Making Farnesene Widely Available to Accelerate Development of New Renewable
Products and Applications

EMERYVILLE, Calif., April 4, 2014 (GLOBE NEWSWIRE) -- Amyris, Inc.
(Nasdaq:AMRS), a leading synthetic biology innovator and renewable products
company, today announced it has begun selling Biofene®, Amyris's brand of
farnesene, a long-chain branched hydrocarbon, online at By
making initial quantities of its building block molecule available to a
broader audience, Amyris seeks to expand Biofene's use beyond the commercial
applications the Company and its partners are already developing.

"We want to make our renewable hydrocarbon building block molecule widely
available to create new products and applications. We expect to accelerate
Amyris's commercialization by simplifying access to high-purity, renewable
farnesene," said John Melo, Amyris's President & CEO.

Amyris is now selling Biofene through its website in 1 kilogram lot sizes
(about a quarter of a gallon). Biofene (trans-beta-Farnesene, E,E-Farnesene,
CAS 18794-84-8) is a 15 carbon, long-chain, branched, unsaturated hydrocarbon
manufactured by the fermentation of plant-sugars using Amyris's engineered

"This innovative approach is complementary to our current strategy for growing
existing products – such as our Neossance™ Squalane, renewable fuels, base
oils and monomers for the tire industry, all of which are produced from our
farnesene," concluded Melo.

Biofene offers unique physical properties and chemical reactivity for new
materials and for a variety of applications, including adhesives, surfactants,
resins, coatings, vitamin precursors, performance materials and crop
protection. Farnesene is an essential oil that is found in small quantities in
some plants such as apples, but Amyris has developed a proprietary technology
to produce farnesene at industrial scale.
