GLBRC's Technologies

Technologies

As a U.S. Department of Energy (DOE) Bioenergy Research Center, we are positioned to make key discoveries and major advances that will lead to breakthrough technologies for eventual large-scale conversion of biomass into fuels. Each new invention, patent and license listed here represents another step toward that goal.

GLBRC is seeking commercial partners interested in developing the following technologies.

Fatty Acid-Producing Microbes for Generating Medium- and Long-Chain Hydrocarbons

Brian Pfleger, Rebecca Lennen

More Info

New, renewable sources of transportation fuel are needed to meet continuing demand. While the main focus has been on biomass-derived gasoline alternatives such as ethanol and other short-chain alcohols, distillates with higher energy density such as diesel and jet fuel are required for the heavy transportation sector.

Biodiesel is a...

High Starch in Plant Leaves at Senescence

Thomas Sharkey, Sean Weise

More Info

Currently, there is a great interest in using plant biomass, instead of grain, to produce ethanol. Starch can easily be used to make ethanol and would improve ethanol production from cellulose. In most plants, though, starch accumulated during the day is usually broken down each night, resulting in very little...

Economical Growth Media for Production of Cellulolytic Enzymes at High Concentrations

Ming Woei Lau, Bruce Dale, Venkatesh Balan, Shishir Chundawat

More Info

Producing biofuels from cellulosic materials, such as corn stalks, wood chips, and other biomass, requires the use of enzymes to degrade the cellulosic biomass into its molecular components. The cost to produce these enzymes is high, a factor contributing to the limited production of cellulosic ethanol.

Ethanol Tolerant Yeast for Improved Production of Ethanol from Biomass

Audrey Gasch, Jeffrey Lewis

More Info

Ethanol production from cellulosic biomass can make a significant contribution toward decreasing our dependence on fossil fuels. However, the fermentation of biomass can be problematic. One bottleneck in this process is the toxicity of ethanol to microbes such as the yeast Saccharomyces cerevisiae.

A Source and Production Method for Acetyl-Triacylglycerols (ac-TAGs)

Michael Pollard, John Ohlrogge, Timothy Durrett

More Info

Biodiesel can substitute for conventional petroleum diesel in almost all applications. Oftentimes, use of biodiesel requires engine modification since biodiesel has different solvent properties and often degrades natural rubber. Since use of biodiesel is increasing rapidly, alternative biofuel supplies are needed to accommodate the growing demand.

Bacteria Modified to Secrete Biologically Active Protein for Large-Scale Production

Sydnor Withers III, Miguel Dominguez, Matthew DeLisa, Charles Haitjema

More Info

E. coli is the most common prokaryote used to produce protein. The expressed protein generally accumulates in the cytoplasm. While this approach is useful for some proteins, not all proteins can be accumulated in the cytoplasm in an active state. When the desired protein is produced at high levels, it...

High-Yielding Method for Converting Biomass to Fermentable Sugars for Biofuel Production

Ronald Raines, Joseph Binder

More Info

Lignocellulosic biomass is a very desirable feedstock for biofuel production. If the fermentation process for lignocellulose could be optimized, conversion of this biomass could yield 25 to 50 billion gallons of ethanol per year.

However, lignocellulose, which is composed of lignin, cellulose and hemicellulose, is resistant to chemical or enzymatic...

Cell-Free System for Combinatorial Discovery of Enzymes Capable of Transforming Biomass for Biofuels

Brian Fox, Nathaniel Elsen

More Info

Biofuels produced from biomass provide a promising alternative to fossil fuels. Biomass is an inexpensive, readily available and renewable resource. However, the process of converting biomass into biofuels is difficult and costly. Biomass consists of insoluble polysaccharides such as cellulose that are difficult to break down into fermentable sugars like...
