  1. Introduction to Green Tech America, Inc.(GTA) September 2009

  2. The engine for cellulosic ethanol and green chemicals Green Tech America, Inc.(GTA) Dr. Nancy Ho Founder & President www.greentechamerica.com 3495 Kent Avenue, Suite P100 West Lafayette, IN 47906 Phone: (765) 588-3834; (765) 463-3077

  3. Mission Statement Green Tech America is commercializing an engineered yeast for producing low cost renewable fuel, ethanol, from cellulosic biomass.

  4. Why ethanol from cellulosic biomass? Cellulosic biomass (including wood, grasses, agricultural residues, etc.) is the world’s most abundant renewable resources in the world.

  5. Composition of all types of cellulosic biomass Cellulose 45% Hemicellulose25% Other 5% Lignin 25%

  6. Cellulose and hemicellulose polymers from cellulosic biomass can be converted to a mixture of sugars containing nearly 50-60%glucose and 30-40%xylose.These sugars should be fermented to ethanol by microorganisms, most ideally by the baker’s yeast.

  7. Why use engineered yeast?The original yeast can only ferment glucose, but not xylose

  8. The solution Dr. Ho’s breakthrough engineered yeast developed at Purdue University is able to effectively co-ferment bothglucose and xylose to ethanol. The yeast is widely known as the Ho-Purdue Yeast.

  9. The MostEffectiveMicroorganism The breakthrough strategy plus several other innovative approaches used for engineering the yeast have made the Ho-Purdue Yeast greatly efficient for cellulosic ethanol production. It has been validated by several companies to be the current most effective microorganism for cellulosic ethanol production.

  10. The New Co-products Producing Yeasts In addition, to market the original Ho-Purdue Yeast and facilitate cellulosic ethanol producers to produce cellulosic ethanol, GTA has also made the Ho-Purdue Yeast able to produce various high-value co-products during cellulosic ethanol production. These new co-products producing yeasts will make the production of cellulosic ethanol much more profitable.

  11. The Ho-Purdue Yeast Produces 30-60% more ethanol from cellulosic biomass Fermentation with Ordinary Yeast 48-60 Gallons of Ethanol Pretreatment And Hydrolysis processes Feedstock 1 dry ton Cellulosic Biomass 80-100 Gallons of Ethanol Fermentation with Ho-Purdue Engineered Yeast

  12. Fermentation of high concentrations of glucose and xylose by Ho-Purdue Yeast

  13. Fermentation of High concentrations of glucose by the Ho-Purdue Yeast 13

  14. Other important goals and innovations Making farmers, particularly corn farmers, and corn ethanol producers more profitable Converting CO2 produced during ethanol production to useful products

  15. A few selected recognitions for Dr. Nancy Ho

  16. 2006, Dr. Ho was named by the distinguished Senator Dick Lugar as an Energy Patriot

  17. January 23, 2007, Dr. Ho was invited to attend President Bush's State of the Union Address in honor her work for cellulosic ethanol.

  18. January 31, 2007, President Bush sent Dr. Ho a letter to thank her for attending his State of the Union Address and for her commitment to fostering the development of renewable sources of energy.
