UGA discovery may allow scientists to make fuel from CO2 in the atmosphere

riosus, or "rushing fireball," which thrives by feeding on carbohydrates in the super-heated ocean waters near geothermal vents. By manipulating the organism's genetic material, Adams and his colleagues created a kind of P. furiosus that is capable of feeding at much lower temperatures on carbon dioxide.

The research team then used hydrogen gas to create a chemical reaction in the microorganism that incorporates carbon dioxide into 3-hydroxypropionic acid, a common industrial chemical used to make acrylics and many other products.

With other genetic manipulations of this new strain of P. furiosus, Adams and his colleagues could create a version that generates a host of other useful industrial products, including fuel, from carbon dioxide.

When the fuel created through the P. furiosus process is burned, it releases the same amount of carbon dioxide used to create it, effectively making it carbon neutral, and a much cleaner alternative to gasoline, coal and oil.

"This is an important first step that has great promise as an efficient and cost-effective method of producing fuels," Adams said. "In the future we will refine the process and begin testing it on larger scales."
