Abstract

For state estimation of yeast growth and alcohol production in batch stirred-tank reactors the following process variables were measured on line: glucose (with a polarimeter or chemical reaction), orthophosphates (photometer), ammonium (ion selective electrode and NaOH/EDTA reagent), dissolved ethanol and CO2 (mass spectrometer), pO2 (Clark electrode) in medium as well as CO2 (IR) and O2 (paramagnetic effect) in exhaust gas. The sterile sampling procedures and transient functions of the analyzer systems are explored. The on-line evaluated data and a mathematical model were used to develop a state estimator and adaptive control, which are discussed in a separate paper.
