Research of the "Lehrstuhl für Bioprozesstechnik" established in summer 1999 focuses on the analysis, development, optimization, mathematical modeling and control of bioprocesses at the interface between life sciences and engineering sciences. At present, research focuses on mammalian cell culture for vaccine production, downstream processing for purification of inactivated antigens, dynamics of microbial communities, molecular biology of Rhodospirillum rubrum as well as the use of on-line sensors for bioreactors or waste water treatment plants. Several topics are investigated in close collaboration with the "Max-Planck-Institute for Dynamics of Complex Technical Systems" . These include, characterization of growth and metabolism of mammalian cells, virus dynamics or analysis of virus replication in animal cells by laser scanning microscopy. Furthermore, there is a close cooperation with various partners from academia and industry (see individual projects).
