The Immittance Response of Escherichia Coli Bacteria

In this study the ac small-signal electrical data are obtained for the sterile BHI and E. Coli bacteria suspended BHI material systems to extract an equivalent circuit model via Bode plot in conjunction with the complex plane plot. It is observed that the non-blocking conductive nature of the underlying operative electrical paths between the two opposite electrodes across the sample (material system) exist satisfying dc condition of the equivalent circuit model. Thus, the proposed equivalent circuit model verifies the existence of the shunt resistance that provides a meaningful representation of the material system. The non-Debye behavior is not addressed as this work is emphasized to establish correct equivalent circuit model.
