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.

Super Yeast Turns Pine into Ethanol

A research team from the University of Georgia has developed a "super strain" of yeast that can efficiently ferment ethanol from pretreated pine - one of the most common species of trees in the U.S. Their research could help biofuels replace gasoline as a transportation fuel.

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.

A Step Forward for Bioremediation

Berkeley Lab researchers have revealed critical genetic secrets of a bacterium that holds potential for removing toxic and radioactive waste from the environment. The researchers have provided the first ever map of the genes that determine how these bacteria interact with their surrounding environment.

Photosynthesis Helper Protein Discovered

Photosynthesis is less efficient in plants than it could be. Red algae, in contrast, use a slightly different mechanism and are thus more productive. Scientists from Germany's Max Planck Institute of Biochemistry (MPIB) have now identified a helper protein for photosynthesis in red algae.

Sustainable Technologies Category Winner

TO:CMA Spherical Generator Angel Francisco Martinez, Delia Beatriz Martinez, and Trupti Bulbule, Cornell University, Ithaca, NYThe TO:CMA Spherical Generator creates copious amounts of clean electricity out of ocean waves at costs below all major existing renewable energy sources. The design is based on the geometrical rearrangement of the Linear Inductance Permanent Magnet Generator (LIPMG). Three rings of concentric sizes and perpendicular arrangement are housed in a waterproof buoy that will transfer the force of the passing waves into motion of magnets. Electrical current is produced as a result of the motion between the wire loop and the magnets in accordance with Faraday’s Law. For synergy reasons, arrays of these buoys will be installed in between wind turbines of offshore wind farms.
