Efficient Use of Photons in a Photobioreactor
… for this photosynthetic process is known as a photobioreactor. Up until now most of the production is restricted to large open pond or raceway systems with a limited number of closed systems. Open systems which include open ponds and race ways require large land areas and tend to grow low …
