Genencor Introduces Accellerase(R) DUET

A Breakthrough Enzyme Product for Cellulosic Biofuels Development

PALO ALTO, California, February 15 - Genencor, a division of Danisco A/S, today introduced Accellerase(R) DUET
at the Renewable Fuels Association's 15th Annual National Ethanol Conference
in Orlando, Fla. This product is the latest generation in the company's line
of enzymes used to convert biomass into sugars, a critical step in the
production of cellulosic ethanol and other advanced biofuels and biochemicals
from non-food feedstocks.

"Genencor has a long tradition of commitment to addressing the need for
alternative, renewable fuels to help combat climate change," says Philippe
Lavielle, executive vice president of business development for Genencor. "The
renewed commitment earlier this month by the Obama Administration to support
the rapid development of renewable fuels is encouraging and exciting. With
more than 10 years of scientific investment in this area and a world class,
global manufacturing infrastructure, Genencor is now ready to support the
fast deployment of cellulosic biofuels. Accellerase(R) DUET is set to become
the standard that this industry is looking for in terms of cost and
performance."

With improved overall hemicellulase activity, Accellerase(R) DUET builds
on the advances in beta-glucosidase and cellulase activity previously made by
Accellerase(R) 1500. These additional improvements allow Accellerase(R) DUET
to achieve higher sugar and biofuel yields, often at 3-fold lower dosing, and
to be feedstock- and pretreatment-flexible. Accellerase(R) DUET employs a
whole broth formulation, which provides nutrients for fermentative organisms
and lowers the chemical load introduced into our customers' processes. Higher
performance at lower dose will lead to significant improvements in enzyme
cost in use for producers, which is critical to enable the cellulosic
biofuels industry.

Accellerase(R) DUET builds on Genencor's 25-year history of biofuels
research and a portfolio of patented enzyme technologies.

Genencor supplies the Accellerase(R) product line as part of its strategy
to drive the cellulosic ethanol industry forward. It is a critical component
of Danisco's two-pronged approach, which includes its dedicated Genencor
biomass enzyme business, and its joint venture DuPont Danisco Cellulosic
Ethanol LLC (DDCE), which develops and provides integrated technology
packages for biomass to ethanol production.
