emissions of carbon dioxide, a greenhouse gas produced by burning fossil fuels. In a new approach, researchers have genetically modified a cyanobacterium to consume carbon dioxide and produce a liquid fuel precursor to isobutanol, which holds great potential as a gasoline alternative. The reaction is powered directly by energy from sunlight, or photosynthesis.
