JBEI researchers discover bisabolane-to-diesel pathway

Bisabolane is part of the terpene class of chemical compounds found in plants, and although traditionally used in fragrances and flavorings, a team of researchers at the U.S. DOE’s Joint BioEnergy Institute has discovered how to utilize bisabolane as an alternative to No. 2 diesel.

The research team, led in part by Taek Soon Lee, director of JBEI’s metabolic engineering program, genetically engineered two different microbes, E. coli and Saccharomyces cerevisiae, creating a new mevalonate pathway to overproduce a chemical compound called farnesyl diphosphate (FFP), which, when treated with enzymes can then be synthesized into terpene. Using the same microbes and the same pathway, the team created bisabolane as well, based on the mevalonate pathway that increased the biosynthesis ability in the microbes.
