Presentation Transcript

  1. Environmentally and economically sustainable production of fuels and chemicals from sweet sorghum JohnErickson Jose Lopez Terry Felderhoff Lonnie Ingram Ismael Nieves Joe Sagues Elena Ten Frankie Tsui Amelia Dempere Chen Ling ArunSrivastava • Wilfred Vermerris • University of Florida Genetics Institute • Department of Microbiology and Cell Science

  2. Biofuel production from sweet sorghum in Florida • Stress tolerant (drought, heat) and limited input requirements compared to sugar cane • Minimal competition with food production • Ideal crop for transition from sugar-based to lignocellulosic biofuels • Compatible with sugarcane production • 7,000 L ethanol per hectare from juice

  3. Next-generation sweet sorghums: Sustainable production of fuels and chemicals from juice and bagasse CO2 chemicals fuels fermentation juice chemicals bagasse CBP pentoses fuels pretreatment fermentation hexoses saccharification chemicals Sweet sorghum lignin plastics nanotubes heat

  4. Improved sweet sorghum cultivars Commercial hybrid Five new sweet sorghum cultivars with higher sugar and biomass yield compared to currently available germplasm Excellent disease resistance New UF cultivars

  5. Lignin nanotubes for biomedical applications membrane Lignin base-layer Deposition of DHP liner 15 μm Dissolution of membrane 109pores cm-2 109nanotubes cm-2 Caicedo et al. (2012) Nanotechnology; Ten et al. (2014) Biomacromolecules
