UCR Novel Pretreatment Technology

Researchers at the University of California, Riverside have invented a novel pretreatment technology that could cut the cost of biofuels production by about 30 percent or more by dramatically reducing the amount of enzymes needed to breakdown the raw materials that form biofuels.

As partners in the BioEnergy Science Center (BESC), the team from theBourns College of Engineering Department of Chemical and Environmental Engineering and Center for Environmental Research and Technology (CE-CERT) have shown that this new operation called Co-solvent Enhanced Lignocellulosic Fractionation (CELF) could eliminate about 90 percent of the enzymes needed for biological conversion of lignocellulosic biomass to fuels compared to prior practice. This development could mean reducing enzyme costs from about $1 per gallon of ethanol to about 10 cents or less.

Second annual Bioenergy Day @ UGA to welcome seventh graders

Athens, Ga. - More than 400 Athens seventh-graders will experience firsthand how wood and other plant biomass generate energy at the second annual Bioenergy Day @ UGA on Nov. 12 from 9:30 a.m. to 1:30 p.m. at the State Botanical Garden.

UGA faculty and students will be on hand to guide students from Hilsman and Coile middle schools through the hands-on displays about producing renewable energy from biological sources.

Interactive exhibits were developed by staff from the BioEnergy Science Center, or BESC, and the Creative Discovery Museum in Chattanooga, Tennessee, and departments from across UGA.

Signatures of selection inscribed on poplar genomes

A recent study published online August 24, 2014 in Nature Genetics offers a more in-depth, population-based approach to identifying such mechanisms for adaptation, and describes a method that could be harnessed for developing more accurate predictive climate change models. For the U.S. Department of Energy, which is developing biomass crops for biofuels production, this knowledge could determine which genotypes – genetic makeup of an organism – of biomass crop may thrive better than others in certain environments. The team led by Gerald Tuskan of Oak Ridge National Laboratory (ORNL), the Department of Energy Joint Genome Institute (DOE JGI) and Stephen DiFazio of West Virginia University, used a combination of genome-wide selection scans and analyses to understand the processes involved in shaping the genetic variation of natural poplar (Populus trichocarpa) populations.

A team of researchers, led by Professor Charles E. Wyman, at the University of California, Riverside’s Bourns College of Engineering have developed a versatile, relatively non-toxic, and efficient way to convert raw agricultural and forestry residues and other plant matter, known as lignocellulosic biomass, into biofuels and chemicals.

Improving commercial viability of biofuels

Charles Wyman, A University of California, Riverside Bourns College of Engineering professor is one of the authors of a paper recently published in Science that outlines ways companies can commercialize and profit from what was thought to a waste product created when producing biofuels.
