In vivo expression of our devices in E.coli MG1655
Our preliminary research indicated that carotenoids production in E.coli TOP10 was very weak. We decided to use another strain, E.coli MG1655, for in vivo expression of our devices. The amount of carotenoids produced became visibly higher. Generally, the colour became visible after incubation for about 12 hours.

| E.coli MG1655 transformed with K274110 and grown on agar plate overnight. | Cell pellet of E.coli MG1655 transformed with K274210 (from 20mL LB culture at 37°C for 24 hours). |
