The basic concepts of the biorefineries and the contribution of photosynthetic organisms to blue and green biorefineries will be discussed. 

Content: Photosynthesis as a starting point for biorefineriesphotosynthetic organisms as a source of food, feed, and fuel; bottle-necks and strategies to improve cost-effectiveness of bio-based production systems; detection methods for assessing the value of different end-products (lipids, carotenoids, H2gas etc).
