What is a Reporter?
It isn't enough to just be able to detect something - after the presence of naphthenic acids are confirmed by our promoter, we require some way for our bacteria to report back results that can be interpreted by an observer. Over the course of the project, Team Calgary considered three different reporter systems - colorimetric, fluorescent, and electrochemical.
Why Electrochemical?
Oilsands tailings ponds samples are difficult to work with for several different reasons. First of all, tailings ponds samples are murky, and can have greatly varying compositions from pond to pond. It would be difficult to obtain accurate colorimetric data from these samples, and it would be similarly difficult to readily observe fluorescence. Because an electrochemical response does not rely on being able to see anything, Team Calgary determined the electrochemical reporter to be ideal for this purpose.
Electrochemical reporters offer several advantages over visually-determined reporters. The signal is robust - environmental factors such as the presence of pollutants or sample turbidity do not affect the signal. Every molecule has a different oxidation potential - because we know the exact oxidation potential for our analyte, we can easily tell the difference between our desired signal and background noise.
