Industrial Fermentation

Data

Topic

During the course we employ a set of environmental bacterial strains and use them for various fermentation processes. These bacterial strains include residents of skin and mouth flora, aquatic residents (freshwater and marine), sewage pipeline and agricultural soil residents. We evaluate the ability of such bacterial residents to produce industrially valuable chemicals (on small production scale). We also perform (small scale production) food biotechnology fermentation processes inlcuding the production of cider and yoghurt. General concepts of upscaling and purification, expression systems and bioreactors are also discussed.
