      <title>New Concept to Obtain Higher Yields of Pyrolytic Sugars for Ethanol Production</title>
      <link>https://rip.trb.org/View/1367953</link>
      <description><![CDATA[The objectives of this research project are as follows: (1) Identification of the best pretreatment and pyrolysis conditions to maximize the yield of anhydro-sugars; (2) A mathematical model that will be helpful in the design and scale up of more selective mobile pyrolysis units to produce bio-oils enriched in anhydro-sugars; (3) Identification of the best conditions to separate, hydrolyze, detoxify and ferment the pyrolytic sugars to produce ethanol; and (4) Economic analysis of the proposed concept.]]></description>

      <title>Synergies between Heme Peroxidases and Cellulases in the Bioconversion of Lignocellulosic Feedstocks to Ethanol</title>
      <link>https://rip.trb.org/View/1367711</link>
      <description><![CDATA[An enzymatic process for the bioconversion of softwood to sugars for fermentation to ethanol will be developed, including optimization of the cellulase formulation specifically for hydrolysis of Douglas-fir pretreated by acid-catalyzed steam explosion. High throughput methods to intensively optimize enzyme composition for the specific softwood feedstocks available in the Western region may provide sound data with which realistic economic analysis may be performed and policy issues regarding the near-term expectations for lignocellulosic ethanol enlightened. 
Microorganisms produce a “barrage” of extracellular enzymes when growing on wood, and these “auxiliary” enzymes are likely to increase the rate of cellulose hydrolysis in complex lignocellulosic substrates. Using a high throughput approach, synergies between cellulases and heme peroxidases can be explored. It is likely from the scientific evidence available that heme peroxidases will increase cellulase activity by removing residual lignin. The proposed research using heme peroxidases will provide quantitative measurements as to the significance of this effect, and may provide evidence of other previously undiscovered auxiliary enzymes or synergistic interactions. Further exploiting the true metabolic potential of wood-degrading fungi may lower the cost of producing lignocellulosic ethanol from softwoods, providing a significant source of transportation fuel from the prevalent forestry wastes in the Western region.]]></description>

      <title>Influence of Alternative Pretreatment Strategies on Cellulosic Ethanol Production Using Simultaneous Saccharification and Fermentation of High Solids</title>
      <link>https://rip.trb.org/View/1364477</link>
      <description><![CDATA[The objective of this research project is to improve efficiency of ethanol production from Switchgrass through basic research into the inhibitory by-products that build up during conversion process.  The experimental approach - which is  about to commence -- includes two parallel studies with switchgrass and  mixed prairie biomass (MPB). The first study will consist of a series of cellulase binding experiments with swichgrass and MPB, and the second study will use Fourier Transform Infrared (FTIR) spectroscopy to analyze the same biomass substrates.]]></description>
