Oxygen and/or glucose limitation in a chemostat culture of Candida utilis mathematical model identification

The glucose and/or dissolved oxygen limited continuous culture of yeast Candida utilis was studied. Six different mathematical models were designed to describe and analyze the experiments. The model considering the production of surface active compounds at autoanaerobic conditions and dissolved oxygen consumption for nongrowth associated exogeneous respiration yields the best fit. The results may be applied for aerobic waste water treatment plants, process analysis and simulation.
