The Joint Conference of the DFG Priority Programs SPP 2240 eBiotech and SPP 2170 "InterZell" took place in Jena. The meeting was hosted at the Leibniz-HKI in Jena on November 6-7, 2023, followed by an autumn school for doctoral researchers from both programs on November 8, 2023. We were happy to bring scientists from SPP 2170 InterZell and SPP 2240 eBiotech together at this occasion for stimulating discussions and fruitful exchange about our common research themes of biochemical engineering and process development. We were joined by international keynote speakers (Amelia Rotaru, Bas Teusink, Kylie Vincent, Volker Wendisch). We thank all the organizers and specially Miriam A. Rosenbaum and Ralf Takors!
