Electrochemical based quantification of bacterial growth in media using square wave voltammetry and low cost screen printed electrodes

A novel method for determining the yield of bacterial growth using square wave voltammetry and screen printed electrodes is described here. This procedure was shown to be a reliable and accurate way to quickly determine the level of bacterial growth within culturing media and these results suggest that the combination of such sensors and the application of square wave voltammetry is suitable for applications such as within a bioreactor where the rapid determination of bacterial growth may be necessary.
