Yeast makes ethanol to prevent metabolic overload

Why do some yeast cells produce ethanol? Scientists have wondered about this apparent waste of resources for decades. Now, University of Groningen scientists think they have a solution: yeast cells produce ethanol as a 'safety ...

Carbon fuels go green for renewable energy

For decades, scientists have searched for effective ways to remove excess carbon dioxide emissions from the air, and recycle them into products such as renewable fuels. But the process of converting carbon dioxide into useful ...

Improving poplar biomass production under stress conditions

Inside the phytotron, rows of white industrial cabinets hide the life expected in a greenhouse. A peek through a square viewing port, however, reveals the green energy growing inside the bright chamber. These specific poplar ...

PNNL technology clears way for ethanol-derived jet fuel

ASTM International recently revised ASTM D7566 Annex A5—the Standard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons—to add ethanol as an approved feedstock for producing alcohol-to-jet synthetic ...

How biofuels from plant fibers could combat global warming

Scientists, companies and government agencies are hard at work on decreasing greenhouse gas emissions that cause climate change. In recent years, biofuels produced from corn have emerged as a fuel source to power motor vehicles ...
