Steady-state stability of the DDAP-H fermentations. Time profiles of the succinic acid productivity and yield at steady state for: a the first DDAP-H fermentation at D = 0.04 h‐1 for almost five volume turnovers (120 h), where the slight decrease in yield and productivity towards the end of the time frame are due to biofilm shedding caused by minor pH control issues, and b the second DDAP-H fermentation at D = 0.05 h−1 for just over four volume turnovers (81 h). The points of each graph correspond to the consecutive steady-state points in Fig. 6
