The IMMB has a long tradition of research in applied microbiology and biotechnology, and currently harbours 4 groups (Prof. Berg, Prof. Philipp, Prof. Schmid, N.N.). All of them investigate basic and applied aspects of microbiology and enzymology. Many projects are related to biotechnological processes. Targeted molecules are biopolymers such as polysaccharides, polyesters and lipids. Other compounds, such as steroids, heteroaromatic molecules and aromatic flavors are produced by fermentation, enzymatic reaction cascades or biotransformation. New pathways e.g., for CO2-fixation are analysed in the context of bioeconomy research. Metabolic and enzyme as well as strain engineering are the main strengths of the institute. The bioreactor laboratory allows process optimization (parallel fermentations) and scale-up (500-L), so that novel compounds can be produced at the kilogram scale.
