  1. High Energy BioGas/Diesel Steve Briggs UCSD

  2. Try Corn Alcohol Gasoline! April 1933 Lincoln, Nebraska

  3. Fuel Ethanol yeast corn grain starch sugar cane glucose sugar ethanol sugar beet fermentation C4 grasses trees cellulose municipal waste

  4. Ethanol fuel qualities • Good • Easy to make using existing technology from the brewing industry • Bad • Low energy density (70% gasoline) • Corrosive • Low product yield from fermentation (12% v/v)

  5. Ethanol vs. Gasoline and Petrodiesel Composition OH Ethanol 7C 16 C 8C 5C 8C Paper and Fibre Research Institute Trondheim, Norway

  6. Biosynthetic gasoline/diesel • Gasoline C5-C9 • Diesel C9-C16 • Biosynthetic gasoline/diesel C10 • Alkane • Monoterpene • Produced in bacteria (ethanol is made in yeast)

  7. Bacterial Biofuel Synthesis • Bacteria grow faster than yeast • Bacteria can be engineered to produce complex products like alkanes and monoterpenes • We have discovered a new control mechanism called TEnBox that enables products to be made in bacteria at 50-fold higher levels than was previously possible • We are using TEnBox to make biofuel in bacteria at lower cost and higher yield than ethanol made in yeast

  8. Ethanol 70% energy density Corrosive Expensive Made from yeast Based on traditional brewing technology Utilizes sugar from corn starch, sugarcane, sugarbeet, or cellulose BioGas/Diesel 100% energy density Non-corrosive Inexpensive Made from bacteria Based on TEnBox technology Utilizes sugar from corn starch, sugarcane, sugarbeet, or cellulose Summary
