Photo bioreactor with light distributor and method for the production of a photosynthetic culture
First Claim
1. A photo bioreactor (1) configured to comprise an aqueous liquid (20) comprising a photosynthetic culture (21), said photo bioreactor comprising(a) a plurality of light distributors (30), which light distributors (30) have(i) surfaces (31) configured to receive light (40), and(ii) tapered surfaces (32) configured to emit at least part of the received light (40), wherein at least part of the tapered surfaces (32) are submersible in the aqueous liquid (20), and(b) a construction (300) comprising the plurality of the light distributors (30), which construction is corrugated, and the light distributors (30) are corrugations (308), and(c) a body (60) comprising a plurality of cavities (61) having tapered surfaces (62), with the light distributors (30) and the body (60) configured so that:
- (i) the light distributors (30) are at least partly configured in the cavities (61),(ii) the plurality of cavities (61) form a corrugated counter construction (600),(iii) the tapered surfaces (62) of the cavities (61) are at a distance (d2) from the tapered surfaces (32) of the light distributors (30), creating a channels (64) between the light distributors and the counter construction (600) enabling a uniform flow of liquid (20) between the fluidically connected cavities (61); and
(iv) the construction (300) and the body (60) are a single reactor body (360).

Abstract
The invention provides a photo bioreactor comprising an aqueous liquid comprising a photosynthetic culture and light distributors (30). Each light distributor has a surface arranged to receive light and a tapered surface arranged to emit at least part of the received light. At least part of the tapered surface 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.
