Team uses cellulosic biofuels byproduct to increase ethanol yield

Scientists report in Nature Communications that they have engineered yeast to consume acetic acid, a previously unwanted byproduct of the process of converting plant leaves, stems and other tissues into biofuels. The innovation ...

Fermenting fodder into fuel

(PhysOrg.com) -- As climate change challenges continue to crop up around fossil fuel use and greenhouse gas emissions such as carbon dioxide, identifying renewable fuel materials and developing processes that produce environmentally ...

Unlocking lignin for sustainable biofuel

Turning trees, grass, and other biomass into fuel for automobiles and airplanes is a costly and complex process. Biofuel researchers are working to change that, envisioning a future where cellulosic ethanol, an alcohol derived ...

Next generation of biofuels is still years away

The first trickle of fuels made from agricultural waste is finally winding its way into the nation's energy supply, after years of broken promises and hype promoting a next-generation fuel source cleaner than oil.

Engineered yeast could expand biofuels' reach

Boosting production of biofuels such as ethanol could be an important step toward reducing global consumption of fossil fuels. However, ethanol production is limited in large part by its reliance on corn, which isn't grown ...
