ABSTRACT:
An apparatus is disclosed for the controlled production of microorganisms by photosynthesis in a closed photobioreactor. The closed photobioreactor contain a photosynthetic culture in a substantially sealed environment and provides a system for recirculating the reactant gas through the culture. This closed loop system can be operated with expensive carbon isotopes (i.e., .sup.13 CO.sub.2 or .sup.14 CO.sub.2). Also, a system is provided for removing the molecular oxygen produced in the photosynthesis reaction from the closed photobioreactor. Furthermore, a pH-regulated control valve is utilized for controlling the addition of reactant gas to the culture in response to the alkalization of the culture.
