As a first stage toward the development of an impedimetric biosensor to quantify viable bacterial cells, this work defines the relationships between microbial growth and impedance changes associated with acidification of the culture medium. Escherichia coli bacterium was used as a model of a common pathogenic bacterium found in a foodstuff. Impedance was measured at a fix frequency of 10kHz using...
It is well known that the metabolic activity of some microorganisms results in changes of pH of the culture medium, a phenomenon that can be used for detection and quantification of bacteria. However, conventional glass electrodes that are commonly used for pH measurements are bulky, fragile and expensive, which hinders their application in miniaturized systems and encouraged to the search for alternatives...
