Amyris and Total Announce Successful Demonstration Flight With Renewable Jet
Fuel During Paris Air Show

First Demonstration Flight in Europe on Airbus Aircraft Underscores Partners'
Commitment to Achieving ASTM Certification

PARIS, June 20, 2013 (GLOBE NEWSWIRE) -- Amyris, Inc. (Nasdaq:AMRS) and Total
(Paris:TOTF) announced today a successful demonstration flight at the Paris
Air Show using a breakthrough technology that converts plant sugars into
renewable jet fuel.

The Airbus A321 aircraft powered by two Snecma CFM56 jet engines flew from
Toulouse to Paris with a blend of renewable jet fuel produced by Amyris and
Total. This demonstration flight was in support of the French Initiative for
Future Aviation Fuels, which seeks to produce and commercialize alternative,
renewable and sustainable aviation fuels in France in the coming years. This
was the second public demonstration flight with the Amyris-Total renewable jet
fuel. In June 2012, an Embraer E195 jet flew with the renewable jet fuel
produced from sugarcane in Brazil.

"This is a significant milestone in our strategic partnership with Total for
biofuels. From developing the world's leading synthetic biology platform to
producing and distributing renewable products globally, the Amyris-Total
collaboration demonstrates the power of partnerships to drive innovation and
deliver sustainable products," said John Melo, President & CEO of Amyris.
"Today's flight is another step closer in achieving ASTM certification, which
paves the way for the commercialization of our renewable jet fuel," Melo

"The air transport sector has an ambitious target: drastically reducing its
greenhouse gas emissions by 2050 while commercial flights and demand for jet
fuel will steadily grow. To that end, biofuels will play an important role
along with improved aircraft energy efficiency. This demonstration flight
illustrates the capacity of Amyris and Total to integrate, as of today,
aeronautical biofuels in a concrete and reliable way," said Philippe Boisseau,
President, Marketing & Services and New Energies and a member of the Executive
Committee of Total. "As one of the world's biggest suppliers of aviation fuel,
Total aims at widely offering this solution to airline customers. We are
confident that we will be able to achieve this within the coming years."

About the Renewable Jet Fuel

The Amyris-Total renewable fuel was produced using engineered microorganisms
that convert plant sugars into Biofene^®, Amyris's brand of renewable
farnesene, a long-chain, branched hydrocarbon. In December 2012, Amyris began
commercial production of Biofene at its industrial-scale production facility
in southeastern Brazil. Amyris uses Brazilian sugarcane due to its
availability, competitive cost, and the local industry's ability to meet
international sustainability standards.

In addition to supporting the aviation industry's goal of reducing greenhouse
gas emissions, the Amyris-Total renewable jet fuel is designed to be compliant
with Jet A/A-1 fuel specifications and outperform conventional
petroleum-derived fuel in a range of performance metrics, including fit for
purpose and greenhouse gas emission reduction, while maintaining performance
quality. Amyris and Total expect the fuel to be commercially available as
early as 2014, following approval by the ASTM International, the world's
leading fuel standard setting body.
