Abstract
The present invention relates to a large-scale photosynthetic bioreactor in which transparent photobioreactors including a baffle are connected in parallel or in series by an adhesive element so that the reactor volume can be easily scaled up for scale-up culture of photosynthetic organisms, and to a fabrication method thereof. The large-scale photosynthetic bioreactor according to the present invention makes it possible to culture a larger amount of microalgae than a conventional photobioreactor in the same area. In addition, it has high light transmittance, produces a large amount of biomass per unit area due to smooth mixing, and has a significant effect of reducing carbon dioxide. Furthermore, the present invention has an advantage in that the number of photosynthetic bioreactors required to culture the same scale of photosynthetic organisms is significantly smaller than that in a conventional process for culture of photosynthetic organisms, and thus the operating costs can be reduced.
