Abstract Photosynthetic microorganisms hold an enormous potential for the production of value-added compounds and fuels either directly from CO2 or via fermentative pathways. A major bottleneck to lift this technology off the ground is the lack of suitable cultivation systems, as the established technologies do not allow cell densities above 3 gCDW / L on an industrial scale. In this chapter, we will introduce cyanobacterial biofilms as an alternative growth format to suspended cell cultures grown in capillary microreactors. Furthermore, biofilms are living systems attached to a surface and thereby exhibit a naturally immobilized microbial community within principle infinite turnover numbers, as the individual cells are constantly regenerating themselves. Therefore, cell densities of up to 50 gCDW/L and long-term stabilities can be achieved.
