We created and combined the zeaxanthin producing strain and with a plasmid containing the extended crocin pathway which gave us an E.coli strain including the entire production pathway from FPP to crocin. In the end, we were able to identify, create and extensively characterize the pathway for crafting crocin and confirm that modern production of crocin in E.coli is red-y.

The three enzyme BioBricks in the zeaxanthin-crocin pathway was assembled to one plasmid using 3A assembly(link 3A assembly protocol) and was inserted into the zeaxanthin producing E.coli strain using electroporation(link Electroporation protocol). The color of the colonies changes at each addition of another enzyme construct (another step in the crocin pathway). This is an indication that something is indeed happening with the bacterial production when we introduce our pathway steps, see figure X.
