Genencor Introduces Latest Generation of Enzymes for Biomass Hydrolysis for Cellulosic Ethanol Production

Genencor, a division of Danisco A/S, introduced Accellerase DUET at the Renewable Fuels Association’s 15th Annual National Ethanol Conference last week in Orlando, Fla. This product is the latest generation in the company’s line of enzymes used to convert biomass into sugars, for subsequent production into cellulosic ethanol and other advanced biofuels.

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 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.

Novozymes also introduced its latest generation of enzyme technology at the RFA national conference. (Earlier post.)



Cellulose biofuels through fermentation would be fine. Since you do not have DDG left, you could take the remains and gasify them to make more fuel.

One of the interesting facts about Florida is that they have huge tons of orange peels from their juice industry. Go ahead and break those down and gasify the remains.
