Characterization by UiOslo_Norway 2019
This part was of special interest to our team. The part consists of homologs of the genes we used; crtE, crtB and crtI from Deinococcus radiodurans. BBa_K274120 has individual ribosomal binding sites for each individual enzyme. The part that we made had a single ribosomal binding site followed by all three genes in a single open reading frame. The first two genes had their stopcodons removed (see BBa_K2971004 and BBa_K2971010). Figure 1 shows the result of expressing BBa_K274120 in E.coli (BL21) for 24 hours. The red coloration in the induced pellet is caused by the presence of lycopene. The induced culture with BBa_K274120 produced significant amount of lycopene when compared to expression of BBa_K2971004 (figure 2).

Since the production of lycopene was so high in BBa_K274120 compared to our composite part we tired using the culture in a simple solar cell (figure 3). The design of the solar cell is comparable to a regular DSSC (see our design page).
Figure 2: Pelleted culture of E.coli expressing BBa_K274120 used in a simple solar cell Expression was induced in 2% arabinose We did not observe any detectable current from this solar cell.
