Green Technology

Dupont and Broin partner together in the growing biofuels industry, where they develop the next steps needed to bring cost-effective ethanol derived from corn stover to market.  Corn stover is corn stalks that remain after the corn has been harvested.  The corn stover is one of the largest available biomass sources not being used.  About one ton of corn stover is produced for every one ton of corn harvested.  So the partnership is targeting a plentiful and under-utilized raw material.  ...

...   "The Integrated BioRefinery technology will significantly increase the amount of ethanol per acre achievable by using both the corn grain and stover.  DuPont's first in class fermentation process, developed with its partners, allows high conversion of both C-6 glucose sugars and the difficult to ferment C-5 xylose sugars to ethanol at high yields.  The Integrated BioRefinery technology uses a microorganism called Zymomonas mobilis to make these conversions.  In nature, this organism lives in solutions of high sugar concentrations, such as those derived from fruits and the sugar sap of plants, and so is well-suited for highly efficient conversion of sugar.
