Genencor, a division of Danisco A/S, introduced Feb. 15 Accellerase® DUET at the Renewable Fuels Association’s 15th Annual National Ethanol Conference in Orlando, FL.

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® 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® DUET builds on the advances in beta-glucosidase and cellulase activity previously made by Accellerase® 1500.

These additional improvements allow Accellerase® DUET to achieve higher sugar and biofuel yields, often at 3-fold lower dosing, and to be feedstock- and pretreatment- flexible.

Accellerase® 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.

Biography of Dr. Aaron Kelley

Dr. Aaron Kelley is Senior Engineer, Biomass Applications for Genencor, a Danisco Division.

Upon graduation from the University of Minnesota with his doctorate, Aaron began work at Genencor International, now a division of Danisco, in 2000.

He started work on the subcontract from the National Renewable Energy Labs (NREL) to decrease the cost of cellulase enzymes for biomass degradation.

Aaron then moved to the Global Engineering Organization where he helped transfer many of the developments from the NREL work to our manufacturing sites.

In 2004, Aaron took a position as Technology Manager at our Cedar Rapids, Iowa manufacturing plant.

There he led the process engineering team to improve existing manufacturing processes and facilitate transfer of new products from R&D.

In 2007, Aaron returned to Palo Alto to join the Biomass Applications Group with the aim of launching enzyme products for biomass applications.
