Photo bioreactor with light distributor and method for the production of a photosynthetic culture

摘要

The invention provides a photo bioreactor (1) comprising a vessel (10) containing an aqueous liquid comprising a photosynthetic culture and a light distributor (30). The light distributor has a surface (31) arranged to receive light (40) and a tapered surface (32) arranged to emit at least part of the received light. At least part of the tapered surface. (32) is submerged in the aqueous liquid comprising the photosynthetic culture. Light may be distributed efficiently in the aqueous liquid comprising the photosynthetic culture by relatively simple and cheap means. The reactor allows a high illuminated volume fraction.
