Die Forschenden der Gruppe Biotechnology & Sustainable Chemistry verfügen über umfangreiches Expertenwissen in den Bereichen Biotechnologie (Pharma, Industrie, Umwelt) und der zugehörigen Analytik. Die Gruppe befasst sich daher mit der gesamten Wertschöpfungskette, die von der Mikro- und Zellbiologie, der Stammverbesserung, der Bioprozessentwicklung, der Produktisolierung und der komplexen analytischen Charakterisierung bis hin zur Qualitätskontrolle mit Hilfe hochmoderner Methoden und Geräte reicht. Die Teammitglieder haben eine ausgewiesene Erfahrung in der Leitung zahlreicher Projekte (europäische Projekte, Mandate, kofinanzierte öffentlich-private- Projekte) in Zusammenarbeit mit Industrie- und Hochschulpartnern.

The BIOTECHNOLOGY & SUSTAINABLE CHEMISTRY group has a strong background in biotechnology (pharma, industrial and environmental) and associated analytics. Consequently, the group covers the complete value chain from microbiology, strain engineering, bioprocess development, product isolation & complex analytical characterization to quality control using state of the art methods and equipment. Its members are experienced in conducting complex various projects (corporate & public co-sponsored, European projects, mandates) with industrial as well as academic partners.
