Abstract

The apparatus herein relates to the large-scale production of photosynthetic microorganisms, especially algae. More particularly it relates to control of large size aqueous photosynthetic bioreactor systems to obtain such products from many microbial strains, which have heretofore only been cultured in laboratory environments in small containers.

Claims
