Abstract

This paper describes the design, modelling and experimental characterization of an electrochemical sensor array for on-line monitoring of fermentor conditions in a miniaturized cell assay. The sensor array is capable of monitoring viable yeast concentration, dissolved oxygen concentration, pH and temperature.
