Wow!! By lighting bacteria, a refreshing scent stars filling the room. In the dark, the light sensing E.coli will turn orenge. With the red light on, the color of E.coli fades out, and aroma is produced instead.

aroma

Firstly,we are going to make E.coli that smell good!

We are going to get gene that codes these products synthases.

light receptor

Secondary,We are going to make a light receptor that react different wavelength.

PCB reacts redlight (that is about 660nm). If we change PCB to PΦB and PEB , the absorption wavelength shifts 15nm respectively.

carotenoid

We are going to use the EBIY. EBIY produces ricopen. That puts out orange color.
