7 gautam sarath

  1. 1. USDA-Agricultural Research ServiceResearch Units in Lincoln are closely tied to the University We all perform collaborative researchGrain, Forage and Bioenergy Agroecosystems Research UnitResearch Unit University of Nebraska Agricultural Research Division Sarat Sarath – Transatlantic Conference Lincoln Oct 17
  2. 2. Major Research Objectives Forage & Bioenergy Current project 2008-20131. Improved management practices and tools for grazed grasslands in the Central Plains and Midwest.2. Improved plant materials for grasslands of livestock production systems in the Central Plains and Midwest.3. Improved plant materials, primarily switchgrass, for biomass energy production systems.4. Develop sustainable production systems for switchgrass and other perennial grasses for biomass energy. Sarath – Transatlantic Conference Lincoln Oct 17
  3. 3. ARS Switchgrass Bioenergy Cooperative Research Mandan, ND St. Paul, MN Madison, WI Management Quality Switchgrass Management Other Grasses Corvallis, OR Breeding Gasification Management Other Grasses College Park, PA Albany, CA Switchgrass ManagementSwitchgrassMolecular genetics ERRC, PA Lincoln, NE Gasification Switchgrass Logan, UT Other Grasses Breeding Switchgrass Dawson, GA Molecular biology Toxin Research Management Economics Economics Ft. Collins, CO Harvest & Storage Switchgrass Quality C-Sequestration Tifton, GA Other grasses Temple, TX Peoria, IL Breeding Management Modeling Fermentation Conversion Sarat Sarath – Transatlantic Conference Lincoln Oct 17
  4. 4. USDA Identified Five Regional Biomass Research Centers Central-East (Lincoln, NE –ARS) Sarat Sarath – Transatlantic Conference Lincoln Oct 17
  5. 5. BIOMASS CONVERSION to Ethanol Lignin Critical component affecting convertability Most energy-rich Hemicellulose Cellulose CH3Glucose Xylan CH2 OH Ethanol Xylose Sarath – Transatlantic Conference Lincoln Oct 17
  6. 6. Breeding a better switchgrass for ethanol - its more than just lignin Less lignified tissues Bigger cells ~40 % greater ETOH High digestibility 3 cycles ~ 15 years 1 cycle ~ 5 years Base population Low digestibility A lot less ETOHMore lignified tissues Bioresource Tech. 102:9579-9585, 2011Smaller cells Sarat Sarath – Transatlantic Conference Lincoln Oct 17
  7. 7. Extramural Funding HighlightsDOE - The hunt for green every April: Factors affecting fitness in switchgrass – $1.18 million (2010-2012)NIFA - Mitigating insect herbivory of warm-season bioenergy grasses - gettingahead of the curve –In the early stages of insect evaluation –$990,000 (2011-2016)NIFA-CAP – Agro-ecosystem Approach to Sustainable Biofuels Production via the Pyrolysis-Biochar Platform – Regional project in IA, IL, IN, MN, NE, WI – ARS Lincoln serves as Co-PI on the Breeding and Management components of the grant – ARS Lincoln receives $540,000/year for 5 yearsAll three projects have intrinsic collaborations with University of Nebraska researchers Sarat Sarath – Transatlantic Conference Lincoln Oct 17
