The students will widen further their knowledge of Biotechnology, in particular the role of microorganisms, genetic engineering, enzymes and bioseparations. This knowledge is considered necessary for a Chemical Engineer, since the application of biotechnology is often required both in traditional chemical engineering and in modern biochemical engineering and biomedical applications.
