The integration of the partners' individual technology platforms will
combine:
-- A differentiated pretreatment process developed by DuPont through
its collaboration with the U.S. Department of Energy National
Renewable Energy Laboratory (NREL) that allows for reduced capital
costs;
-- Enzyme technologies and production platforms enabling high
biomass-to-sugars conversion rates developed by Genencor, a leader
with world-class capabilities in the discovery, optimization and
production of enzymes for cellulose conversion;
-- A proprietary ethanologen, also developed through the DuPont-NREL
collaboration, based on Zymomonas mobilis. This ethanologen has the
ability to convert sugars contained in the feedstock into high
yields of ethanol with fewer byproducts, and;
-- The companies' joint engineering capabilities in process integration
and facility design.
Since 2000, the U.S. Department of Energy has supported the efforts of DuPont and Genencor through multiple grants totaling more than $60 million for the development of pretreatment processes, advanced ethanol conversion organisms and improved enzymes.
DuPont and Genencor have a history of successful collaboration. In 1995
the companies partnered to develop the fermentation biocatalyst that
produces Bio-PDO(TM) propanediol, one of the first commercial-scale
industrial applications of metabolic engineering designed to make a 100
percent renewably sourced material from corn starch. Today, the product is
manufactured by DuPont Tate & Lyle Bio Products, LLC in Loudon, Tennessee,
U.S. DuPont and Genencor were recognized by the U.S. Environmental
Protection Agency in 2003 with the Presidential Green Chemistry Challenge
Award. Last year, leading scientists and engineers from DuPont,
