Microscope images and biofilm from the DDAP-H fermentations. Microscope images from the first DDAP-H fermentation: a during the batch start-up phase, and b after continuous operation at D = 0.02 h−1 for 64 h (approx. 167 h fermentation time); c biofilm attached to the agitator fitting and reactor internals as seen at the termination of the first DDAP-H fermentation
