Engineering of Bacteria for Production of Methyl Ketone Biofuels from CO2

Source:  Harry Beller

Harry_image_for_webRalstonia eutropha is a chemolithoautotrophic bacterium able to grow with organic substrates or H2 and CO2 under aerobic conditions.  Its ability to utilize CO2 as a sole carbon source renders it an interesting new candidate host for the production of renewable liquid transportation fuels. A team of LBNL scientists, including ESD's Harry Beller and Steve Singer, engineered R. eutropha for the production of fatty acid-derived, diesel-range methyl ketones from CO2.  This was the first report of autotrophic production of methyl ketones by engineered bacteria.
