Engineered Bacteria Produce Biofuel Alternative For High-Energy Rocket Fuel
2014-03-28 17:55:28

John Toon, Georgia Institute of Technology Researchers at the Georgia Institute of Technology and the Joint BioEnergy Institute have engineered a bacterium to synthesize pinene, a hydrocarbon produced by trees that could potentially replace high-energy fuels, such as JP-10, in missiles and other aerospace applications. With improvements in process efficiency, the biofuel could supplement limited supplies of petroleum-based JP-10, and might also facilitate development of a new generation...

Scientists Discover Bacterial Resistance To Improve Biofuel Production
2014-03-28 14:49:50

Lynn Yarris, Berkeley Lab Researchers with the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI), a multi-institutional partnership led by Berkeley Lab, have identified the genetic origins of a microbial resistance to ionic liquids and successfully introduced this resistance into a strain of E. coli bacteria for the production of advanced biofuels. The ionic liquid resistance is based on a pair of genes discovered in a bacterium native to a tropical rainforest in Puerto...

Lignin-Feasting Microbe Could Be Used For Biofuels
2013-11-13 16:08:10

Lawrence Berkeley National Laboratory Nature designed lignin, the tough woody polymer in the walls of plant cells, to bind and protect the cellulose sugars that plants use for energy. For this reason, lignin is a major challenge for those who would extract those same plant sugars and use them to make advanced biofuels. As part of their search for economic ways to overcome the lignin challenge, researchers at the Joint BioEnergy Institute (JBEI) have characterized the enzymatic activity of...

The first dynamic regulatory system that prevents the build-up of toxic metabolites in engineered microbes has been reported by a team of researchers with the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI). The JBEI researchers used their system to double the production in Escherichia coli (E. coli) of amorphadiene, a precursor to the premier antimalarial drug artemisinin. Using genome-wide transcriptional analysis, the JBEI researchers identified native regions of...

Researchers Develop Enzyme-free Ionic Liquid Pre-treatment For Cellulosic Biomass
2013-05-09 11:43:26

Lawrence Berkeley National Laboratory Advanced biofuels — liquid fuels synthesized from the sugars in cellulosic biomass — offer a clean, green and renewable alternative to gasoline, diesel and jet fuels. Bringing the costs of producing these advanced biofuels down to competitive levels with petrofuels, however, is a major challenge. Researchers at the U.S. Department of Energy (DOE)´s Joint BioEnergy Institute (JBEI), a bioenergy research center led by Berkeley Lab, have...

A Microbe Which Can Handle Ionic Liquids
2012-05-15 05:23:38

New find from Joint BioEnergy Institute could help reduce biofuel production costs In the search for technology by which economically competitive biofuels can be produced from cellulosic biomass, the combination of sugar-fermenting microbes and ionic liquid solvents looks to be a winner save for one major problem: the ionic liquids used to make cellulosic biomass more digestible for microbes can also be toxic to them. A solution to this conundrum, however, may be in the offing....

Joint BioEnergy Institute Researchers Develop Dynamic System for Regulating Metabolic Pathways Significant boosts in the microbial production of clean, green and renewable biodiesel fuel has been achieved with the development of a new technique in synthetic biology by researchers with the U.S. Department of Energy (DOE)´s Joint BioEnergy Institute (JBEI). This new technique — dubbed a dynamic sensor-regulator system (DSRS) — can detect metabolic changes in microbes during...

A  class of chemical compounds used for flavor and fragrance may one day become a clean, renewable resource with which to fuel our automobiles. U.S. Department of Energy researchers have modified the E. Coli bacteria to create large quantities of methyl ketone from glucose. First tests of this methyl ketone show very high cetane numbers. Cetane is a fuel rating system for diesel fuel, similar to octane ratings for gasoline. This makes the methyl ketones a viable candidate for production...

Joint BioEnergy Institute Researchers Identify Key Enzyme Structure The recent discovery that bisabolane, a member of the terpene class of chemical compounds used in fragrances and flavorings, holds high promise as a biosynthetic alternative to D2 diesel fuel has generated keen interest in the green energy community and the trucking industry. Now a second team of researchers with the U.S Department of Energy (DOE)´s Joint BioEnergy Institute (JBEI) has determined the three-dimensional...
