Gevo Awarded Foundational Patent for Commercially Viable Isobutanol Production

ENGLEWOOD, Colo., April 30, 2013 (GLOBE NEWSWIRE) -- Gevo, Inc. (Nasdaq:GEVO)
announced today that it has been issued a new patent, U.S. Patent No.
8,431,374 ('374 Patent), covering the foundational methods for low-cost
isobutanol production at commercially relevant titer, productivity, and
yields.

"This is a milestone achievement toward our goal of making commercial
isobutanol a reality," said Brett Lund, Gevo's executive vice president and
general counsel. "Titer, productivity, and yield are three of the key metrics
needed to sustain an economically viable process for isobutanol production.
This patent broadly protects methods of producing isobutanol at economically
viable levels. Prospective producers of isobutanol cannot achieve commercially
viable production without access to our '374 Patent."

"This patent significantly strengthens Gevo's intellectual property position
and reinforces our unmatched ability to obtain dramatic improvements in
commercially-viable isobutanol production," added Lund. "We will continue to
take the steps necessary to protect and maintain the integrity of our
industry-leading technology."

This is the tenth U.S. patent granted to Gevo within its biocatalyst
portfolio. Gevo's patent portfolio includes more than 450 patents and patent
applications.
