Accellerase™ 1000 is launched at the Cellulosic Ethanol Summit in Washington, DC
Genencor, a division of Danisco A/S, announced on Oct. 15, a new product, Accellerase™ 1000, the first ever commercially available biomass enzyme developed specifically for second generation biorefineries.
Accellerase™ 1000 contains a potent complex of enzymes that reduces complex lignocellulosic biomass into fermentable sugars -- an indispensable step for the production of cellulosic ethanol. . . .
Highlights of Accellerase benefits
- Enhanced saccharification performance on a variety of feedstocks.
- Ability to operate in simultaneous saccharification and fermentation (SSF) processes, two step sequential hydrolysis and fermentation (SHF) processes or hybrids of the two.
- High ß-glucosidase activity to minimize residual cellobiose, which may lead to a higher saccharification and ultimately to a faster ethanol fermentation. Yields may also be improved.
- Unclarified product. The remaining nutrients from enzyme production are available to the yeast in addition to the fermentable sugars produced by saccharification.
- Minimal formulation to ensure that enzyme formulation chemicals do not interfere with saccharification carbohydrate profile analysis or subsequent yeast fermentation. . . .
Commercial interest in second generation biorefineries, driven in part by government policies to reduce the emission of greenhouse gases and increase energy independence, has accelerated over the past two years in the USA and around the world. Accellerase™ 1000 will fill a large unmet need for reliable biomass enzyme supply to pilot and demonstration plant developers who are actively working on process development, scale up and integration.
Accellerase™ 1000 is the first in what the company expects to be a family of products tailored to different biomass feedstocks and system conditions. The key features that are expected to be important at commercial scale are already built into this first product.
“The biofuels industry is at an inflection point with the development of cellulosic ethanol plants at the pilot and demonstration scale,” said Jack Huttner, vice president of biorefinery business development. “Every biorefinery developer needs to know how enzymes will work in their system. This product aims to address that need and to start a dialogue with potential partners about customized solutions and supply at the industrial scale.” . . .
Genencor has been developing its biomass enzymes for well over 10 years. The effort was partially supported by contracts with the US Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL).
Supposedly good new for cellulosic ethanol industry. The comment in quotes makes me wonder whether this product is cost effective or whether more development is required for individual crops. It sounds to me that the product is not truly commercial, but a ploy to get developers interested in their products. On Sept 20 the company announced price increases for their "saccharification product line by 10-15% effective October 15th, 2007 and as current contracts expire." This is a different product, but it makes you wonder.
On their website they make the followiing statement instead of the first point of their benefits in the press release:
Enhanced saccharification performance on a range of feedstocks - sugar cane bagasse, corn stover, softwood pulp.
I wonder why the difference, certainly these specific feedstocks are essential to the success of the cellulosic ethanol industry. But they leave out wood chips and switchgrass which are perhaps more desirable. There may be a logical progression from easier to handle feedstocks to more difficult ones.
