ABSTRACT:
Method for amperiometrically measuring the bacterial content of liquids in a bioelectrochemical cell wherein the mediator is initially oxidized in the cell, then brought into contact with a capturing system containing the bacteria of the sample, resulting in a first response at the electrodes, and finally brought into contact again with the capturing system after the bacteria present have been killed, producing a second response due to the interfering substances, which is subtracted from the first response. An apparatus is also provided for implementing this method.
