Exponential phase transcriptional control device

To implement an exponential phase dependent transcriptional control device (BBa_J45994), we combined the stationary phase transcriptional control device (BBa_J45992) with a transcriptional inverter device. The resulting composite device produces a high (ON) transcription signal in exponential phase. In stationary phase, the osmY promoter drives expression of the repressor leading to a low (OFF) transcriptional signal at higher cell densities.
