DuPont introduces new yield-increasing fermentation system for ethanol production

DuPont Industrial Biosciences has launched a new fermentation system to help ethanol producers improve their yields and decrease sugar levels in their product.

The DuPont Synerxia system, introduced at the Fuel Ethanol Workshop in Milwaukee, Wisconsin, increases yields by up to 2%, while lowering total sugar levels at drop by up to 25%.

The system includes Synerxia Prime ADYT, a bioengineered yeast paired with the world’s only commercial dry trehalase.

Compared to cream yeast, the DuPont active dry yeast requires no special storage or handling.

The system also includes Synerxia Prime LC, a new glucoamylase blend that delivers three times the debranching activity of conventional glucoamylase, the company says.

The glucoamylase included in the Synerxia system liberates more glucose for the yeast to ferment, improving ethanol yield.
