Turbidimetry is one of the traditional methods used in microbiology to obtain bacterial growth curves. Electrical impedance has been proposed as a convenient alternative. Our objective was to implement simultaneously both methods while separating the three components (bulk resistance, interface resistance and interface capacitive reactance) from the total impedance measured during growth between the two electrodes immersed in the medium, based on previously obtained results.
