  1. More Efficient Bioethanol from Poplar Wood?Tues. 22nd May 2012, EnergyAway Day, Chilworth Manor Adrienne Payne

  2. What is bioethanol? Solar Energy and Carbon Dioxide Carbon Dioxide Biomass Harvesting CO2 Biofuels CO2 Pre-processing CO2 Enzymes break cellulose down into sugars and microbes ferment sugars into ethanol

  3. Bioenergy -concerns • Greenhouse gas balance? • Biodiversity? Loss of species? • Food crop displacement and prices? • Other indirect effects… tropical rain forests? Soil carbon? • Societal concerns? GM? • Landscape-scale changes? • Water use and management? Biofuelsgood?Biofuelsbad?

  4. Why is poplar the ideal bioenergy tree? Full genome sequence (15 Sept 2006) Small genome (similar to rice) Diversity of species Fast growing and perennial Clonal Transformation system Genetic collections and molecular maps Activation tagged populations EST and BAC libraries Genomic and post-genomic tools
