Bacteria Turns Carbon Dioxide Into Liquid Fuel

Researchers from the UCLA Henry Samueli School of Engineering and Applied Science have genetically modified a cyanobacterium to consume carbon dioxide and produce the liquid fuel isobutanol, which has great potential as a gasoline alternative. The reaction is powered directly by energy from sunlight, through photosynthesis.
