UCLA researchers use bacteria to convert carbon dioxide to isobutanol fuel using solar photosynthesis. Isobutanol can be used as tranportation fuel using the existing gasoline infrastructure. …
… “In a new approach, 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 holds great potential as a gasoline alternative. ” …
