Characterization

FRE_adhE is the transcriptional and translational regulatory element which contains the cassette of 5′ upstream region controlling the expression of the major fermentative gene adhE. For the function determination, we used the FRE_adhE to drive the synthetic 1-butanol production. And the plasmid piGEM2018-Module002 was constructed successfully(Fig. 1).

Fig. 1 piGEM2018-Module002

Theoretically, fermentation of 1-butanol will be triggered under anaerobic conditions because of FRE’s regulation. We detected the production of butanol in E. coli BL21(DE3) carrying the above plasmid by gas chromatography.

Fig. 2 The production of butanol determined using GC.

The result (Fig. 2) shows our fermentation regulatory element successfully worked.
