An automated whole cell biosensor system was developed by integration of immobilized microbial cells in a flow-through system with screen-printed flow-through electrodes as detectors. The detectors used were thick-film Pt-electrodes in a 3-electrode configuration constructed as sandwich flow-through cells with a volume of about 36 μl polarized at - 900 mV. The measuring principle was the determination of oxygen consumption due to the microbial metabolism. Fructose was used as model analyte. The microorganisms were immobilized on cellulose-acetate membranes and integrated into a newly created reaction chamber (membrane reactor). The microbial cells used were Rhodococcus erythropolis and Issatchenkia orientalis known to be suitable for the determination of biological oxygen demand.
