제목 Direct CO2 conversion to α-farnesene, a precursor of high-performance polymer and biodiesel, using engineered Synechococcus elongatus PCC 7942
초록 Solar-to-chemical and solar-to-fuel production from CO2 have been developed using engineered microorganisms that assimilate CO2 and convert target chemicals and fuels. Herein, Synechococcus elongatus PCC 7942, a model cyanobacterium, was engineered to produce α-farnesene from CO2. Due to the lack of an endogenous activity of farnesene synthase (FS) in the wild-type cyanobacterium, we metabolically engineered S. elongatus PCC 7942 to express heterologous FS from either Norway source or apple fruit. To enhance α-farnesene production, an optimized methylerythritol phosphate (MEP) pathway was introduced in the farnesene-producing strain to supply farnesyl diphosphate. We demonstrated direct conversion of CO2 to α-farnesene using metabolically engineered cyanobacteria at the highest rate reported thus far (4.6 ± 0.4 mg/L in 7 days). This work was supported by Korea CCS R&D Center (KCRC) and Basic Science Program funded by NRF.
