Building the framework for the future of biofuels

September 25, 2014 9:47 am | by Joe Kullman, Arizona State Univ. | News | Comments

For more than five years, Amy Landis, an engineering professor at Arizona State Univ.,  has led research that is revealing the potential rewards of developing large-scale biofuels production, as well as the potential drawbacks we would face in the effort. According to Landis, lands damaged by industrial waste or other pollutants could be restored sufficiently to support agriculture for growing bioenergy crops.

Search for better biofuels microbes leads to the human gut

September 25, 2014 8:14 am | by Diana Yates, Life Sciences Editor Univ. of Illinois, Urbana-Champaign | News | Comments

Scientists have scoured cow rumens and termite guts for microbes that can efficiently break down plant cell walls for the production of next-generation biofuels, but some of the best microbial candidates actually may reside in the human lower intestine, researchers report. Their studyis the first to use biochemical approaches to confirm the hypothesis that microbes in the human gut can digest fiber.

Termites evolved complex bioreactors 30 million years ago

September 23, 2014 9:36 am | News | Comments

Achieving complete breakdown of plant biomass for energy conversion in industrialized bioreactors remains a complex challenge, but new research shows that termite fungus farmers solved this problem more than 30 million years ago. The new insight reveals that the great success of termite farmers as plant decomposers is due to division of labor.

August 26, 2014 7:44 am | by National Renewable Energy Laboratory | News | Comments

There’s an old saying in the biofuels industry: “You can make anything from lignin except money.” But now, a new study may pave the way to challenging that adage. The study from the National Renewable Energy Laboratory demonstrates a concept that provides opportunities for the successful conversion of lignin into a variety of renewable fuels, chemicals, and materials for a sustainable energy economy.

Water leads to chemical that gunks up biofuels production

August 21, 2014 7:53 am | by Mary Beckman, Pacific Northwest National Laboratory | Videos | Comments

Trying to understand the chemistry that turns plant material into the same energy-rich gasoline and diesel we put in our vehicles, researchers have discovered that water in the conversion process helps form an impurity which, in turn, slows down key chemical reactions. The study, which was reported online at the Journal of the American Chemical Society, can help improve processes that produce biofuels from plants.

Bionic liquids from lignin

August 19, 2014 7:44 am | by Lynn Yarris, Lawrence Berkeley National Laboratory | News | Comments

While the powerful solvents known as ionic liquids show great promise for liberating fermentable sugars from lignocellulose and improving the economics of advanced biofuels, an even more promising candidate is on the horizon—bionic liquids. Researchers at the Joint BioEnergy Institute have developed “bionic liquids” from lignin and hemicellulose, two by-products of biofuel production from biorefineries.

May 21, 2014 1:58 pm | News | Comments

A new fuel-cell concept from Michigan State Univ. allows biodiesel plants to eliminate the creation of hazardous wastes while removing their dependence on fossil fuel from their production process. The platform, which uses microbes to glean ethanol from glycerol and has the added benefit of cleaning up the wastewater, should give producers the opportunity to reincorporate the ethanol and the water into the fuel-making process.

Roadmap shows how to improve lignocellulosic biofuel biorefining

May 16, 2014 8:00 am | by Brett Israel, Georgia Institute of Technology | News | Comments

When making cellulosic ethanol from plants, one problem is what to do with a woody agricultural waste product called lignin. The old adage in the pulp industry has been that one can make anything from lignin except money. A new review article in Science points the way toward a future where lignin is transformed from a waste product into valuable materials such as low-cost carbon fiber for cars or bio-based plastics.
