Prof. Manfred Zinn heads the research group Biotechnology and Sustainable Chemistry at the Institute of Life Sciences at HES-SO Valais-Wallis (Sion, Switzerland). Dr. Zinn is specialized in designing bioprocesses for prokaryotes and microbial eukaryotes under heterotrophic and autotrophic conditions and implementing diverse cultivation techniques (batch, fed-batch, multi-stage chemostat, and auxostats). In his lab he is up-scaling bioprocesses from parallel microbioreactor to pilot scale (300 L) using state-of-the-art in process controlling (PAT analytics) has been developed in his group to assess the performance of cells and bioprocesses. A key activity is the tailor-made biosynthesis of PHA in bacteria for sustainable industrial and medical applications. Prof. Zinn has published more than 105 publications in peer reviewed journals and proceedings. Since January 2018 he is chief field editor of the Frontiers Journal Bioprocess and Industrial Biotechnology and since January 2025 he is chairing the EFB Division Biobased Materials.
