Microalgae have a large biotechnological potential for producing valuable substances for the feed, food, cosmetics and pharmacy industries as well as for biotechnological processes. The design of the technical and technological basis for photobioreactors is the most important issue for economic success in the field of phototrophic biotechnology. For future applications, open pond systems for large-scale production seem to have a lower innovative potential than closed systems. For high-value products in particular, closed systems of photobioreactors seem to be the more promising field for technical developments despite very different approaches in design.
