DuPont Launches SYNERXIA® Gemstone Yeasts for Ethanol

DuPont Nutrition & Biosciences has launched the SYNERXIA® Gemstone Collection of high-performance yeasts for the U.S. ethanol market. The new collection from the XCELIS® platform includes SYNERXIA® SAPPHIRE and SYNERXIA® RUBY designed for the unique needs of ethanol producers.

This marks the first time that DuPont has co-launched two high-yield yeasts. SYNERXIA® SAPPHIRE brings the most powerful combination of yield, robustness and enzyme expression in a yeast. It offers enhanced ethanol yield increase paired with revolutionary thermotolerance and infection robustness in fermentation and has been genetically engineered to withstand harsh stressors, while still finishing fermentation with ultra-low DP1.

SYNERXIA® SAPPHIRE has been engineered to provide a strong ethanol yield increase compared to conventional yeast and powers through fermentation finishing clean when ethanol producers encounter hot fermentations or severe infections. The product also expresses enough glucoamylase to displace up to 80 percent of the glucoamylase injected to fermentation. The yeast’s strong expression of the powerful glucoamylase offers reduced residual starch for many producers.

SYNERXIA® RUBY is the highest yielding yeast available today from the XCELIS® platform, delivering exceptional performance to producers via a patented PKL pathway and additional targeted genetic modifications. It produces less acetic acid compared to SYNERXIA® THRIVE GX and enables up to 65 percent glucoamylase reduction.
