Abstract: Microalgae, with ability to fix CO2 and purify organic wastewater, has attracted much attention in the fields of environmental protection, food and feed (bait), medicine and bio-energy development, etc. However, large-scale cultivation and its industrialization are still the difficulties to be solved urgently. In this paper, the characteristics and structures of photobioreactors, which are often used for large-scale cultivation of microalgae, were reviewed. The closed microalgae photobioreactor can preferably regulate the cultivation conditions of algae species, and is not easy to be polluted. The purity of algae species is easy to be controlled, but the cultivation scale is small and the production cost is high. However, open-type microalgae photobioreactor cannot control the growth environment of algae species accurately, but it is widely used because of its large production scale, high yield and low production cost. The best method is to integrated the two advantages, first, use the closed decay algae bioreactors for pilot light amplifier, a large number of reproductive effects, and then put into open decay algal light bioreactors for large-scale commercial production. The method is hopeful to be micro algae light bioreactors development direction. This paper was expected to provide reference for micro algae large-scale cultivation.
