Genencor Releases new Cellulosic Ethanol Enzyme

Genencor, a division of Danisco A/S, has launched Accellerase 1500, the next generation of its cellulosic ethanol enzyme product. Genencor introduced the product at the Renewable Fuels Association (RFA) National Ethanol Congress in San Antonio, Texas this month.

“We’re on course to fast-track commercialization of cellulosic ethanol,” says Philippe Lavielle, senior vice president of Business Development at Genencor. “Accellerase was a breakthrough in the industry. Now, by launching this improved enzyme product, we reach another important technical milestone toward commercial-scale production of transportation fuel and other biochemicals from renewable, non-food feedstocks.”

The company said that Accellerase 1500 will lower a major cost hurdles to producing ethanol or biochemicals from cellulosic feedstocks, such as corn stover, sugarcane bagasse, wood chips, wheat straw and switchgrass. Accellerase is part of the hydrolysis step of converting biomass to ethanol or other biochemicals. In this step, plant material is broken down into sugars for fermentation to ethanol. The product is based on Genencor’s patented gene expression technology.

Genencor supplies Accellerase as part of its dual-strategy to drive forward the cellulosic ethanol industry, which includes its dedicated enzyme business, and its joint venture DuPont Danisco Cellulosic Ethanol LLC, which develops and provides integrated technology packages for biomass ethanol production.
