摘要 | Isoprenoids are important fine chemicals as material monomers, advanced fuels and pharmaceuticals. A variety of natural isoprenoids can be synthesized by engineered microbial strains. This work established a process by dividing the current isoprenoid pathway into the upstream fermentation process, from sugar to mevalonate (MVA), and the downstream process, from MVA to the target isoprenoids. The results showed that significant differences existed in the process conditions between the upstream and downstream fermentations. After individually optimizing the process conditions, the upstream MVA production (84.0 g/L, 34.0% and 1.8 g/ L/h) and downstream isoprene production (11.0 g/L and 0.23 g/L/h) were greatly improved in this two-step process. Flask fermentation experiments also confirmed that two-step route can significantly improve the sabinene titer to 150 mg/L (6.5-fold of the sabinene titer in an earlier flask study of our lab). Therefore, the two-step route proposed in this study may have potential benefits towards the current isoprenoids production directly from glucose. The high titer and yield of MVA indicate that MVA has great potential to be more broadly utilized as starting precursor in synthetic biology. |
