PCC 6803 biofilm prevented excessive biomass formation and clogging by fundamentally changing the structure of the microbial community. It was possible to continuously operate a capillary microreactor for 5weeks, before the experiment was actively terminated. The biofilm developed up to a thickness of 70-120µm. Surprisingly, the biofilm stopped growing at this thickness and stayed constant without any detachment events occurring afterwards. The substrates CO2 and light were supplied in a counter-current fashion. Confocal microscopy revealed a throughout photosynthetically active biofilm, indicated by the red fluorescence of photo pigments. This control concept and biofilm reaction setup may enable continuous light driven synthesis of value added compounds in future.
