Ethanol Sensor

This graph shows the fluorescent response of cell cultures containing two plasmids: pBAD33bb: exaDE and PexaA: TagRFP in pSB1A2 (pEtRv2.1). The fluorescence of the system at varying ethanol concentrations was normalized to the optical density of their respective cell culture. The cells’ fluorescence was measured over a range of ethanol concentrations from 0%-5% EtOH. This ethanol sensing system is “turned on” or induced in the presence of arabinose by the PBAD promoter. The blue data points on the graph represent the fluorescence of cell cultures without any arabinose and therefore the ethanol sensor is uninduced; the red data points represent the fluorescent response of the induced system in the presence of .2% arabinose.
