Steps Involved in the Production of Bacterial Photographs • Mix 1 million engineered E. Coli into a warm molten solution of a growth medium. • Cast the solution into a common petri dish and set it at room temperature to ensure it solidifies into a film. • Place the film inside an incubator and shine a focused image of light onto the surface of the film. • Grow the bacteria for approximately 12 hours. • After the 12 hours, remove the bacterial film from the incubator.
2 Component System Two component signaling pathway The sensor and the responder molecules The communication between the two component signaling pair occurs via a three-reaction “phosphorelay”
Phosphorelay http://openwetware.org/wiki/20.109(F12):_Mod_2_Day_2_Measuring_system_performance • Sensor • Autophosphorylation • Histidine protein kinase • Phosphorylation of responder • Regulation of relevant genes • Reset the system

Expectations, Problems, and Testing • Potential Problems • Longer activation time than expected • Kill switch may not function • Frequency may not be accurate • Room to Improve? • A gene that is more sensitive to sound • a protein or operon that produces a greater amount/power of luminescence
