Microbial engineering for the production of chemical and pharmaceutical products from the isoprenoid pathway
The invention relates to the production of one or more terpenoids through microbial engineering, and relates to the manufacture of products comprising terpenoids.
1. A method for making a product containing patchouli alcohol, or 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 patchouli alcohol through a recombinantly expressed downstream synthesis pathway comprising farnesyl diphosphate synthase and patchoulol synthase; and
culturing the E. coli to produce the patchouli alcohol, or derivative thereof, wherein the accumulation of indole in the culture is controlled to below 100 mg/L to thereby increase production of patchouli alcohol or derivative; and incorporating the patchouli alcohol, or derivative thereof, into a product.
2. The method of claim 1 , wherein the product is a fragrance product, a cosmetic, a cleaning product, or a soap.
3. The method of claim 1 , wherein the product is an insecticide, pesticide, or pest control agent.
4. The method of claim 1 , wherein accumulation of indole in the culture is controlled by balancing the upstream MEP pathway with the downstream terpenoid synthesis pathway.
5. The method of claim 1 , further comprising measuring the amount or concentration of indole continuously or intermittently.
6. The method of claim 1 , wherein accumulation of indole in the culture is maintained to below 50 mg/L.
7. The method of claim 1 , wherein accumulation of indole in the culture is maintained to below 10 mg/L.
8. The method of claim 1 , wherein the patchouli alcohol or derivative is produced at 10 mg/L or more.
9. The method of claim 1 , wherein the patchouli alcohol or derivative is produced at 100 mg/L or more.
10. The method of claim 1 , wherein the E. coli has additional copies of one or more of the dxs, idi, ispD, and ispF genes of the MEP pathway.
11. The method of claim 10 , wherein the E. coli has a heterologous dxs-idi-ispDF operon.
12. The method of claim 1 , wherein the E. coli further expresses a P450 enzyme.
13. A method for making patchouli alcohol, or 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 patchouli alcohol or derivative through a recombinantly expressed downstream synthesis pathway comprising farnesyl diphosphate synthase and patchoulol synthase; and
culturing the E. coli to produce the patchouli alcohol, or derivative thereof, wherein the accumulation of indole in the culture is controlled to below 100 mg/L to thereby increase terpenoid production; and recovering the patchouli alcohol, or derivative thereof.
14. The method of claim 13 , wherein accumulation of indole in the culture is controlled by balancing the upstream MEP pathway with the downstream terpenoid synthesis pathway.
15. The method of claim 13 , further comprising, measuring the amount or concentration of indole continuously or intermittently.
16. The method of claim 13 , wherein accumulation of indole in the culture is maintained to below 50 mg/L.
17. The method of claim 13 , wherein accumulation of indole in the culture is maintained to below 10 mg/L.
18. The method of claim 13 , wherein the patchouli alcohol or derivative is produced at 10 mg/L or more.
19. The method of claim 13 , wherein the patchouli alcohol or derivative is produced at 100 mg/L or more.
20. The method of claim 13 , wherein the E. coli has additional copies of one or more of the dxs, idi, ispD and ispF genes of the MEP pathway.
21. The method of claim 13 , wherein the E. coli has a heterologous dxs-idi-ispDF operon.
22. The method of claim 13 , wherein the E. coli further expresses a P450 enzyme.
