Genencor mixes up enzyme cocktail to boost cellulosic ethanol production

International enzyme development firm Genencor, a division of Danisco A/S, has announced it's now mixing up the fourth enzyme cocktail in its trademarked Accellerase line. Called Accellerase Trio, Genencor says that this latest enzyme is designed to boost production of cellulosic ethanol from non-food feedstocks. More specifically, Accellerase Trio is an enzyme cocktail optimized to break down C5 and C6 sugars in biomass feedstocks, improving cellulosic ethanol yields by up to 20 percent over Genencor's previous enzyme, Accellerase Duet.
Enzyme costs and dosage requirements have presented a challenge for cellulosic ethanol producers. Since launching its Accellerase line back in 2007, Genencor has worked 'round the clock to improve its enzyme packages. It's worth pointing out that both Danisco A/S and Genencor just so happen to be subsidiaries of some mega-corporation that does business under the name DuPont.

Genencor Launches a Market-Leading Enzyme Product to Advance Cellulosic Biofuel Production Worldwide


Accellerase® TRIO Helps Reduce Ethanol Production Costs, Lowers Dosage And Offers Environmental Benefits

Palo Alto, California-Genencor today announced a product advancement, Accellerase® TRIO. This new product will enable biofuel producers to more cost-effectively manufacture cellulosic ethanol from a wide range of renewable nonfood feedstocks such as switchgrass, wheat straw and corn stover as well as from municipal solid waste.

"Second-generation biofuels offer important energy security, as well as economic and environmental benefits to countries such as the United States, China, India and European nations that import a majority of their oil," said Genencor CEO Tjerk de Ruiter. "Accellerase® TRIO can accelerate the commercial production of cellulosic biofuels in markets across the world, helping many countries and companies find a more sustainable alternative to petroleum."

Accellerase® TRIO allows for a low enzyme dosage to produce ethanol, helping to improve the economics of cellulosic biofuel production. Genencor has improved the effectiveness of converting biomass into sugars, a critical step in the production of cellulosic ethanol. With Accellerase® TRIO, Genencor provides a combined "cocktail" of enzymes all in one product to breakdown the glucan (C6) and xylan (C5) in the biomass feedstock into fermentable sugars, thus increasing the ethanol yield per unit of feedstock.

Ethanol producers will discover other benefits. Accellerase® TRIO works with a wide variety of renewable feedstocks, allowing producers to select nonfood crops and municipal solid waste that are abundant in their region to convert to ethanol or biochemicals. In addition, Accellerase® TRIO can help boost total production by lowering viscosity and enabling producers to process more biomass.

Accellerase® TRIO is the latest advancement in Genencor's award-winning Accellerase® product line that earned the "Frost & Sullivan 2009 New Product Innovation Award" for enzymes for biofuel production and also this year's "Sustainable Technology Award" at the World Biofuels Market conference in Rotterdam, the Netherlands.

Genencor's mission is to have a significant impact on the sustainability of every household globally – and its development of biobased enzymes for second-generation biofuels helps create a more sustainable future. According to the U.S. Department of Energy and the Center for Transportation Research, cellulosic biofuels have the potential to reduce greenhouse gas emissions up to 86 percent over gasoline.

While still in the early stages of development, cellulosic ethanol is expected to play a crucial role in providing transportation fuel in many parts of the world. In the U.S., Congress has set a goal of 36 billion gallons of renewable fuel to be produced by 2022, with much of that amount coming from second-generation ethanol.

Europe is requiring that 10 percent of all road transportation fuels come from biofuels by 2020, a mandate that focuses on next-generation technologies. China's 12th Five-year Plan places great emphasis on the investment and research of the country's ethanol fuel and reducing greenhouse gas emissions through cleaner fuels.

Genencor has a 25-year history in biofuels research and development. In 2007, Genencor was the first company to launch a commercial-scale enzyme for cellulosic ethanol production, Accellerase® 1000, and later the company introduced Accellerase® 1500 and Accellerase® DUET.
