And then E.coli said, "Let there be light!"

Proteorhodopsin, The Savior

Proteorhodopsin belongs to the class of Bacterial rhodopsin, membrane proteins which are photon driven proton pumps. And its potential application ranges from increased metabolic activity to usage as a solar cell. After weeks of literature survey and brainstorming we came up with the following novel applications of Proteorhodopsin in Synthetic Biology.

1.Light based Screening for Transformants (Light Saber)
2.Enhancing Recombinant Protein synthesis (Super active Bacteria)
3.Improving Hyularonic Acid Production (E.plasti)
4.Increase in Biofuel production (Butanol biosynthesis)
5.Light-switch life form (Photographic film)

In other words, we are giving bacteria the ability to utilize the cheapest, cleanest and the most abundant substrate - a photon, to accomplish what a normal bacteria can't. The possibilities are limitless.
