*Joint BioEnergy Institute (JBEI) Researchers Reach Milestone on the Road to Biofuels*
A milestone has been reached on the road to developing advanced biofuels that can replace gasoline, diesel and jet fuels with a domestically-produced clean, green, renewable alternative.
Researchers with the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI) have engineered the first strains of Escherichia colibacteria that can digest switchgrass biomass and synthesize its sugars into all three of those transportation fuels. What’s more, the microbes are able to do this without any help from enzyme additives. (more…)
The U.S. Department of Energy’s (DOE) recent decisions about how to fund fuel cell research, he says, are putting the country at risk of falling behind in the development and implementation of the most efficient means of converting fuel to electricity. Fuel cells have up to three times the efficiency of an internal combustion engine. (more…)
Right now, it looks a little like one of those plastic containers you might fill with gasoline when your car has run dry. But Scott Gallager is not headed to the nearest Mobil station. The Woods Hole Oceanographic Institution (WHOI) biologist has other, grander plans for his revolutionary Swimming Behavioral Spectrophotometer (SBS), which employs one-celled protozoa to detect toxins in water sources.
Not only is he working on streamlining the boxy-looking contraption—eventually even evolving it into a computer chip—but he sees it as a tool to potentially “monitor all the drinking water in the world.

Researchers at the U.S. Department of Energy’s Joint BioEnergy Institute (JBEI) have created a technoeconomic model that should help accelerate the development of a next generation of clean, green biofuels that can compete with gasoline in economics and well as performance. This on-line, wiki-based model enables researchers to pursue the most promising strategies for cost-efficient biorefinery operations by simulating such critical factors as production costs and energy balances under different processing scenarios.
“The high production cost of biofuels has been the main factor limiting their widespread adoption,” says JBEI’s Daniel Klein-Marcuschamer. “We felt that a model of the biorefinery operation that was open, transparent about the assumptions it uses, and updatable by the community of users could aid in guiding research in the direction where it is most likely to reduce the production cost of biofuels.” (more…)
