Abstract
The invention relates to the production of one or more terpenoids through microbial engineering, and relates to the manufacture of products comprising terpenoids.
Claims25
A method for making a product containing valencene or a derivative thereof, the method comprising:
- providing an Escherichia coli (E. coli) that produces isopentyl pyrophosphate (IPP) and dimethylallyl pyrophosphate (DMAPP) through an upstream methylerythritol pathway (MEP) and converts the IPP and DMAPP to valencene through a recombinantly expressed downstream synthesis pathway comprising Farnesyl Diphosphate Synthase and Valencene Synthase;
- and
- culturing the E. coli to produce the valencene or derivative thereof, wherein the accumulation of indole in the culture is controlled to below 100 mg/L to thereby increase production of valencene or derivative;
- and
- incorporating the valencene or derivative into a product.
