Bio-ethanol has paved the way as a renewable alternative fuel that can help bring energy stability and economic growth through the displacement of oil and reduction of green house gas emissions. Ethanol is blended in approximately 80% of U.S. gasoline and in 2009 production was estimated at 10.6 billion gallons. Global production exceeded 19.5 billion gallons of ethanol in over 40 countries. The growing rise in ethanol demand has led to new generations of technologies. At Verdezyne, we are developing technologies that address the increased global demand for sustainable fuels.
We have developed and are engineering proprietary metabolic pathways in yeast for enhanced conversion of hexose (C6) and pentose (C5) sugars to ethanol. It is our goal to bring superior yeast to market that will deliver improved profitability and sustainability to ethanol producers.
By addressing the need for improved ethanol fermentation economics we are engineering novel pathways into yeast that increase the fermentation yield and productivity from hexose sugars, regardless of their source. We have engineered and demonstrated this by boosting productivity and yield per unit of glucose compared to currently available strains.
Robust fermentation of C5 sugars in biomass remains a key bottleneck for commercializing the next generation cellulosic ethanol process. By applying the latest advances in synthetic biology, we are engineering proprietary genes that accelerate C5 fermentation to enable cost competitive cellulosic ethanol.
