Gevo, Inc., a leading renewable chemicals and next-generation biofuels company, said today that it has been issued a new patent, US Patent No. 8,273,565, entitled “Methods of Increasing Dihydroxy Acid Dehydratase Activity to Improve Production of Fuels, Chemicals, and Amino Acids.”
The new patent covers suppression of a glutaredoxin protein called GRX3. In combination with other Gevo patented technologies, deletion of GRX3 significantly increases the production of isobutanol by yeast cells.
Gevo’s patent-protected, capital-light business model converts existing ethanol plants into biorefineries to make isobutanol. This versatile chemical can be directly integrated into existing chemical and fuel products to deliver environmental and economic benefits. Gevo is now producing isobutanol at its first commercial facility in Luverne, Minn., and has a marquee list of partners including Coca-Cola, Sasol, and LANXESS, among others. Gevo is committed to a sustainable biobased economy that meets society’s needs for plentiful food and clean air and water.
