trans-β-Farnesene [(E)-β-Farnesene, CAS 18794-84-8] is a 15 carbon, long-chain, branched, unsaturated hydrocarbon. It offers unique physical properties and chemical reactivity for new materials.


Amyris’s trans-β-farnesene is the renewable building block for the market you want to create. Its molecular structure makes it unique and attractive as a scaffold for specialty chemical applications.

Other applications include:


  • Performance materials
  • Adhesives
  • Fragrances
  • Surfactants
  • Stabilizers
  • Oligomers and polymers
  • Resins
  • Foams, coatings and sealants
  • Emulsifiers
  • Vitamin precursors
  • Crop protection

Our Process

Amyris’s trans-β-Farnesene is produced through fermentation of sugars by yeast. Target genes are selected to change the yeast’s metabolism, converting the yeast from an ethanol-producing organism into a hydro-carbon producing organism.

Amyris’s platform enables the production of selected molecules at high purity levels. It also provides three distinct advantages over the existing sources: first, it efficiently produces compounds that can’t be made by chemical synthesis;


second, it replaces compounds typically derived from plant sources that can’t be extracted reliably; and third, it replaces compounds made from petrochemicals, with renewable compounds.

This technology platform is revolutionary in allowing commercially viable levels of production of the trans-β-Farnesene molecule.
