Highlighted technologies:A Method of Modifying Lignin to Improve Biomass Utilization Lignin is a complex, heterogeneous polymer found in all vascular plants. It rigidifies plants and plays a crucial role in water transport. However, lignins are effectively indigestible and interfere… John Ralph, John Grabber | P100199US02 Extending Juvenile Stage of Plants for Biofuels and Feedstock Juvenile and adult grass tissue dramatically differs in anatomy, chemistry and ability to withstand stresses. Juvenile plants cannot flower and their leaves are better able to resist cold and drought…. Shawn Kaeppler, Natalia de Leon Gatti, Jillian Foerster | P120179US02 Grass Modified for Easier Bioprocessing Manufacturing paper and producing biofuels is difficult because the lignin in plant cell walls is tough to degrade. Current techniques are energy intensive and use harsh chemicals. In the case of biof… John Ralph, Curtis Wilkerson, Saunia Withers, John Sedbrook | P120040US02 Inbred Corn Lines for Developing Silage Hybrids Corn silage is a high quality forage crop used on many dairy and cattle farms. The goal of making silage is to preserve the harvested crop by anaerobic fermentation, where bacteria convert soluble car… Natalia de Leon Gatti, James Coors, Dustin Eilert, Patrick Flannery | P090407US01
Powerful New Enzyme for Transforming Biomass Converting plant cellulose and hemicellulose into fermentable sugars is a major bottleneck in the biofuel industry. Chemical pretreatment and enzyme hydrolysis (breakdown) usually are required. Amon… Brian Fox, Christopher Bianchetti, Taichi Takasuka | P120371US02 Unleashing Biomass Sugars Using Bromine Salt Methods to produce bioethanol from cornstarch or sugarcane are inadequate to meet the global demand for renewable fuels. To be sustainable, biofuel production should rely on abundant, cheap, inedible … Xuejun Pan, Li Shuai | P110209US02 Concentrated C5 and C6 Sugars from Biomass Widespread production of sustainable fuels and chemicals will require cost-effective methods for breaking down biomass into its constituent sugars. Attaining high yields of concentrated C5 and C6 carb… James Dumesic, David Martin Alonso, Jeremy Luterbacher | P140075US01 Enzymatic Depolymerization of Lignin Lignin is a renewable resource that accounts for up to 30 percent of the dry weight of vascular plant cell walls. It is comprised of aromatic compounds that may be valuable commodities for the biofuel… Timothy Donohue, Daniel Gall, Wayne Kontur, Hoon Kim, John Ralph, Daniel Noguera, Brian Fox, Craig Bingman | P170274US02 Flow-Based Aerobic Depolymerization of Lignin UW-Madison researchers have developed a flow reactor for lignin valorization. The flow-based reactor increases monomer production while limiting unwanted side/subsequent reactions. In particular, mate… Shannon Stahl, Christopher Holland, Eric Weeda, Thatcher Root | P220013WO01
Solar Cells for Reducing HMF to Valuable Platform Chemicals A biomass-derived chemical called HMF (5-hydroxymethylfurfural) can be turned into a variety of industrial molecules. For example, it can be reduced to BHMF or 2,5-bis(hydroxymethyl) furan, an importa… Kyoung-Shin Choi, John Roylance, Stephen Kubota | P150141US01 Synthesis of Bio-Based Polyurethanes and Polyesters Plant biomass remains a promising renewable source of important platform chemicals currently derived from petroleum. These include the chemical building blocks used to make polyurethanes (commonly fou… George Huber, Hochan Chang, James Dumesic | P210122US01 Method to Produce Furandicarboxylic Acid (Fdca) from 5-Hydroxymethylfurfural (Hmf) The platform molecule HMF is derived from biomass and converted into a variety of downstream products. One of the most important of these is FDCA, which is used as a monomer in the production of fiber… James Dumesic, Ali Hussain Motagamwala | P160074US01 One-Step Process to Generate Lignin-Derived Aromatics from Raw Biomass Lignocellulosic biomass is a renewable energy source with great potential for generating value-added chemicals. One of the major components of biomass is lignin (15-25 percent). Due to its infamo… Shannon Stahl, Hao Luo | P190134US02 Improved Method for Converting Biomass into Levulinic Acid for Renewable Fuel Sources Increasing crude oil prices and concerns with sustainability have led to a growing interest in producing chemicals and fuels from renewable sources. A major focus for the replacement of petroleum feed… Troy Runge | P110356US01 Levulinic acid is a biomass-derived compound that can be obtained inexpensively in high yields from waste cellulose-containing materials. It has been identified as a top biomass-derived chemical due t… James Dumesic, David Martin Alonso, Jesse Bond, Dong Wang, Ryan West | P100099US01
Fatty Acid-Producing Microbes for Generating Medium- and Long-Chain Hydrocarbons 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 alcohol… Brian Pfleger, Rebecca Lennen | P09329US02 Recombinant High-Lipid Microbe for Bioproduct & Biofuel Production Lipids derived from microorganisms, including bacteria, yeast and microalgae, offer a promising source of renewable fuels and chemicals. Oleaginous microbes – defined as those accumulating more than… Timothy Donohue, Kimberly Lemmer, Weiping Zhang, Daniel Noguera | P170068US02 Microorganisms and Methods for Producing 2-Pyrone-4,6-Dicarboxylic Acid and Other Compounds Recombinant microorganisms configured for enhanced production of compounds such as 2-pyrone-4,6-dicarboxylic acid (PDC) and methods of using the recombinant microorganisms for the production of these … Timothy Donohue, Jose Perez, Wayne Kontur, Daniel Noguera, German Umana Chapeton | P180219US02 Modified Yeast to Boost Biofuel Yields Producing biofuel on an industrial scale requires efficient fermentation of cellulosic plant material.
