Figure 2From: High cell density media for Escherichia coli are generally designed for aerobic cultivations – consequences for large-scale bioprocesses and shake flask culturesFormate accumulation profiles in the different types of glucose limited fed-batch cultivations of E. coli W3110 without supplementation of the trace elements selenium, nickel and molybdenum. The data are from the standard glucose-limited fed-batch reference cultivation (○), from the cultivation with the STR-PFR (△), and from the cultivation with a permanent oxygen down-shift (□). Zero hours indicates the time of the feed start.Back to article page
