Bacteria Engineered to Eat Switchgrass and Make Transportation Fuels

Researchers with DOE’s Joint BioEnergy Institute (JBEI) have engineered the first strains of Escherichia coli bacteria that can digest switchgrass biomass and synthesize its sugars into all three of those transportation fuels. The microbes are even able to do this without any help from enzyme additives.

Jet Fuel of the Future

With the DOE, Virent, Inc., and the National Renewable Energy Laboratory (NREL) working together, planes may soon take to the skies using less petroleum. In June, DOE announced an award of up to $13.4 million dollars to Virent and its partners to develop a process to cost effectively convert cellulosic biomass - in this case the non-edible parts of corn - into jet fuel.
