Abstract
The present invention relates to a photobioreactor for the cultivation of photosynthetic micoorganisms having at least one light bank substantially totally immersible in the liquid microbial culture contained in the photobioreactor so that substantially all of the emitted light is absorbed in the culture. The light bank comprises a plurality of light tubes in substantially close proximity to each other, electrical leads extending from the light tubes to a source of electric power and an enclosure means enclosing at least the portions of the electrical leads into the lead tubes to render such points impervious to the liquid microbial culture. The light bank serves as a light source as well as may be arranged to form channels for the circulation of the liquid culture within the photobioreactor.
