Spirulina is a cyanobacterium which is 55 to 65 % protein by dry weight and contains all essential amino acids. It is also rich in vitamins and chelates toxic metals (removes them from the body).

In economic conditions in which it becomes too expensive to ship fruit and vegetables around the world, food must be grown locally. In cold climates like Germany's, it is very difficult to maintain a balanced diet all year round with locally grown food. As a dietary supplement, spirulina makes it possible to eat locally and eat healthfully.

Spirulina can be grown in ordinary aquariums or bioreactors like the one on display in this room. Under the right conditions, spirulina grows very quickly and a partial harvest can be carried out every day. Consumed fresh it doesn't have the typical algae-taste that many dislike.
