Dr. Jan Heyland
Jan Heyland was PhD student at the Laboratory of Chemical Biotechnology - Department of Biochemical and Chemical Engineering - at the Dortmund University of Technology (Dortmund, Germany). He studied Biotechnology in the Faculty of Life Sciences at the Hamburg University of Applied Sciences (Hamburg, Germany). For an external traineeship during his studies, he worked in the Department of Chemical Engineering at the University of Queensland (Brisbane, Australia) on hyaluronic acid production in bacteria. The work for his diploma degree (2004) in the field of S. cerevisiae physiology was performed at the Swiss Federal Institute of Technology Zürich in the Department of Biotechnology. Afterwards he worked as a project engineer in the Department of Process Engineering at the Nordmark GmbH & Co. KG (Uetersen, Germany). In 2006 he received his M.Sc. degree in Bioprocess Engineering at the Hamburg University of Applied Sciences. His master thesis was performed at the Hamburg University of Technology (Hamburg, Germany), where he worked on in vitro engineering of articular cartilage.
Quantification of metabolic fluxes is an important analysis technique of metabolic engineering. Metabolic flux analysis provides insights into cellular physiology and thus, knowledge about the response of the intracellular carbon flux distribution in response to genetic modifications or environmental stress. Our focus is on the metabolic response of recombinant yeasts to foreign protein production in industrial relevant processes.
