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.
