DuPont Industrial Biosciences granted US patent for FERMASURE

By DuPont Industrial Biosciences | April 03, 2018

DuPont Industrial Biosciences announced today that it has been granted U.S. Patent 9,926,576 entitled “Prevention of Bacterial Growth in Fermentation Processes.” This patent issued by the U.S. Patent and Trademark Office covers the application of stabilized chlorine dioxide, the active ingredient in DuPont FERMASURE, to reduce microbial contaminations in ethanol fermentations.

Acid producing bacteria are a constant challenge during the ethanol fermentation process, with the potential to reduce yield, consistency and profitability for biofuels producers. When used during fermentation, FERMASURE controls bacterial growth without the need for antibiotics. DuPont scientists and technical service personnel have worked with the U.S. ethanol producers to validate the benefits of FERMASURE brand stabilized chlorine dioxide in both batch and continuous fermentation conditions.

“FERMASURE is an innovative technology, representing not just the best work of our scientists and researchers, but also the real-world value DuPont technologies deliver for our customers each day,” said Judy Underwood, global marketing director for grain processing at DuPont. “As a company committed to cutting-edge solutions, we’re thrilled to see this work recognized by the U.S. Patent and Trademark Office. DuPont will continue commercializing this effective, antibiotic-free microbial control solution with the additional intellectual property protection that this granted patent affords.”

Microbial control is a crucial part of ethanol production worldwide particularly as the demand for biofuels continues to grow. FERMASURE is just one of the innovative offerings, including enzymes and engineered yeast solutions, that DuPont offers to help ethanol producers improve their yield and profitability.
