Cover Picture: Biotechnology Journal 9/2016

This regular issue of BTJ includes articles on bioprocess engineering and biochemical engineering. Also it contains two special articles to the topic ‘Eukaryotic Synthetic Biology’. The cover shows mouse embryonic stem cells proliferating in a microfluidic culture device capable of monitoring specific oxygen uptake rates in real time. Monitoring occurs without disruption of the cell culture and label‐free. Image is provided by Alexandre Super, Nicolas Jaccard, Marco Paulo Cardoso Marques, Rhys Jarred Macown, Lewis D. Griffin, Farlan Singh Veraitch and Nicolas Szita authors of ‘Real‐time monitoring of specific oxygen uptake rates of embryonic stem cells in a microfluidic cell culture device’ ( http://dx.doi.org/10.1002/biot.201500479 ).
