Boosting Bioenergy
— A team led by Oak Ridge National Laboratory’s Jeremy Smith, the director of ORNL’s Center for Molecular Biophysics and a Governor’s Chair at the University of Tennessee, has uncovered information that could help others harvest energy from plant mass. The team’s conclusion—that less ordered cellulose fibers bind less lignin—was published in the August edition of Biomacromolecules.

ORNL BioEnergy Science Center funding renewed
— The U.S. Department of Energy today announced it would fund its three Bioenergy Research Centers for an additional five-year period, subject to continued congressional appropriations.

Human mouth microbes provides insight into health, disease
— Microbes from the human mouth are telling Oak Ridge National Laboratory scientists something about periodontitis and more after they cracked the genetic code of bacteria linked to the condition.

ORNL scientists solve mercury mystery
— By identifying two genes required for transforming inorganic into organic mercury, which is far more toxic, scientists today have taken a significant step toward protecting human health.

'Zoomable' map of poplar proteins offers new view of bioenergy crop
— Researchers seeking to improve production of ethanol from woody crops have a new resource in the form of an extensive molecular map of poplar tree proteins, published by a team from the Department of Energy's Oak Ridge National Laboratory (DOE ORNL).

ORNL researchers improve soil carbon cycling models
— A more robust model of the soil carbon cycle developed at Oak Ridge National Laboratory (ORNL) improves understanding of carbon residence time in soils and enables scientists to make more accurate climate predictions.

DOE grant to support enhanced biofuel crop design
— DOE has awarded a $14.3 million grant to study crassu­lacean acid metabolism (CAM) and drought tolerance in biofuel crops to a research team that includes Oak Ridge National Laboratory and the University of Tennessee.

BESC submits 32 gene disclosures for future patents
— The Bioenergy Science Center (BESC) at Oak Ridge National Laboratory (ORNL) is preparing invention disclosures for 32 different genes that can help improve the yield of ethanol from cellulosic biomass. These genes or their variants function to overcome recalcitrance—difficulty in breaking down cellulosic biomass to release sugars.

Final report on intermediate ethanol blends research published
— ORNL published a final report on the Intermediate Blends Catalyst Durability Study in February 2012. The two-year program, led by researchers from the Fuels, Engines, and Emissions Research Center, involved driving 82 vehicles over 6 million miles with periodic emissions tests to evaluate the effects of ethanol blends (E10, E15, and E20) on emissions control system durability.

Tension wood holds clues to higher fuel yields from biomass crops
— The properties that enable trees to flex in the wind might also prove use­ful in designing better biomass crops. Researchers at the BioEnergy Science Center (BESC) at Oak Ridge National Laboratory (ORNL) are studying those prop­erties to understand how they affect the release of plant sugars that become biofuels.

'Low tech' light in neutron beam illuminates photosynthesis in bacteria
— Researchers have measured the phase behavior of green house gases in pores at the angstrom level, using small-angle neutron scattering (SANS) at the Oak Ridge National Laboratory’s High Flux Isotope Reactor.
