Abstract
A photobioreactor for the cultivation of photosynthetic microorganisms comprises a tank, one or more light compartments extending into the tank and one or more high intensity lamps whose light is directed into the light compartments. Each light compartment has at least one transparent wall and a means for distributing light from the lamp substantially uniformly across the transparent wall.

A photobioreactor which comprises:
- (a) a tank for containing a liquid microbial culture;
- (b) a high-intensity light source whose light is substantially entirely directed into a light compartment;
- (c) said light compartment having at least one transparent wall extending into said tank;
- and
- (d) said light compartment containing a tube of internally reflective prismatic sheet, said tube extending substantially from said light source to an end wall of said light compartment opposite said light source and said tube having transverse dimensions sufficient to substantially surround said light source, said tube further including a mirror at the end thereof opposite said light source oriented to reflect light back into said tube, wherein the light source, the tube and the mirror are arranged, so as to distribute light from said high-intensity light source substantially uniformly across the interior surface of the transparent wall of said light compartment.
